Formattare e modificare intervalli con nome

Formattare intervalli

Impostazione del colore di sfondo e degli attributi del carattere su un intervallo nominato

Per applicare la formattazione, definire un oggetto Style per specificare le impostazioni dello stile e applicarlo all’oggetto Range.

Nell’esempio seguente viene mostrato come impostare il colore di riempimento solido (colore ombreggiatura) con impostazioni del carattere a un intervallo.

// For complete examples and data files, please go to https://github.com/aspose-cells/Aspose.Cells-for-.NET
// The path to the documents directory.
string dataDir = RunExamples.GetDataDir(System.Reflection.MethodBase.GetCurrentMethod().DeclaringType);
// Create directory if it is not already present.
bool IsExists = System.IO.Directory.Exists(dataDir);
if (!IsExists)
System.IO.Directory.CreateDirectory(dataDir);
// Instantiate a new Workbook.
Workbook workbook = new Workbook();
// Get the first worksheet in the book.
Worksheet WS = workbook.Worksheets[0];
// Create a range of cells.
Aspose.Cells.Range range = WS.Cells.CreateRange(1, 1, 1, 18);
// Name the range.
range.Name = "MyRange";
// Declare a style object.
Style stl;
// Create/add the style object.
stl = workbook.CreateStyle();
// Specify some Font settings.
stl.Font.Name = "Arial";
stl.Font.IsBold = true;
// Set the font text color
stl.Font.Color = Color.Red;
// To Set the fill color of the range, you may use ForegroundColor with
// Solid Pattern setting.
stl.ForegroundColor = Color.Yellow;
stl.Pattern = BackgroundType.Solid;
// Create a StyleFlag object.
StyleFlag flg = new StyleFlag();
// Make the corresponding attributes ON.
flg.Font = true;
flg.CellShading = true;
// Apply the style to the range.
range.ApplyStyle(stl, flg);
// Save the excel file.
workbook.Save(dataDir + "rangestyles.out.xls");

Aggiunta di bordi a un intervallo nominato

È possibile aggiungere i bordi a un intervallo di celle invece che a una singola cella. L’oggetto Range fornisce un metodo SetOutlineBorder che accetta i seguenti parametri per aggiungere un bordo all’intervallo di celle:

  • Tipo di bordo, il tipo di bordo, selezionato dall’enumerazione BorderType.
  • Stile della linea, lo stile della linea, selezionato dall’enumerazione CellBorderType.
  • Colore, il colore della linea, selezionato dall’enumerazione Colore.

L’esempio seguente mostra come impostare un bordo di contorno a un intervallo.

// For complete examples and data files, please go to https://github.com/aspose-cells/Aspose.Cells-for-.NET
// The path to the documents directory.
string dataDir = RunExamples.GetDataDir(System.Reflection.MethodBase.GetCurrentMethod().DeclaringType);
// Create directory if it is not already present.
bool IsExists = System.IO.Directory.Exists(dataDir);
if (!IsExists)
System.IO.Directory.CreateDirectory(dataDir);
// Instantiating a Workbook object
Workbook workbook = new Workbook();
// Clears the worksheets
workbook.Worksheets.Clear();
// Adding a new worksheet to the Workbook object
workbook.Worksheets.Add();
// Obtaining the reference of the newly added worksheet by passing its sheet index
Worksheet worksheet = workbook.Worksheets[0];
// Accessing the "A1" cell from the worksheet
Cell cell = worksheet.Cells["A1"];
// Adding some value to the "A1" cell
cell.PutValue("Hello World From Aspose");
// Creating a range of cells starting from "A1" cell to 3rd column in a row
Range range = worksheet.Cells.CreateRange(0, 0, 1, 3);
// Adding a thick top border with blue line
range.SetOutlineBorder(BorderType.TopBorder, CellBorderType.Thick, Color.Blue);
// Adding a thick bottom border with blue line
range.SetOutlineBorder(BorderType.BottomBorder, CellBorderType.Thick, Color.Blue);
// Adding a thick left border with blue line
range.SetOutlineBorder(BorderType.LeftBorder, CellBorderType.Thick, Color.Blue);
// Adding a thick right border with blue line
range.SetOutlineBorder(BorderType.RightBorder, CellBorderType.Thick, Color.Blue);
// Saving the Excel file
workbook.Save(dataDir + "book1.out.xls");

Il seguente esempio mostra come impostare i bordi intorno ad ogni cella nell’intervallo.

// For complete examples and data files, please go to https://github.com/aspose-cells/Aspose.Cells-for-.NET
// The path to the documents directory.
string dataDir = RunExamples.GetDataDir(System.Reflection.MethodBase.GetCurrentMethod().DeclaringType);
// Instantiate a new Workbook.
Workbook workbook = new Workbook();
// Access the cells in the first worksheet.
Cells cells = workbook.Worksheets[0].Cells;
// Create a range of cells.
Range range = cells.CreateRange("A6", "P216");
// Declare style.
Style stl;
// Create the style adding to the style collection.
stl = workbook.CreateStyle();
// Specify the font settings.
stl.Font.Name = "Arial";
stl.Font.IsBold = true;
stl.Font.Color = Color.Blue;
// Set the borders
stl.Borders[BorderType.TopBorder].LineStyle = CellBorderType.Thin;
stl.Borders[BorderType.TopBorder].Color = Color.Blue;
stl.Borders[BorderType.LeftBorder].LineStyle = CellBorderType.Thin;
stl.Borders[BorderType.LeftBorder].Color = Color.Blue;
stl.Borders[BorderType.BottomBorder].LineStyle = CellBorderType.Thin;
stl.Borders[BorderType.BottomBorder].Color = Color.Blue;
stl.Borders[BorderType.RightBorder].LineStyle = CellBorderType.Thin;
stl.Borders[BorderType.RightBorder].Color = Color.Blue;
// Create StyleFlag object.
StyleFlag flg = new StyleFlag();
// Make the corresponding formatting attributes ON.
flg.Font = true;
flg.Borders = true;
// Apply the style with format settings to the range.
range.ApplyStyle(stl, flg);
// Save the excel file.
workbook.Save( dataDir + "output.xls");

Rinomina un intervallo nominato

Aspose.Cells ti consente di rinominare un intervallo con nome secondo le tue esigenze. Puoi ottenere l’intervallo con nome e rinominarlo usando l’attributo Name.Text. Nell’esempio seguente viene mostrato come rinominare un intervallo con nome.

// For complete examples and data files, please go to https://github.com/aspose-cells/Aspose.Cells-for-.NET
// The path to the documents directory.
string dataDir = RunExamples.GetDataDir(System.Reflection.MethodBase.GetCurrentMethod().DeclaringType);
// Open an existing Excel file that has a (global) named range "TestRange" in it
Workbook workbook = new Workbook(dataDir + "book1.xls");
// Get the first worksheet
Worksheet sheet = workbook.Worksheets[0];
// Get the Cells of the sheet
Cells cells = sheet.Cells;
// Get the named range "MyRange"
Name name = workbook.Worksheets.Names["TestRange"];
// Rename it
name.Text = "NewRange";
// Save the Excel file
workbook.Save(dataDir + "RenamingRange.out.xlsx");

Unione di intervalli

Aspose.Cells fornisce il metodo Range.Union per unire gli intervalli, il metodo restituisce un oggetto ArrayList. Nell’esempio seguente viene mostrato come unire gli intervalli.

// The path to the documents directory.
string dataDir = RunExamples.GetDataDir(System.Reflection.MethodBase.GetCurrentMethod().DeclaringType);
// Instantiate a workbook object.
// Open an existing excel file.
Workbook workbook = new Workbook(dataDir + "book1.xls");
// Get the named ranges.
Range[] ranges = workbook.Worksheets.GetNamedRanges();
// Create a style object.
Style style = workbook.CreateStyle();
// Set the shading color with solid pattern type.
style.ForegroundColor = Color.Yellow;
style.Pattern = BackgroundType.Solid;
// Create a styleflag object.
StyleFlag flag = new StyleFlag();
// Apply the cellshading.
flag.CellShading = true;
// Creates an arraylist.
ArrayList al = new ArrayList();
// Get the arraylist collection apply the union operation.
al = ranges[0].UnionRanges(ranges[1]);
// Define a range object.
Range rng;
int frow, fcol, erow, ecol;
for (int i = 0; i < al.Count; i++)
{
// Get a range.
rng = (Range)al[i];
frow = rng.FirstRow;
fcol = rng.FirstColumn;
erow = rng.RowCount;
ecol = rng.ColumnCount;
// Apply the style to the range.
rng.ApplyStyle(style, flag);
}
// Save the excel file.
workbook.Save(dataDir + "rngUnion.out.xls");

Intersezione di intervalli

Aspose.Cells fornisce il metodo Range.Intersect per intersecare due intervalli. Il metodo restituisce un oggetto Range. Per verificare se un intervallo interseca un altro intervallo, utilizzare il metodo Range.Intersect che restituisce un valore booleano. L’esempio seguente mostra come intersecare gli intervalli.

// For complete examples and data files, please go to https://github.com/aspose-cells/Aspose.Cells-for-.NET
// The path to the documents directory.
string dataDir = RunExamples.GetDataDir(System.Reflection.MethodBase.GetCurrentMethod().DeclaringType);
// Instantiate a workbook object.
// Open an existing excel file.
Workbook workbook = new Workbook(dataDir + "book1.xls");
// Get the named ranges.
Range[] ranges = workbook.Worksheets.GetNamedRanges();
// Check whether the first range intersect the second range.
bool isintersect = ranges[0].IsIntersect(ranges[1]);
// Create a style object.
Style style = workbook.CreateStyle();
// Set the shading color with solid pattern type.
style.ForegroundColor = Color.Yellow;
style.Pattern = BackgroundType.Solid;
// Create a styleflag object.
StyleFlag flag = new StyleFlag();
// Apply the cellshading.
flag.CellShading = true;
// If first range intersects second range.
if (isintersect)
{
// Create a range by getting the intersection.
Range intersection = ranges[0].Intersect(ranges[1]);
// Name the range.
intersection.Name = "Intersection";
// Apply the style to the range.
intersection.ApplyStyle(style, flag);
}
// Save the excel file.
workbook.Save(dataDir + "rngIntersection.out.xls");

Unisci celle nell’intervallo nominato

Aspose.Cells fornisce il metodo Range.Merge() per unergere le celle nell’intervallo. Nell’esempio seguente viene mostrato come unire le celle individuali di un intervallo nominato.

// For complete examples and data files, please go to https://github.com/aspose-cells/Aspose.Cells-for-.NET
// The path to the documents directory.
string dataDir = RunExamples.GetDataDir(System.Reflection.MethodBase.GetCurrentMethod().DeclaringType);

bool IsExists = System.IO.Directory.Exists(dataDir);
if (!IsExists)
System.IO.Directory.CreateDirectory(dataDir);
// Instantiate a new Workbook.
Workbook wb1 = new Workbook();
// Get the first worksheet in the workbook.
Worksheet worksheet1 = wb1.Worksheets[0];
// Create a range.
Range mrange = worksheet1.Cells.CreateRange("A18", "J18");
// Name the range.
mrange.Name = "Details";
// Merge the cells of the range.
mrange.Merge();
// Get the range.
Range range1 = wb1.Worksheets.GetRangeByName("Details");
// Define a style object.
Style style = wb1.CreateStyle();
// Set the alignment.
style.HorizontalAlignment = TextAlignmentType.Center;
// Create a StyleFlag object.
StyleFlag flag = new StyleFlag();
// Make the relative style attribute ON.
flag.HorizontalAlignment = true;
// Apply the style to the range.
range1.ApplyStyle(style, flag);
// Input data into range.
range1[0, 0].PutValue("Aspose");
// Save the excel file.
wb1.Save(dataDir + "mergingrange.out.xls");

Rimuovere un intervallo nominato

Aspose.Cells fornisce il metodo NameCollection.RemoveAt() per cancellare il nome dell’intervallo. Per cancellare il contenuto dell’intervallo, utilizzare il metodo Cells.ClearRange(). Nell’esempio seguente viene mostrato come rimuovere un intervallo nominato con il suo contenuto.

// For complete examples and data files, please go to https://github.com/aspose-cells/Aspose.Cells-for-.NET

range1.Name = "MyRange";
// Set the outline border to the range.
range1.SetOutlineBorder(BorderType.TopBorder, CellBorderType.Medium, Color.FromArgb(0, 0, 128));
range1.SetOutlineBorder(BorderType.BottomBorder, CellBorderType.Medium, Color.FromArgb(0, 0, 128));
range1.SetOutlineBorder(BorderType.LeftBorder, CellBorderType.Medium, Color.FromArgb(0, 0, 128));
range1.SetOutlineBorder(BorderType.RightBorder, CellBorderType.Medium, Color.FromArgb(0, 0, 128));
// Input some data with some formattings into
// A few cells in the range.
range1[0, 0].PutValue("Test");
range1[0, 4].PutValue("123");
// Create another range of cells.
Range range2 = worksheet.Cells.CreateRange("B3", "F3");
// Name the range.
range2.Name = "testrange";
// Copy the first range into second range.
range2.Copy(range1);
// Remove the previous named range (range1) with its contents.
worksheet.Cells.ClearRange(11, 4, 11, 8);
