格式和修改命名区域

格式化区域

将背景颜色和字体属性设置为已命名范围

要应用格式设置,定义一个Style对象以指定样式设置,并将其应用于Range对象。

以下示例显示如何为范围设置实填充颜色(着色颜色)并带有字体设置。

// 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");

为已命名范围添加边框

可以为一系列的单元格添加边框,而不仅仅是单个单元格。Range对象提供了一个SetOutlineBorder方法,以及以下参数来向单元格范围添加边框:

  • 边框类型,边框的类型,从BorderType枚举中选择。
  • 线条样式,线条的样式,从CellBorderType枚举中选择。
  • 颜色,线条颜色,从Color枚举中选择。

以下示例显示如何将范围设置为轮廓边框。

// 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");

以下示例显示了如何在范围中的每个单元格周围设置边框。

// 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");

重命名命名范围

Aspose.Cells允许您根据需要重命名已命名范围。您可以通过使用Name.Text属性获取命名范围并将其重命名。以下示例显示如何重命名已命名范围。

// 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");

范围的并集

Aspose.Cells提供了Range.Union方法来获取范围的并集,该方法返回一个ArrayList对象。以下示例显示了如何获取范围的并集。

// 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();
// 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");

范围的交集

Aspose.Cells提供Range.Intersect方法以求两个范围的交集。该方法返回Range对象。要检查一个范围是否与另一个范围相交,请使用返回布尔值的Range.Intersect方法。以下示例显示如何求范围的交集。

// 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");

合并命名范围中的单元格

Aspose.Cells提供Range.Merge()方法以合并范围中的单元格。以下示例显示如何合并命名范围的单元格。

// 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 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");

移除命名范围

Aspose.Cells提供了NameCollection.RemoveAt()方法来删除命名范围的名称。要清除范围的内容,使用Cells.ClearRange()方法。以下示例显示了如何删除带有内容的命名范围。

// 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 all the worksheets in the book.
WorksheetCollection worksheets = workbook.Worksheets;
// Get the first worksheet in the worksheets collection.
Worksheet worksheet = workbook.Worksheets[0];
// Create a range of cells.
Range range1 = worksheet.Cells.CreateRange("E12", "I12");
// Name the range.
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);
worksheets.Names.RemoveAt(0);
// Save the excel file.
workbook.Save(dataDir + "copyranges.out.xls");
