名前付き範囲の式の設定

名前付き範囲の式の設定

Aspose.CellsのAPIは、参照先プロパティを使用して、名前付き範囲の式を指定する機能を提供します。この機能には多くの使用シナリオがあり、そのうちのいくつかは以下に詳細に記載されています。

名前付き範囲に簡単な式を設定する

簡単な式は、同じワークシート(または異なるワークシート)内の別のセルへの参照である場合があります。次の例は、新しいスプレッドシートで名前付き範囲を作成し、その参照先を別のセルに設定します。

// 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 an instance of Workbook
Workbook book = new Workbook();
// Get the WorksheetCollection
WorksheetCollection worksheets = book.Worksheets;
// Add a new Named Range with name "NewNamedRange"
int index = worksheets.Names.Add("NewNamedRange");
// Access the newly created Named Range
Name name = worksheets.Names[index];
// Set RefersTo property of the Named Range to a formula. Formula references another cell in the same worksheet
name.RefersTo = "=Sheet1!$A$3";
// Set the formula in the cell A1 to the newly created Named Range
worksheets[0].Cells["A1"].Formula = "NewNamedRange";
// Insert the value in cell A3 which is being referenced in the Named Range
worksheets[0].Cells["A3"].PutValue("This is the value of A3");
// Calculate formulas
book.CalculateFormula();
// Save the result in XLSX format
book.Save(dataDir + "output_out.xlsx");

名前付き範囲に複雑な式を設定する

複雑な式は、動的な範囲や異なるワークシートの複数のセルにまたがる式など、さまざまなものになります。次の例は、INDEX 関数を使用して、リスト内の位置に基づいて値を取得する動的な範囲を作成します。

// 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 an instance of Workbook
Workbook book = new Workbook();
// Get the WorksheetCollection
WorksheetCollection worksheets = book.Worksheets;
// Add a new Named Range with name "data"
int index = worksheets.Names.Add("data");
// Access the newly created Named Range from the collection
Name data = worksheets.Names[index];
// Set RefersTo property of the Named Range to a cell range in same worksheet
data.RefersTo = "=Sheet1!$A$1:$A$10";
// Add another Named Range with name "range"
index = worksheets.Names.Add("range");
// Access the newly created Named Range from the collection
Name range = worksheets.Names[index];
// Set RefersTo property to a formula using the Named Range data
range.RefersTo = "=INDEX(data,Sheet1!$A$1,1):INDEX(data,Sheet1!$A$1,9)";
// Save the workbook
book.Save(dataDir + "output_out.xlsx");

異なるワークシートの2つのセルから値を合計する名前付き範囲を使用するもう1つの例がこちら

// 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 an instance of Workbook
Workbook book = new Workbook();
// Get the WorksheetCollection
WorksheetCollection worksheets = book.Worksheets;
// Insert some data in cell A1 of Sheet1
worksheets["Sheet1"].Cells["A1"].PutValue(10);
// Add a new Worksheet and insert a value to cell A1
worksheets[worksheets.Add()].Cells["A1"].PutValue(10);
// Add a new Named Range with name "range"
int index = worksheets.Names.Add("range");
// Access the newly created Named Range from the collection
Name range = worksheets.Names[index];
// Set RefersTo property of the Named Range to a SUM function
range.RefersTo = "=SUM(Sheet1!$A$1,Sheet2!$A$1)";
// Insert the Named Range as formula to 3rd worksheet
worksheets[worksheets.Add()].Cells["A1"].Formula = "range";
// Calculate formulas
book.CalculateFormula();
// Save the result in XLSX format
book.Save(dataDir + "output_out.xlsx");
