名前付き範囲の数式の設定

名前付き範囲の数式の設定

Excel アプリケーションと同様に、Aspose.Cells API は、名前付き範囲の数式を指定する機能を提供します。参照先財産。この機能には多数のユーザビリティ シナリオが考えられますが、そのうちのいくつかを以下に詳しく説明します。

名前付き範囲の単純な式の設定

単純な数式は、同じ (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可能性があります。次の例では、新しいスプレッドシートに名前付き範囲を作成し、その参照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");

名前付き範囲の複雑な数式の設定

複雑な数式は、ダイナミック レンジや、異なるワークシートの複数のセルにまたがる数式など、あらゆるものである可能性があります。次の例では、INDEX 関数を使用して動的範囲を作成し、その場所に基づいてリストから値を取得します。

// 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");

名前付き範囲を使用して、異なるワークシートの 2 つのセルの値を合計する別の例を次に示します。

// 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;

// 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");
