命名范围的设置公式

命名范围的设置公式

与 Excel 应用程序一样，Aspose.Cells API 提供了在使用其命名范围时指定公式的能力指的是财产。此功能可能有许多可用性场景，其中一些场景详述如下。

为命名范围设置一个简单的公式

一个简单的公式可以是对相同（或不同）工作表中另一个单元格的引用。以下示例在新电子表格中创建一个命名范围并将其引用设置为另一个单元格。

// 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 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");

为命名范围设置复杂公式

复杂的公式可以是任何东西，例如动态范围或跨越不同工作表中多个单元格的公式。以下示例使用 INDEX 函数创建一个动态范围，以根据其位置从列表中获取值。

// 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");

下面是另一个示例，它使用命名范围对不同工作表中 2 个单元格的值求和。

// 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");
