Creating a Named Range in VSTO and Aspose.Cells

To create a named range:

1. Set up the worksheet:
   1. Instantiate an Application object.(VSTO only.)
   2. Add a Workbook.
   3. Get the first sheet.
2. Create a named range:
   1. Define a range.
   2. Name the range.
   3. Save the file.

The code examples below show how to perform these steps using VSTO with either C#. The code examples that follow show how to do the same thing using Aspose.Cells for .NET, again with either C#.

VSTO

 //Create Excel Object

Excel.Application xl = Application;

//Create a new Workbook

Excel.Workbook wb = xl.Workbooks.Add(Missing.Value);

//Get Worksheets Collection

Excel.Sheets xlsheets = wb.Sheets;

//Select the first sheet

Excel.Worksheet excelWorksheet = (Excel.Worksheet)xlsheets[1];

//Select a range of cells

Excel.Range range = (Excel.Range)excelWorksheet.get_Range("A1:B4", Type.Missing);

//Add Name to Range

range.Name = "Test_Range";

//Put data in range cells

foreach (Excel.Range cell in range.Cells)

{

	cell.set_Value(Missing.Value, "Test");

}

//Save New Workbook

wb.SaveCopyAs("Test_Range.xls");

//Quit Excel Object

xl.Quit();

Aspose.Cells

 //Instantiating a Workbook object

Workbook workbook = new Workbook();

//Accessing the first worksheet in the Excel file

Worksheet worksheet = workbook.Worksheets[0];

//Creating a named range

Range range = worksheet.Cells.CreateRange("A1", "B4");

//Setting the name of the named range

range.Name = "Test_Range";

for (int row = 0; row < range.RowCount; row++)

{

	for (int column = 0; column < range.ColumnCount; column++)

	{

		range[row, column].PutValue("Test");

	}

}

//Saving the modified Excel file in default (that is Excel 2003) format

workbook.Save("Test_Range.xls");
