Merge or UnMerge Cells in a Worksheet in VSTO and Aspose.Cells

Open an existing excel file, Merge some cells in the first worksheet in the workbook and save the excel file.

Merging Cells

VSTO

Following are the parallel code snippets for VSTO (C#) and Aspose.Cells for .NET (C#).

 //Instantiate the Application object.

 Excel.Application excelApp = Application;

//Specify the template excel file path.

 string myPath = "Book1.xls";

//Open the excel file.

 excelApp.Workbooks.Open(myPath, Missing.Value, Missing.Value,

            Missing.Value, Missing.Value,

            Missing.Value, Missing.Value,

            Missing.Value, Missing.Value,

            Missing.Value, Missing.Value,

            Missing.Value, Missing.Value,

            Missing.Value, Missing.Value);

//Get the range of cells i.e.., A1:C1.

 Excel.Range rng1 = excelApp.get_Range("A1", "C1");

//Merge the cells.

 rng1.Merge(Missing.Value);

 rng1 = excelApp.get_Range("A1", Missing.Value);

//Save the file.

 excelApp.ActiveWorkbook.Save();

//Quit the Application.

 excelApp.Quit();

Aspose.Cells

 //Instantiate a new Workbook.

  Workbook workbook = new Workbook();

//Specify the template excel file path.

 string myPath = "Book1.xls";

//Open the excel file.

 workbook.Open(myPath);

//Get the range of cells i.e.., A1:C1.

 Aspose.Cells.Range rng1 = workbook.Worksheets[0].Cells.CreateRange("A1", "C1");

//Merge the cells.

 rng1.Merge();

//Save the file.

  workbook.Save("Book1.xls");

UnMerging Cells

To unmerge the cell(s), use the following lines of code for VSTO (C#) and Aspose.Cells for .NET (C#).

VSTO

 //UnMerge the cell.

  rng1.UnMerge();

Aspose.Cells

   Cells rng = workbook.Worksheets[0].Cells;

//UnMerge the cell.

  rng.UnMerge(0, 0, 1, 3);
