Adding hyperlinks in Excel[2007] in C# - Within Excel it self

Question

Can anybody tell me how we can add a hyperlink in Excel (2007 or later) from a cell in one sheet to a cell in another sheet using Office Interop in .NET (c#)

For example: A hyperlink from Sheet1 Cell A1 to Sheet2 Cell B10

What you want to use here is the Hyperlinks.Add method.

You can call it with code that looks something like this:

Excel.Worksheet worksheet = (Excel.Worksheet)workbook.Worksheets[1];
Excel.Range rangeToHoldHyperlink = worksheet.get_Range("A1", Type.Missing);
string hyperlinkTargetAddress = "Sheet2!A1";

worksheet.Hyperlinks.Add(
    rangeToHoldHyperlink,
    string.Empty,
    hyperlinkTargetAddress,
    "Screen Tip Text",
    "Hyperlink Title");

Here is a full automation example that you can test:

void AutomateExcel()
{
    Excel.Application excelApp = new Excel.Application();
    excelApp.Visible = true;

    Excel.Workbook workbook = excelApp.Workbooks.Add(Type.Missing);
    workbook.Worksheets.Add(Type.Missing, Type.Missing, Type.Missing, Type.Missing);
    workbook.Worksheets.Add(Type.Missing, Type.Missing, Type.Missing, Type.Missing);

    Excel.Worksheet worksheet = (Excel.Worksheet)workbook.Worksheets[1];
    Excel.Range rangeToHoldHyperlink = worksheet.get_Range("A1", Type.Missing);
    string hyperlinkTargetAddress = "Sheet2!A1";

    worksheet.Hyperlinks.Add(
        rangeToHoldHyperlink,
        string.Empty,
        hyperlinkTargetAddress,
        "Screen Tip Text",
        "Hyperlink Title");

    MessageBox.Show("Ready to clean up?");

   // Cleanup:
    GC.Collect();
    GC.WaitForPendingFinalizers();
    GC.Collect();
    GC.WaitForPendingFinalizers();

    Marshal.FinalReleaseComObject(range);

    Marshal.FinalReleaseComObject(worksheet);

    workbook.Close(false, Type.Missing, Type.Missing);
    Marshal.FinalReleaseComObject(workbook);

    excelApp.Quit();
    Marshal.FinalReleaseComObject(excelApp);
}

Hope this helps!
