Obtaining Excel worksheet reference by worksheet n

问题:

I'm currently obtaining a handle to a Excel worksheet by using the below C# code:

Excel.Worksheet worksheet = (Excel.Worksheet)sheets.get_Item(15);
//Get the worksheet "SubSignOff" number

Is there any way that I can obtain the same by using the worksheet name "SubSignOff" ?

Instead of the using Excel.Workbook.Sheets collection, it's easier to access the Excel.Workbook.Worksheets collection, that way you can utilize early binding.

In your case, it could look something like the following:

Excel.Application excelApp = new Excel.Application();
excelApp.Visible = true;

Excel.Workbook workbook = excelApp.Workbooks.Open("C:\MyWorkbook.xls",
    Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing, 
    Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing, 
    Type.Missing, Type.Missing, Type.Missing, Type.Missing);

// The key line:
Excel.Worksheet worksheet = (Excel.Worksheet)workbook.Worksheets["SubSignOff"];

Hope this helps...
