Duplicate of: What’s the simplest way to import a System.Data.DataSet into Excel?

Using c# under VS2008, we can create an excel app, workbook, and then worksheet fine by doing this:

        Application excelApp = new Application();
        Workbook excelWb = excelApp.Workbooks.Add(template);
        Worksheet excelWs = (Worksheet)this.Application.ActiveSheet;

Then we can access each cell by "excelWs.Cells[i,j]" and write/save without problems. However with large numbers of rows/columns, we are expecting a loss in efficiency.

Is there a way to "data bind" from a DataSet object into the worksheet without using the cell-by-cell approach? Most of the methods we have seen at some point revert to the cell-by-cell approach. Thanks for any suggestions.
