  • Hi harikiran2010,

    You can use Range.Delete Method to delete rows.

    Like this, I delete the first two lines:

                ApplicationClass excel = new ApplicationClass();
                Workbook workbook = excel.Workbooks.Open(@"D:\test\excel\2.xlsx");
                Worksheet worksheet = (Worksheet)workbook.ActiveSheet;
                int startRow = 1;
                int endRow = 2;
                for (int i = startRow; i < endRow; i++)

    This code needs to install a nuget package first:Microsoft.Office.Interop.Excel

    Best Regards,

  • The question does look like homework or offline interview tasks.

    In this case it's better to ask what the asker have done so far, like what Kareninstructor do here, instead of directly posting answers.

    EDIT: Okay I see you're not posting direct answer either.
