Can anyone tell me how to convert excel file into images using C# code and Microsoft.Office.Interop.Excel lib?

C#

Using Microsoft.Office.Interop.Excel;             

string fileNameToProcess = @"C:\Users\infoobjects\Desktop\Test1 Single sheet.xlsx";
            //Start Excel and create a new document.
            xls.Application oExcel = new xls.Application();
            xls.Workbook wb = null;
            try
            {
                wb = oExcel.Workbooks.Open(fileNameToProcess.ToString(), false, false, Type.Missing, "", "", true, xls.XlPlatform.xlWindows, "", false, false, 0, false, true, 0);
                //wb.RefreshAll();
                xls.Sheets sheets = wb.Worksheets as xls.Sheets;
                for (int i = 1; i <= sheets.Count; i++)
                {
                    xls.Worksheet sheet = sheets[i];
                    //Following is used to find range with data
                    string startRange = "A1";
                    Microsoft.Office.Interop.Excel.Range endRange = sheet.Cells.SpecialCells(Microsoft.Office.Interop.Excel.XlCellType.xlCellTypeLastCell, Type.Missing);
                    xls.Range range = sheet.get_Range(startRange, endRange);
                    range.Rows.AutoFit();
                    range.Columns.AutoFit();
                    range.Copy();
                    System.Drawing.Image imgRange1 = Clipboard.GetImage();
                    imgRange1.Save(@"C:\Users\infoobjects\Desktop\" + "Test1" + i + ".Jpeg", System.Drawing.Imaging.ImageFormat.Jpeg);
                    Console.Write("Specified range converted to image successfully. Press Enter to continue.");
                    sheets[i].Delete();
                }

                wb.Save();
            }
            catch (Exception ex)
            {
                Console.WriteLine(ex.Message);
                //throw;
            }
            finally
            {
                wb.Close();
                oExcel.Quit();
                oExcel = null;
            }

            Console.ReadLine();

It will create a single image of the excel sheet based on the cell used in the sheet, but I want to create multiple images(If required) according to the A4 size sheet.

You have a choice of creating it manually by building an image from the actual data content, or by displaying the relevant portion of the worksheet and using screen capture to create the image.
