Answer 1

You can color a cell or a entire column or entire row.

The below code will help you out.

xlWorkSheet.get_Range(xlWorkSheet.Cells[2, 2], xlWorkSheet.Cells[2, 4]).Interior.Color = System.Drawing.ColorTranslator.ToOle(System.Drawing.Color.Green);

else

xlWorkSheet.get_Range(xlWorkSheet.Cells[2, 3], xlWorkSheet.Cells[2, 3]).Interior.Color = Excel.XlRgbColor.rgbRed;

Here xlWorksheet is the object excel Worksheet object.

get_Range takes 2 variable one start cell and other is end cell.

so if you specify both the values same then only one cell is colored.

xlWorkSheet.cells[row, column] is used to specify a cell.

System.Drawing.ColorTranslator.ToOle(SystemDrawing.Color.Green) is used to define the color in OLE format.

Excel.XlRgbColor.rgbRed is a excel way of coloring the cells This method gives access to large number of colors which can be found here list of colors

The below code is the way i defined the excel worksheet.

Excel.Workbook xlWorkBook;
Excel.Worksheet xlWorkSheet;
Excel.Range xlwidthadjust; //used this to adjust width of columns
object misValue = System.Reflection.Missing.Value;

xlWorkBook = xlApp.Workbooks.Add(misValue);
xlWorkSheet = (Excel.Worksheet)xlWorkBook.Worksheets.get_Item(1);

with this code i am sure that you wont get this exception Exception from HRESULT: 0x800A03EC
