microsoft.interop.excel Formatting cells

Question

I am building a report using the microsoft.interop.excel library in C#.

I have something like this:

 Range rangeTarget;
 .
 .
 .
 rangeTarget = worksheet.get_Range("C" + row, "N" + row);

I want the range to display its values as whole numbers i.e. with no decimal places. I've tried rangeTarge.AutoFormat, but have no idea how to use it.

Any Ideas ?

Thanks.

Answer 1

see MSDN

Microsoft.Office.Tools.Excel.NamedRange namedRange1 =
this.Controls.AddNamedRange(this.Range["A1", "A5"], "namedRange1");

namedRange1.NoteText("This is a Formatting test", missing, missing);
namedRange1.Value2 = "Martha";
namedRange1.Font.Name = "Verdana";
namedRange1.VerticalAlignment = Excel.XlVAlign.xlVAlignCenter;
namedRange1.HorizontalAlignment = Excel.XlHAlign.xlHAlignCenter;
namedRange1.BorderAround(missing, Excel.XlBorderWeight.xlThick,
    Excel.XlColorIndex.xlColorIndexAutomatic, missing);
namedRange1.AutoFormat(Excel.XlRangeAutoFormat.xlRangeAutoFormat3DEffects1,
    true, false, true, false, true, true);

if (MessageBox.Show("Clear the formatting and notes?", "Test",
    MessageBoxButtons.YesNo) == DialogResult.Yes)
{
    namedRange1.ClearFormats();
    namedRange1.ClearNotes();
}

I don't know what the other formats are but you can look on the MSDN.

Excel.Range ThisRange = ThisSheet.get_Range("A:A",system.type.missing);
ThisRange.NumberFormat = "0.00%";
ThisRange.NumberFormat = "General";    
ThisRange.NumberFormat = "hh:mm:ss";
ThisRange.NumberFormat = "DD/MM/YYYY";

Marshal.FinalReleaseComObject(ThisRange);
