在用Excel作報表的時候，可能需要操作單元格的邊框和填充顏色和紋理等操作，下面的代碼說明如何設置選中的單元格的填充紋理和邊框。

try

{

       ThisApplication = new Excel.Application();

      ThisWorkbook = ThisApplication.Workbooks.Open("z:\\Book1.xls", Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing);  

       ThisApplication.DisplayAlerts = false;

       xlSheet = (Excel.Worksheet)ThisWorkbook.Worksheets.get_Item(1);

       Excel.Range range = xlSheet.get_Range("G4","H5");

       range.Value = "123";             

       Excel.Style st = ThisWorkbook.Styles.Add("PropertyBorder", Type.Missing);                                         

       range.Interior.Pattern = Excel.XlPattern.xlPatternCrissCross;

       range.Borders.Weight = 2;

       range.Borders.get_Item(XlBordersIndex.xlEdgeRight).LineStyle = Excel.XlLineStyle.xlContinuous;

       range.Borders.get_Item(XlBordersIndex.xlEdgeBottom).LineStyle = Excel.XlLineStyle.xlContinuous;

       range.Borders.get_Item(XlBordersIndex.xlEdgeTop).LineStyle = Excel.XlLineStyle.xlContinuous;

       range.Borders.get_Item(XlBordersIndex.xlDiagonalDown).LineStyle = Excel.XlLineStyle.xlLineStyleNone;

       range.Borders.get_Item(XlBordersIndex.xlDiagonalUp).LineStyle = Excel.XlLineStyle.xlLineStyleNone;

       range.Borders.get_Item(XlBordersIndex.xlInsideHorizontal).LineStyle = Excel.XlLineStyle.xlLineStyleNone;

       range.Borders.get_Item(XlBordersIndex.xlInsideVertical).LineStyle = Excel.XlLineStyle.xlLineStyleNone;

       range.Borders.get_Item(XlBordersIndex.xlEdgeLeft).LineStyle = Excel.XlLineStyle.xlDot;

  ;     range.Borders.get_Item(XlBordersIndex.xlEdgeLeft).Color = System.Drawing.ColorTranslator.ToOle(Color.Red);              

       ThisWorkbook.SaveAs("z:\\Book2.xls", Type.Missing, Type.Missing,

              Type.Missing, Type.Missing, Type.Missing, Excel.XlSaveAsAccessMode.xlNoChange,

              Type.Missing, Type.Missing, Type.Missing, Type.Missing);

}

catch (Exception ex)

{

       MessageBox.Show(ex.Message);

}

finally

{

       ThisWorkbook.Close(Type.Missing, Type.Missing, Type.Missing);

       ThisApplication.Workbooks.Close();

       ThisApplication.Quit();

       System.Runtime.InteropServices.Marshal.ReleaseComObject(ThisWorkbook);

       System.Runtime.InteropServices.Marshal.ReleaseComObject(ThisApplication);

       ThisWorkbook = null;

   ;    ThisApplication = null;

       GC.Collect();

       this.Close();

}
