在用Excel作报表的时候，可能需要操作单元格的边框和填充颜色和纹理等操作，下面的代码说明如何设置选中的单元格的填充纹理和边框

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();
}
