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();

}
