使用C#和Excel进行报表开发（五）－操作单元格边框和颜色

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(); }
