}
2.单元格样式设置
Excel.Range r =mySheet.get_Range(mySheet.Cells[1,1],mySheet.Cells[DT.Rows.Count + 2,DT.Columns.Count - 3]); r.NumberFormat="@"; //设置单元格格式为文本类型，文本类型可设置上下标 r.NumberForma="0.00_ "//设置单元格格式为数值类型，小数点后2位 r.NumberForma="￥#,##0.00;￥-#,##0.00"//设设置单元格格式为货币类型，小数点后2位 r.NumberForma=_"_ ￥*#,##0.00_;_ ￥*-#,##0.00_ ;_ ￥*""-""??_;_ @_ "//置单元格格式为会计专用类型，小数点后2位 r.NumberForma="yyyy-m-d"//设置单元格格式为日期类型 r.NumberForma="[$-F400]h:mm:ss AM/PM"//设置单元格格式为时间类型 r.NumberForma="0.00%"//设置单元格格式为百分比类型，小数点后2位 r.NumberForma="# ?/?"设置单元格格式为分数类型，分母为一位数 r.NumberForma="0.00E+00"//设置单元格格式为科学技术类型，小数位数为2 r.NumberForma="000000"//设置单元格格式为特殊类型 B、上下标格式的控制； mySheet.get_Range(mySheet.Cells[i+3, DT.Columns.Count - 3],mySheet.Cells[i + 3, DT.Columns.Count -3]).get_Characters(a.Length+ 1,b.Length).Font.Subscript =true;//控制输出样式为下标 mySheet.get_Range(mySheet.Cells[i+3, DT.Columns.Count - 3],mySheet.Cells[i + 3, DT.Columns.Count-3]).get_Characters(a.Length + b.Length+ 1, c.Length).Font.Superscript =true; //控制输出样式为上标 C、单元格水平垂直对齐方式； //单元格水平，垂直居中 r.HorizontalAlignment=Excel.XlHAlign.xlHAlignCenter; r.VerticalAlignment=Excel.XlVAlign.xlVAlignCenter; 上面代码中，枚举XLHAlign的值还有： // 右对齐 xlHAlignRight, // 左对齐. xlHAlignLeft, // 两端对齐. xlHAlignJustify, // 分散对齐(缩进) xlHAlignDistributed, // 居中对齐 xlHAlignCenter, // 依照数据类型对齐,常规 xlHAlignGeneral, // 填充 xlHAlignFill, // 跨列对齐. xlHAlignCenterAcrossSelection=7, 枚举XLVAlign的值还有： // 靠上对齐 xlVAlignTop, //两端对齐. xlVAlignJustify=-4130, //分散对齐. xlVAlignDistributed, //居中对齐. xlVAlignCenter, //靠下对齐. xlVAlignBottom=-4107, D、 单元格边框设置； //设置边框 Excel.Range r =mySheet.get_Range(mySheet.Cells[1,1],mySheet.Cells[DT.Rows.Count + 2,DT.Columns.Count - 3]); r.Borders.LineStyle=Excel.XlLineStyle.xlContinuous; 枚举XlLineStyle中还有下面线形： //没边框线 xlLineStyleNone, //双线. xlDouble, //点状线. xlDot, //虚线. xlDash, //连续线. xlContinuous, //点线交互型 xlDashDot, //两点一线型 xlDashDotDot, //斜线. xlSlantDashDot, E、单元格合并 用get_Range方法获取要合并的单元格，再设置MergeCells属性的值进行合并。 代码： //合并单元格 myExcel.get_Range(myExcel.Cells[1,1],myExcel.Cells[1,4]).MergeCells =true; F、字体设置 先用get_Range方法选中要设置字体的某个单元格或者或者直接用get_Characters方法直接选中要设置的字符进行设置； 代码： //加粗字体 myExcel.get_Range(myExcel.Cells[1,1],myExcel.Cells[1,1]).Font.Bold =true; //设置字体大小 myExcel.get_Range(myExcel.Cells[1,1],myExcel.Cells[1,1]).Font.Size=16; //设置字体的颜色 myExcel.get_Range(myExcel.Cells[1,1],myExcel.Cells[1,1]).Font.ColorIndex = 3; //设置字体 myExcel.get_Range(myExcel.Cells[1,1],myExcel.Cells[1,1]).Font.Name ="隶书"; //设置成斜体 myExcel.get_Range(myExcel.Cells[1,1],myExcel.Cells[1,1]).Font.Italic =true; //设置下划线 myExcel.get_Range(myExcel.Cells[1,1],myExcel.Cells[1,1]).Font.Underline =true; G、冻结行列 用get_Range方法获取单元格，再设置其Freezepanes属性为true，就把该单元格右上方的行和列都冻结了，取消冻结将其值设为false即可。 //冻结行列 myExcel.get_Range(myExcel.Cells[3,1],myExcel.Cells[3,1]).Activate(); myExcel.ActiveWindow.FreezePanes=true; H、 公式输入栏的隐藏 //设置是否显示Excel公式输入栏，默认为true myExcel.DisplayFormulaBar=false; I、 列标题与行标题的隐藏 //设置是否显示行和列的标题，默认为true myExcel.ActiveWindow.DisplayHeadings=false; J、网格的隐藏 //设置是否显示网格，默认为true myExcel.ActiveWindow.DisplayGridlines=false; K、 水平、垂直滚动条的隐藏 //设置是否显示水平滚动条 myExcel.ActiveWindow.DisplayHorizontalScrollBar=false; //设置是否显示垂直滚动条 myExcel.ActiveWindow.DisplayVerticalScrollBar=false; L、页的隐藏Sheet //设置是否显示Sheet页 myExcel.ActiveWindow.DisplayWorkbookTabs=false; M、 电子表格外观控制： Sheet.DisplayToolbar= false;//是否显示工具栏默认值为 true Sheet.DisplayOfficeLogo= false;// 取消显示Office图标 Sheet.DisplayColumnHeadings= false;// 是否显示列标题，默认是true Sheet.DisplayRowHeadings= false;// 是否显示行标题，默认是true Sheet.DisplayHorizontalScrollBar= false;// 是否显示水平滚动条，默认为true Sheet.DisplayVerticalScrollBar= false;// 是否显示垂直滚动条，默认为true Sheet.DisplayGridlines= false;// 电子表格是否显示网格，默认为true for (int i = 1; i < DT.Columns.Count- 2; i += 2) { Sheet.get_Range(Sheet.Rows.Cells[i,1],Sheet.Rows.Cells[i, DT.Columns.Count - 3]).Interior.set_ColorIndex(2); //设置行的颜色 } worksheet.Cells[1, 1]= "Excel单元格赋值";//Excel单元格赋值 range.Font.Size = 15; //设置字体大小 range.Font.Underline=true; //设置字体是否有下划线 range.Font.Name="黑体";设置字体的种类 range.HorizontalAlignment=XlHAlign.xlHAlignCenter; //设置字体在单元格内的对其方式 range.ColumnWidth=15; //设置单元格的宽度 range.Cells.Interior.Color=System.Drawing.Color.FromArgb(255,204,153).ToArgb();//设置单元格的背景色 range.Borders.LineStyle=1; //设置单元格边框的粗细 range.BorderAround(XlLineStyle.xlContinuous,XlBorderWeight.xlThick,XlColorIndex.xlColorIndexAutomatic,System.Drawing.Color.Black.ToArgb());//给单元格加边框 range.Borders.get_Item(Microsoft.Office.Interop.Excel.XlBordersIndex.xlEdgeTop).LineStyle=Microsoft.Office.Interop.Excel.XlLineStyle.xlLineStyleNone;//设置单元格上边框为无边框 range.EntireColumn.AutoFit(); //自动调整列宽 Range.HorizontalAlignment= xlCenter; // 文本水平居中方式 Range.VerticalAlignment= xlCenter //文本垂直居中方式 Range.WrapText=true; //文本自动换行 Range.Interior.ColorIndex=39; //填充颜色为淡紫色 Range.Font.Color=clBlue; //字体颜色 xlsApp.DisplayAlerts=false; //保存Excel的时候，不弹出是否保存的窗口直接进行保存 向Excel中填充数据，并保存为临时文件 Excel.ApplicationmyExcel =newExcel.Application(); //打开模板文件 myExcel.Application.Workbooks.Open(mode.FullName,missing,missing,missing, missing, missing, missing, missing, missing,missing, missing,missing,missing, missing, missing); //选中有数据的Cells Excel.WorkbookmyBook = myExcel.Workbooks[1]; Excel.WorksheetmySheet = (Excel.Worksheet)myBook.Worksheets[1]; Excel.Ranger = mySheet.get_Range(mySheet.Cells[1,1],mySheet.Cells[DT.Rows.Count + 2,DT.Columns.Count - 3]); r.Select(); //不单独显示Excel，最后在IE中显示 myExcel.Visible=false; //第一行为报表的标题 myExcel.Cells[1,1]= "用模板导出的报表"; //逐行写入数据，数组中第一行为报表的列标题 for (int i = 0; i3; i++) { myExcel.Cells[2,1+ i] =DT.Columns[i].Caption; ; } //在当前目录下指定一个临时文件 string FileName =Server.MapPath("~")+"""Temp.xls"; if (File.Exists(FileName)) { File.Delete(FileName); } myExcel.Save(FileName); mySheet.Cells.Clear(); //设置不出现保存提示框 myBook.Saved=true; myExcel.Application.Workbooks.Close();
