C#操作Excell常用方法

这是在博客园看的文章，写的很好，所以转一下，方便自己以后用到的时候可以随时查看。

操作range类需要在项目中引用两个dll，不然点不出来，分别是：

microsoft office XX.0 Object Library

microsoft excelXX.0 Object Library

----------------------------------------------------------------------分割线

range.NumberFormatLocal = "@";     //设置单元格格式为文本


range = (Range)worksheet.get_Range("A1", "E1");     //获取Excel多个单元格区域：本例做为Excel表头

range.Merge(0);     //单元格合并动作

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
