在c#中设置Excel格式

生成excel的时候有时候需要设置单元格的一些属性,可以参考一下:

 range.NumberFormatLocal = "@";     //设置单元格格式为文本
 ange.get_Range("B1","B"+dataGridView2.RowCount+).NumberFormat = "yyyy-m-d hh:mm:ss"; //时间格式的设置
 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();     //单元格合并动作
 worksheet.Cells[, ] = "Excel单元格赋值";     //Excel单元格赋值
 range.Font.Size = ;     //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=;     //设置单元格的宽度
 range.Cells.Interior.Color=System.Drawing.Color.FromArgb(,,).ToArgb();     //设置单元格的背景色
 range.Borders.LineStyle=;     //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.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=;     //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
 workbook.SaveCopyAs(temp);///填入完信息之后另存到路径及文件名字

注：要添加COM组件 Microsoft Excel 11.0 Object Library 引用。
具体代码如下：
