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。
