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:
1 range.NumberFormatLocal = "@"; //设置单元格格式为文本 2 ange.get_Range("B1","B"+dataGridView2.RowCount+1).NumberFormat = "yyyy-m-d hh:mm:ss"; //时间格式的设置 3 range = (Range)worksheet.get_Range("A1", "E1"); //获取Excel多个单元格区域：本例做为Excel表头 4 range.Merge(0); //单元格合并动作 5 worksheet.Cells[1, 1] = "Excel单元格赋值"; //Excel单元格赋值 6 range.Font.Size = 15; //设置字体大小 7 range.Font.Underline=true; //设置字体是否有下划线 8 range.Font.Name="黑体"; 设置字体的种类 9 range.HorizontalAlignment=XlHAlign.xlHAlignCenter; //设置字体在单元格内的对其方式 10 range.ColumnWidth=15; //设置单元格的宽度 11 range.Cells.Interior.Color=System.Drawing.Color.FromArgb(255,204,153).ToArgb(); //设置单元格的背景色 12 range.Borders.LineStyle=1; //设置单元格边框的粗细 13 range.BorderAround(XlLineStyle.xlContinuous,XlBorderWeight.xlThick,XlColorIndex.xlColorIndexAutomatic,System.Drawing.Color.Black.ToArgb()); //给单元格加边框 14 range.EntireColumn.AutoFit(); //自动调整列宽 15 Range.HorizontalAlignment= xlCenter; // 文本水平居中方式 16 Range.VerticalAlignment= xlCenter //文本垂直居中方式 17 Range.WrapText=true; //文本自动换行 18 Range.Interior.ColorIndex=39; //填充颜色为淡紫色 19 Range.Font.Color=clBlue; //字体颜色 20 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 21 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：
