[转]Excel导出及数据格式化处理

 1 public void ToExcel(System.Web.UI.Control ctl, string FileName)
 2         {
 3             HttpContext.Current.Response.Charset = "UTF-8";
 4             HttpContext.Current.Response.ContentEncoding = System.Text.Encoding.Default;
 5             HttpContext.Current.Response.ContentType = "application/ms-excel";
 6             HttpContext.Current.Response.AppendHeader("Content-Disposition", "attachment;filename=" + "" + FileName + ".xls");
 7             ctl.Page.EnableViewState = false;
 8             System.IO.StringWriter tw = new System.IO.StringWriter();
 9             HtmlTextWriter hw = new HtmlTextWriter(tw);
10             ctl.RenderControl(hw);
11             HttpContext.Current.Response.Write(tw.ToString());
12             HttpContext.Current.Response.End();
13         }
14         public override void VerifyRenderingInServerForm(Control control)
15         {
16             //base.VerifyRenderingInServerForm(control);
17         }
18         protected void myGridView_RowDataBound(object sender, GridViewRowEventArgs e)
19         {
20             if (e.Row.RowType == DataControlRowType.DataRow)
21             {
22                 //e.Row.Cells[0].Attributes.Add("style", "vnd.ms-excel.numberformat:@");//这里是将要导出到execl里的第一列格式化为字符类型。
23                 //e.Row.Cells[3].Attributes.Add("style", "vnd.ms-excel.numberformat:¥#,###.00");//这里是格式化为货币类型。
24                 e.Row.Cells[4].Attributes.Add("style", "vnd.ms-excel.numberformat:@");
25                 //1) 文本:vnd.ms-excel.numberformat:@
26                 //2) 日期:vnd.ms-excel.numberformat:yyyy/mm/dd
27                 //3) 数字:vnd.ms-excel.numberformat:#,##0.00
28                 //4) 货币:vnd.ms-excel.numberformat:¥#,##0.00
29                 //5) 百分比:vnd.ms-excel.numberformat: #0.00%
30             }
31         }

以上只是部分格式,还有更多,可以打开Excel查看,如下图:

图一、Excel其它格式

由于我需要导出一串类似于"201304110093"这样的字符串,但导出Excel后,其格式竟然为"2.01304E+11",实在太无耻了~,于是我在Excel中一通乱试,终于发现,把储存格式调为上图那个自定义的"0"格式即一切正常,所以,嘿嘿,在代码中果断加入:

1 protected void gvAboveFiveList_RowDataBound(object sender, GridViewRowEventArgs e)
2     {
3         if (e.Row.RowType == DataControlRowType.DataRow)
4         {
5             //讓輸出的數字以自定義的0格式輸出
6             e.Row.Cells[0].Attributes.Add("style", "vnd.ms-excel.numberformat:0");
7         }
8     }

好了,收工啦~~
