asp.net将Gridview导出Excel(身份证号的正确显示)

GridView导出Excel的代码如下：

if (this.GridView1.Rows.Count != 0)
            {
                HttpContext.Current.Response.Clear();
                HttpContext.Current.Response.AddHeader("content-disposition", "attachment;filename=" + DateTime.Now.ToString("yyyyMMddHHmmss") + ".xls");     //这里是用日期做名称
                HttpContext.Current.Response.Charset = "utf-8";
                HttpContext.Current.Response.ContentType = "application/excel";
                System.IO.StringWriter stringWrite = new System.IO.StringWriter();
                System.Web.UI.HtmlTextWriter htmlWrite = new HtmlTextWriter(stringWrite);
                this.GridView1.AllowPaging = false;                 //GridView不启用分页
                GridView1.RenderControl(htmlWrite);
                HttpContext.Current.Response.Write(stringWrite.ToString());
            }

如果你的 GridView 中有 【身份证号】 那你就要注意喽！将身份证号那一列设置为以下这种格式，就OK拉！

for (int i = 1; i <= GridView1.Rows.Count; i++)
        {
            GridView1.Rows[i - 1].Cells[3].Attributes.Add("style", "vnd.ms-excel.numberformat:@");
            GridView1.Rows[i - 1].Cells[18].Attributes.Add("style", "vnd.ms-excel.numberformat:@");
        }

我自己写的

   private void ExportDataGrid(string FileType, string FileName)
    {
        Response.Charset = "UTF-8";
        Response.ContentEncoding = System.Text.Encoding.GetEncoding("UTF-8");

        Response.AppendHeader("Content-Disposition", "attachment;filename=" + FileName);
        Response.ContentType = FileType;
        this.EnableViewState = false;
        StringWriter tw = new StringWriter();
        HtmlTextWriter hw = new HtmlTextWriter(tw);
        mydiv.RenderControl(hw);
        //用Repeater控件中的RenderControl()函数
        Response.Write(tw.ToString());
        Response.End();
    }

    //protected void printzjs_Click(object sender, EventArgs e)
    //{
    //    this.Repeater2.DataSource = new zjsUserService().GetTable("", "where Audit=1 ", " order by ID asc");
    //    this.Repeater2.DataBind();
    //    ExportDataGrid("application/ms-word", "zjslist.xls");   //调用导出Word函数

    //}
    protected void printzjs_Click(object sender, EventArgs e)
    {
    
        this.GridView1.DataSource = new zjsUserService().GetTable("", "where Audit=1 ", " order by ID asc");
        this.GridView1.DataBind();
        for (int i = 1; i <= GridView1.Rows.Count; i++)
        {
            GridView1.Rows[i - 1].Cells[0].Attributes.Add("style", "vnd.ms-excel.numberformat:@");
          
        }

        ExportDataGrid("application/ms-word", "zjslist.xls");   //调用导出Word函数

    }
