推荐答案

private void btnExportExcel_Click()
{
    Response.Clear();
    Response.Buffer = true;

    Response.AddHeader("content-disposition",
     "attachment;filename=MyData.xls");
    Response.Charset = "";
    Response.ContentType = "application/vnd.ms-excel";
    StringWriter sw = new StringWriter();
    HtmlTextWriter hw = new HtmlTextWriter(sw);

    GridView1.AllowPaging = false;
    GridView1.DataBind();

    GridView1.HeaderRow.Style.Add("background-color", "#FFFFFF");
    GridView1.HeaderRow.Cells[0].Style.Add("background-color", "green");
    GridView1.HeaderRow.Cells[1].Style.Add("background-color", "green");

    GridView1.HeaderRow.Cells[0].Visible = True;
    GridView1.HeaderRow.Cells[1].Visible = False;

    for (int i = 0; i < GridView1.Rows.Count;i++ )
    {
        GridViewRow row = GridView1.Rows[i];
        row.Cells[0].Visible = True;
        row.Cells[1].Visible = False;
        row.BackColor = System.Drawing.Color.White;
        row.Attributes.Add("class", "textmode");
    }

    GridView1.RenderControl(hw);
    string style = @"<style> .textmode { mso-number-format:\@; } </style>";
    Response.Write(style);
    Response.Output.Write(sw.ToString());
    Response.End();
}

这里我有硬编码（真/假），如果你需要它是动态的那么你的复选框到列的一侧和复制商店的更改它在视图中。稍后您可以从查看状态获取已检查的列。
