[mangchao330688]

怎么把gridview里的数据导出来呢 要Excel格式的。希望能是一个公用的方法 因为有很多地方需要调用这个烦方法。

  /// <summary>
        /// 导出Excel
        /// </summary>
        /// <param name="sender"></param>
        /// <param name="e"></param>
        protected void btnExcel_Click(object sender, EventArgs e)
        {
            Response.Clear();
            System.Web.HttpContext curContext = System.Web.HttpContext.Current;
            Response.AddHeader("content-disposition",
            "attachment;filename=instimestock.xls");
            Response.Charset = "utf-8";
            Response.ContentEncoding = System.Text.Encoding.GetEncoding("GB2312"); 
            Response.ContentType = "application/vnd.xls";
            System.IO.StringWriter stringWrite = new System.IO.StringWriter();
            System.Web.UI.HtmlTextWriter htmlWrite = new HtmlTextWriter(stringWrite);
            //写到Excel的数据不用分页
            //BindData();
            gridviewName.RenderControl(htmlWrite);
            Response.Write(stringWrite.ToString());//向客户端写数据
            Response.End();
}

 //这个方法不写的话可能报错类型“GridView”的控件“GridView1”必须放在具有 runat=server 的窗体标记内。
    public override void VerifyRenderingInServerForm(Control control)
    {
        // Confirms that an HtmlForm control is rendered for
    }

要不要给你发demo？？ 我都是这样用的。

这个满足你的需求

private void CreateExcel(DataTable dt, string fileName)
{

HttpResponse resp;
resp = Page.Response;
resp.ContentEncoding = System.Text.Encoding.GetEncoding("GB2312");
resp.AppendHeader("Content-Disposition", "attachment;filename=" + fileName);
string colHeaders = "", ls_item = "";

////定义表对象与行对象，同时用DataSet对其值进行初始化
//DataTable dt = ds.Tables[0];
DataRow[] myRow = dt.Select();//可以类似dt.Select("id>10")之形式达到数据筛选目的
//取得数据表各列标题，各标题之间以t分割，最后一个列标题后加回车符
for (int i = 0; i < dt.Columns.Count; i++)
{
if (i == (dt.Columns.Count - 1))//最后一列，加n
{
colHeaders += dt.Columns[i].Caption.ToString() + "\n";
}
else
{
colHeaders += dt.Columns[i].Caption.ToString() + "\t";
}
}
resp.Write(colHeaders);
//向HTTP输出流中写入取得的数据信息

//逐行处理数据
foreach (DataRow row in myRow)
{
//当前行数据写入HTTP输出流，并且置空ls_item以便下行数据
for (int i = 0; i < dt.Columns.Count; i++)
{
if (i == (dt.Columns.Count - 1))//最后一列，加n
{
ls_item += row[i].ToString() + "\n";
}
else
{
ls_item += row[i].ToString() + "\t";
}

}
resp.Write(ls_item);
ls_item = "";

}
resp.End();
}
