DataTable导出Execl
代码太简单，我们直接看代码。
复制代码 代码如下:
protected void btnPrint_Click(object sender, EventArgs e)
{
string strPath = "MFOut" + DateTime.Now.ToString("yyyymmddhhmmssfff") + ".xls";
DataGrid dg = new DataGrid();
dg.DataSource = dtMain;
dg.DataBind();
Response.Clear();
Response.AddHeader("content-disposition", "attachment;filename=" + strPath + "");
Response.Charset = "gb2312";
Response.ContentEncoding = System.Text.Encoding.UTF8;//不设置会有乱码
Response.ContentType = "application/vnd.xls";
System.IO.StringWriter stringWrite = new System.IO.StringWriter();
System.Web.UI.HtmlTextWriter htmlWrite = new HtmlTextWriter(stringWrite);
dg.RenderControl(htmlWrite);
Response.Write(stringWrite.ToString());
Response.End();
}
public override void VerifyRenderingInServerForm(Control control)
{
//这个方法不能删除掉 导出时要用到，不然会报错：
//类型“GridView”的控件“ctl00_ContentPlaceHolder1_GridView1”必须放在具有 runat=server 的窗体标记内
}
