请尝试一下.....

公共无效ExportToExcel(DataTable dt)
{
如果(dt.Rows.Count> 0)
{
字符串文件名="ExcelFileName.xls"；
System.IO.StringWriter tw =新的System.IO.StringWriter();
System.Web.UI.HtmlTextWriter hw =新的System.Web.UI.HtmlTextWriter(tw);
DataGrid dgGrid = new DataGrid();
dgGrid.DataSource = dt;
dgGrid.DataBind();

//获取控件的HTML.
dgGrid.RenderControl(hw);
//将HTML写回到浏览器.
//Response.ContentType = application/vnd.ms-excel;
Response.ContentType ="application/vnd.ms-excel";
Response.AppendHeader("Content-Disposition"，"attachment; filename =" + filename +");
this.EnableViewState = false;
Response.Write(tw.ToString());
Response.End();
}
}

受保护的无效btnSave_Click(对象发送者，EventArgs e)
{
ExportToExcel((DataTable)ViewState ["gvMobile"]);
}

公共重写void VerifyRenderingInServerForm(Control control)

{

}

Pls try it.....

public void ExportToExcel(DataTable dt)
{
if (dt.Rows.Count > 0)
{
string filename = "ExcelFileName.xls";
System.IO.StringWriter tw = new System.IO.StringWriter();
System.Web.UI.HtmlTextWriter hw = new System.Web.UI.HtmlTextWriter(tw);
DataGrid dgGrid = new DataGrid();
dgGrid.DataSource = dt;
dgGrid.DataBind();

//Get the HTML for the control.
dgGrid.RenderControl(hw);
//Write the HTML back to the browser.
//Response.ContentType = application/vnd.ms-excel;
Response.ContentType = "application/vnd.ms-excel";
Response.AppendHeader("Content-Disposition", "attachment; filename=" + filename + "");
this.EnableViewState = false;
Response.Write(tw.ToString());
Response.End();
}
}

protected void btnSave_Click(object sender, EventArgs e)
{
ExportToExcel((DataTable)ViewState["gvMobile"]);
}

public override void VerifyRenderingInServerForm(Control control)

{

}
