要导出页的前台：
<asp:Button runat="server" ID="btnExport" Text="导出" CssClass="button_sm7"
onclick="btnExport_Click" />
后台：
protected void btnSearch_Click(object sender, EventArgs e)
{
Response.Redirect("Export.aspx?uname=" + txtUNameS.Text + "&dep=" + this.ddlDepS.SelectedValue
+ "&class=" + this.ddlClassS.SelectedValue + "&iyear=" + this.ddlYearS.SelectedValue);
}
