我們把頁而要經常用到的一些方法封閉成類放到App_Code目錄下,這樣方便各頁面調用,主要的功能有”彈出提示”、“刷新”等方法，具體代碼如下：
using System;using System.Data;using System.Configuration;using System.Web;using System.Web.Security;using System.Web.UI;using System.Web.UI.WebControls;using System.Web.UI.WebControls.WebParts;using System.Web.UI.HtmlControls;
/**//// <summary>
/// WebHelper 的摘要說明/// </summary>public class WebHelper...{ public WebHelper()
...{ // // TODO: 在此處添加構造函數邏輯 //
} public static void Alert(string sMessage) ...{ HttpContext.Current.Response.Write("<script>alert(''" + sMessage + "'');</script>"); } public static void AlertAndRefresh(string sMessage) ...{ HttpContext.Current.Response.Write("<script>alert(''" + sMessage + "'');location.href=location.href</script>"); } public static void Refresh() ...{ HttpContext.Current.Response.Write("<script>location.href=location.href</script>"); } public static void AlertAndRedirect(string sMessage, stringsURL) ...{ HttpContext.Current.Response.Write("<script>alert(''" + sMessage + "'');location.href=''" + sURL + "''</script>"); } public static void AlertAndClose(string sMessage) ...{ HttpContext.Current.Response.Write("<script>alert(''" + sMessage + "'');window.opener=null;window.close()</script>"); } public static void ExecJS(string sMessage) ...{ HttpContext.Current.Response.Write("<script>" + sMessage + "</script>"); } public static string GetPcAccount()...{ return HttpContext.Current.User.Identity.Name; } public static string GetCurrentUser() ...{ string strUserId = HttpContext.Current.Session["UserId"] == null ?
