Question

wangdequan,  global.asax 怎么用？具体点呀!

Answer 1

在global.asax 中写的是全局性函数，全是静态函数，例如，Start Kit的global.asax.cs：
using System;
using System.Collections;
using System.ComponentModel;
using System.Web;
using System.Security;
using System.Security.Principal;
using System.Web.Security;
using System.Data.SqlClient;
using System.Threading;
using System.Globalization;namespace ASPNET.StarterKit.Portal {    public class Global : System.Web.HttpApplication {        //*********************************************************************

        // obtains the current tabIndex and TabId from the querystring of the 
        // request -- and then obtains the configuration necessary to process
        // and render the request.
        //
        // This portal configuration is stored within the application's "Context"

            if (Request.Params["tabindex"] != null) {               
                tabIndex = Int32.Parse(Request.Params["tabindex"]);
            }
                        
            // Get TabID from querystring
        
            if (Request.Params["tabid"] != null) {              
                tabId = Int32.Parse(Request.Params["tabid"]);
            } // Build and add the PortalSettings object to the current Context

Answer 3

没有看明白，你直接写一个数据类，实例化对象放到Session里面不就可以了？然后从Session里面取对象出来，想怎么用就怎么用拉。
