WCF和IIS宿主的ASP.NET 共享会话

yunvn

　　1. 建立WCF工程
using System;
using System.Collections.Generic;
using System.Linq;
using System.Runtime.Serialization;
using System.ServiceModel;
using System.Text;
using System.Web;
using System.ServiceModel.Activation;
namespace WCFASPSession
{
[AspNetCompatibilityRequirements(RequirementsMode =
AspNetCompatibilityRequirementsMode.Allowed)]
public class Service1 : IService1
{
public int Add(int value)
{
int result = GetResult() + value;
HttpContext.Current.Session["Result"] = result;
return result;
}
public int GetResult()
{
if (HttpContext.Current.Session["Result"] == null)
{
HttpContext.Current.Session["Result"] = 0;
}
return (int)HttpContext.Current.Session["Result"];
}
}
}
　　2. 在web工程里建一个.svc文件

<%@ ServiceHost Language=&quot;C#&quot; Debug=&quot;true&quot; Service=&quot;WCFASPSession.Service1&quot;  %>
　　3. 修改web.config
　　主要是添加<serviceHostingEnvironment aspNetCompatibilityEnabled=&quot;true&quot;></serviceHostingEnvironment> ，还有allwoCookies一定要设为true.
