在使用WCF会话 [英] Using the Session in WCF

问题描述

下面就是我试图做使用会话在我的WCF应用程序：

Here's what I'm trying to do to use the Session in my WCF application:

 System.Guid guid = System.Guid.NewGuid();
 string id = guid.ToString();
 HttpContext.Current.Session[id] = "AnyThing";

但我收到此错误消息：

But I'm receiving this error message:

对象引用未设置为对象的实例。

Object Reference not set to instance of Object.

这是使用正确的方法会话在WCF应用程序？ ？还是有另一种方式来储存在WCF数据

Is this the right approach for using the Session in a WCF application? Or is there another way to store data within WCF?

推荐答案

您将需要启用的 ASP.NET兼容模式

的web.config

web.config

<system.serviceModel>
  <serviceHostingEnvironment aspNetCompatibilityEnabled="true" />
</system.serviceModel>

您WCF服务需要具备的 AspNetCompatibilityRequirementsAttribute 的设置要求或允许。

Your WCF services need to have the AspNetCompatibilityRequirementsAttribute set to Required or Allowed.

[AspNetCompatibilityRequirements(RequirementsMode = AspNetCompatibilityRequirementsMode.Required)]
public class CalculatorService : ICalculatorSession
