问题描述

限时送ChatGPT账号..

我有一个 c# 应用程序，它使用 OperationContextScope scope = new OperationContextScope(i.InnerChannel); 调用 wcf 服务；

I have a c# app that calls a wcf serivce using OperationContextScope scope = new OperationContextScope(i.InnerChannel);

我需要让连接保持打开状态，因此我无法使用 Using 语句处理 OperationContextScope.但是，在查看内存分析器时，我看到了数百个 OperationContextScope.我需要处理范围，但是当我调用 .Dispose() 时，我收到一条错误消息，说它不正常.我不知道为什么我不能处置范围.

I need to leave the connections open so I cannot dispose the OperationContextScope with the Using statement. However when looking at the memory profiler I am seeing hundreds of OperationContextScope's. I need to dispose the scope but when I call .Dispose() I get an error saying its out of order. I have no idea why I cannot dispose the scope.

有谁知道如何正确处理 OperationContextScope ?以下是我的部分代码.

Does anyone know how to correctly dispose OperationContextScope ? Below is part of my code.

                BasicHttpBinding wsbinding = null;                  
                 OperationContextScope scope  = null;

                    wsbinding = new BasicHttpBinding(BasicHttpSecurityMode.None);
                    wsbinding.MaxBufferSize = 2147483647;
                    wsbinding.MaxReceivedMessageSize = 2147483647;
                    wsbinding.Name = "BasicHttpBinding_Iretail";



                i = new IretailClient(wsbinding, new EndpointAddress(commonStuff.EndpointAddress));

                scope = new OperationContextScope(i.InnerChannel);

推荐答案

来自 http://msdn.microsoft/en-us/library/system.servicemodel.operationcontextscope.aspx:

创建 OperationContextScope 时，当前 OperationContext被存储并且新的 OperationContext 成为由目前的财产.当 OperationContextScope 被释放时，原始 OperationContext 恢复.

When an OperationContextScope is created, the current OperationContext is stored and the new OperationContext becomes the one returned by the Current property. When the OperationContextScope is disposed, the original OperationContext is restored.

显然，它们必须按照创建时的相反顺序进行处理.

Clearly, they must be disposed in the reverse order they were created.

scope.Dispose();
