WCF服务未正确调用(超时问题) [英] WCF Service not invoking properly (Timeout issue)

问题描述

大家好，

我编写了C#WCF服务，该服务可扫描路径并返回所有文件.现在，如果我扫描相对较小的内容，例如我的文档"，它就可以正常工作.但是，当我尝试扫描C:\驱动器时，在WCF测试客户端中出现以下错误:

Hi all,

Ive written a C# WCF Service that scans a path and returns all the files. Now it works fine if I scan something relatively small, for example - My Documents. But when I try to scan the C:\ drive I get the following error in the WCF Test Client:

The request channel timed out while waiting for a reply after 00:00:59.9844000. Increase the timeout value passed to the call to Request or increase the SendTimeout value on the Binding. The time allotted to this operation may have been a portion of a longer timeout.

现在，如果我在代码中使用断点，则可以看到代码成功，似乎响应已超时.我已经为超时等修改了配置文件中的绑定设置，但似乎无法解决它.

这是我进行的WCF服务的首次尝试，所以请放轻松！

任何建议将不胜感激.

谢谢，

Jib

Now if I use breakpoints in the code I can see that the code is successful, it just seems that the response is timing out. I''ve amended the binding settings in the config file for timeouts etc, but I don''t seem to be able to resolve it.

This is the first attempt at a WCF service I''ve made so please go easy on me!

Any suggestions would be thoroughly appreciated.

Thanks,

Jib

在大量阅读和更改设置之后，最终成为客户端端点配置.做到了:

Well after a lot of reading and changing settings it ended up being the client side endpoint configuration. This did it:

private void ConfigureClientEndPoint(ServiceEndpoint endPoint)
        {
            foreach (OperationDescription operation in 
                     endPoint.Contract.Operations)
            {
                DataContractSerializerOperationBehavior dataContractBehavior = 
                operation.Behaviors.Find<DataContractSerializerOperationBehavior>();
                if (dataContractBehavior != null)
                {
                    dataContractBehavior.MaxItemsInObjectGraph = 2147483647;
                }
            }
        }
