打开nettcpbinding WCF服务时无效的opertion异常 [英] Invalid opertion exception when I open a nettcpbinding WCF service

问题描述

大家早上好，



我正在开发一个托管WCF服务的Windows应用程序。

我正在使用NetTcpBinding，当我尝试打开一个连接时，会抛出一条带有此消息的InvalidOpenException：

ContractDescption'IHyperisCommonService'不包含任何操作;合同必须至少包含一项操作。

但在我的情况下，我的界面如下所示：

Good morning everyone,

I’m working on a windows application that is hosting a WCF service.
I’m using NetTcpBinding and when I try to open a connection an InvalidOpenException is thrown with this message:
ContractDescption 'IHyperisCommonService' contains no operation; a contract must contain at least an operation.
But in my case my interface looks like this:

[ServiceContract]
public interface IHyperisCommonService
{
   Guid IsOnLine(Guid message);
}

最糟糕的是我已经将这个界面与另一个应用程序一起使用了，我没有遇到问题。



这里是我使用的代码：

The worst thing is I already use this interface with another application and I don’t get the problem.

Here the code I use:

ServiceHost serviceHostStatus = new ServiceHost(typeof(Hyperis.Common.HyperisCommonService));
NetTcpBinding serviceHostBinding = new NetTcpBinding();
serviceHostStatus.AddServiceEndpoint(typeof(Hyperis.Common.IHyperisCommonService), serviceHostBinding, new Uri("net.tcp://localhost:5000/HyperisCommonService"));
serviceHostStatus.Open();

有人有线索吗？



感谢您的帮助。





我的尝试：



我已经在同一台机器上使用此WCF服务与之前的应用程序。

Anybody have a clue ?

Thanks for helping.


What I have tried:

I already use this WCF service with a previous application on the same machine.

推荐答案

我用Google搜索了您的错误消息并找到了这个



WCF错误：ContractDescription'......'没有操作;合同必须至少有一项操作。 [ ^ ]



请在询问谷歌搜索任何错误信息之前进行基础研究。

I googled your error message and found this

WCF error : ContractDescription '...' has zero operations; a contract must have at least one operation.[^]

Please do basic research before asking a question such as googling any error messages you get.
