WCF c#.net中的EndPointNotFoundException [英] EndPointNotFoundException in WCF c#.net

问题描述

你好

我在WCF c#.net中有EndPointNotFoundException.消息的粗​​体部分出现异常.服务器和客户端之间通过预定义中动态生成的代理之间的连接.但是当服务器调用客户端功能时，就会发生此异常.

hello

i have EndPointNotFoundException in WCF c#.net. exception occurs in the bold area of message. where the connection between the server and clients through dynamically generated proxies in pre define. but when the server call the client fucntion then this exception occurs.

推荐答案

未找到端点异常意味着它所说的内容.客户端找不到指定的终点.确保-

1.终点地址正确.
2.服务器已启动并且正在运行，并且您的WCF服务可用
3.如果您的服务已更新，则端点mcght已更改.确保您具有指向最新更新服务的代理.您可以尝试重新创建一个新的代理，然后重试.
4.您可能还想研究客户的特权.也就是说，您的客户应具有足够的特权来访问您的服务.

希望这会有所帮助.

End Point not found exception means exactly what it says. The client cannot find the end point that is specified. Make sure -

1. The end point address is correct.
2. The server is up and running and your WCF service is available
3. The endpoint mcght have changed if your service was updated. Make sure you have the proxy pointing to the latest updated service. You can try and recreate a new proxy and try again.
4. You might also want to look into the privilege of your client. i.e. your client should have enough privilege to access your service.

Hope this helps.
