一台服务器上出现WCF错误,但另一台服务器上没有:套接字连接已中止

wcf sockets .net c#

CalculatorServiceReference.AnswerResultClient client = new CalculatorServiceReference.AnswerResultClient("NetTcpBinding_IAnswerResult");
rtn = client.ServiceUpdate(org_int, sData); // ERROR HERE
client.Close();

在服务器中:

public interface IAnswerResult
{
    [OperationContract]
    bool ServiceUpdate(string org_int, string delimitedString);
}
public bool ServiceUpdate(string org_int, string delimitedString)
{
...
}

我有一个相同的服务器和服务,工作正常,我似乎找不到任何区别。错误会立即发生,因此看起来不是超时问题。

尝试为绑定配置“receiveTimeout”属性。

<system.serviceModel>
    <bindings>
      <wsHttpBinding>
        <binding name="someBinding" receiveTimeout ="00:10:00">
          ...       
        </binding>
    </bindings>
  </system.serviceModel>

另请参阅绑定类的“closeTimeout”、“sendTimeout”和“openTimeout”属性。

您可以尝试在命令行界面中键入“netstat”以查看正在使用的端口。

我在一篇评论的基础上找到了解决办法 https://support.microsoft.com/en-us/help/896861/you-receive-error-401-1-when-you-browse-a-web-site-that-uses-integrate .

所以,我所做的只是将WCF链接从localhost改为计算机名,它就成功了!!
