使用wsDualHttpBinding在WCF中获取客户端IP地址

public string GetClientIPAddress()
{
    OperationContext context = OperationContext.Current;
    MessageProperties messageProperties = context.IncomingMessageProperties;
    RemoteEndpointMessageProperty endpointProperty = messageProperties[RemoteEndpointMessageProperty.Name] as RemoteEndpointMessageProperty;
    
    string clientIPAddress = endpointProperty.Address;
    return clientIPAddress;
}

<system.serviceModel>
  <bindings>
    <wsDualHttpBinding>
      <binding name="DualHttpBindingConfig" />
    </wsDualHttpBinding>
  </bindings>
  <services>
    <service name="YourServiceNamespace.YourServiceClass">
      <endpoint address="" binding="wsDualHttpBinding" bindingConfiguration="DualHttpBindingConfig" contract="YourServiceNamespace.IYourServiceContract" />
      <endpoint address="mex" binding="mexHttpBinding" contract="IMetadataExchange" />
    </service>
  </services>
</system.serviceModel>

YourServiceClient client = new YourServiceClient();
string clientIPAddress = client.GetClientIPAddress();
