我将 NetTcpBinding 与 Streamed TransferMode 一起使用。现在我尝试将回调实现为双工,但收到错误消息。可以将 NetTcpBinding 与 Streamed TransferMode 一起使用并使用(双工)回调服务合同吗?背景: - 我使用 NetTcpBinding 因为它速度快而且没有 nat 问题 - 我使用流模式,因为我也传输大文件。

配置:

 <netTcpBinding>
    <binding name="DuplexBinding" transferMode="Streamed"
                closeTimeout="00:10:00"  openTimeout="00:10:00" receiveTimeout="00:10:00" sendTimeout="00:10:00"  transactionFlow="false" hostNameComparisonMode="StrongWildcard" maxBufferPoolSize="104857600" maxReceivedMessageSize="104857600"
             >
      <readerQuotas maxDepth="104857600" maxStringContentLength="104857600" maxArrayLength="104857600" maxBytesPerRead="104857600" maxNameTableCharCount="104857600"/>
      <reliableSession enabled="true" ordered="true" inactivityTimeout="00:10:00"/>
      <security mode="None" />
    </binding>
  </netTcpBinding>

合同:

IMyDataService.cs

   [ServiceContract(CallbackContract = typeof(INotifyCallback))]
    public interface IMyDataService
    {
        [OperationContract(ProtectionLevel = System.Net.Security.ProtectionLevel.None)]
        [FaultContract(typeof(MyFaultException))]
        [FaultContract(typeof(MyUserAlreadyLoggedInFaultException))]
        [FaultContract(typeof(AuthorizationFaultException))]
        Guid Authenticate(Guid clientID, string userName, string password, bool forceLogin);
    }


INotifyCallback.cs

    public interface INotifyCallback
    {
        [OperationContract(IsOneWay = true)]
        void ShowMessageBox(string message);
    }

设置 transferMode="Streamed" 时出现错误

合同需要双工,但绑定“NetTcpBinding”不支持它或未正确配置以支持它。

每个人都可以建议谢谢

在您的客户端代码中,确保您使用DuplexChannelFactory创建到服务器的通道:

INotifyCallback callbackObject = new NotifyCallbackImpl(); //your concrete callback class
var channelFactory = new DuplexChannelFactory<IMyDataServce>(callbackObject); //pick your favourite constructor!
IMyDataService channel = channelFactory.CreateChannel();
try {
    var guid = channel.Authenticate(....);
    //... use guid...
} finally {
    try {
        channel.Close();
    } catch (Exception) {
        channel.Abort();
    }
}
