我使用NetTcpBinding和Streamed TransferMode。现在我试图以双工方式实现回调,但是我收到了错误消息。可以将NetTcpBinding与Streamed TransferMode一起使用并使用(双工)回调服务合同吗? 的背景: - 我使用NetTcpBinding,因为它很快,并且没有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 =&#34; Streamed&#34;
时出错合同要求双工,但绑定&#39; NetTcpBinding&#39;不支持 它或者没有正确配置以支持它。
每个人都可以建议谢谢

在您的客户端代码中,请确保您使用DuplexChannelFactory创建到服务器的频道:
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();
}
}
[编辑]自动生成的服务引用的代理应该扩展DuplexClientBase。
