通信对象System.ServiceModel.Channels.ServiceChannel不能用于通信，因为它处于Faulted状态

Question

try
{
    String endPointAddr = "net.tcp://localhost:8000/MyService";
    NetTcpBinding tcpBinding = new NetTcpBinding();
    tcpBinding.TransactionFlow = false;
    tcpBinding.Security.Transport.ProtectionLevel = System.Net.Security.ProtectionLevel.EncryptAndSign;
    tcpBinding.Security.Transport.ClientCredentialType = TcpClientCredentialType.Windows;
    tcpBinding.Security.Mode = SecurityMode.None;

    EndpointAddress endpointAddress = new EndpointAddress(endPointAddr);

    Console.WriteLine("::::: WCF Service Demo :::::");
    Console.WriteLine("Attempt to connect to: " + endPointAddr);


    ChannelFactory<IServices> WCF = new ChannelFactory<IServices>(tcpBinding, endpointAddress);
    IServices proxy = WCF.CreateChannel();

    using (WCF as IDisposable)
    {
        Console.WriteLine("Connected to: " + endPointAddr);
        Dictionary<long, DATALINK> dicDataLink = proxy.getDataLink();
        lblCTRGData.Text = dicTRGDataLink.Count.ToString();
    }
}
catch (Exception ex)
{
    lblCTRGData.Text = ex.Message.ToString();
}
Console.ReadLine();

如果字典有50到100条记录但是记录大于发生的错误，则此代码会流畅地运行通信对象System.ServiceModel.Channels.ServiceChannel不能用于通信，因为它处于故障状态

Answer 1

没有看到堆栈跟踪或失败的代码，但听起来你的wcf客户端由于某种原因而失败，因为某些原因导致它进入故障状态并且你试图再次使用它。或者您正在使用代理的using语句。
