Question

我在本地使用WCF服务来计算一些信息，这是C＃，并返回数据。我返回的数据是一个浮动列表List<List< float>>的列表，其中共有4个浮点数。每个浮动列表包含400个项目，每个集合中有180个这样的列表。那么List<List<float>>的4个

我最初没有足够的空间错误，然后将大小更新为最大2,000,000字节。

<?xml version="1.0" encoding="utf-8"?>
<configuration>
<system.serviceModel>
    <bindings>
        <netTcpBinding>
            <binding name="NetTcpBinding_IExternalBallistics" closeTimeout="01:10:00"
                openTimeout="01:10:00" receiveTimeout="01:10:00" sendTimeout="01:10:00"

                maxBufferPoolSize="2000000" maxBufferSize="2000000" maxConnections="10"
                maxReceivedMessageSize="2000000">

                    <message clientCredentialType="Windows" />
                </security>
            </binding>
        </netTcpBinding>
    </bindings>
    <client>
        <endpoint address="net.tcp://localhost:6100/ExternalBallistics"
            binding="netTcpBinding" bindingConfiguration="NetTcpBinding_IExternalBallistics"
            contract="IExternalBallistics" name="NetTcpBinding_IExternalBallistics" />
    </client>
</system.serviceModel>
</configuration>

我也在我的主机中手动设置了这些值。

private void InitializeServiceHost()
{
    if (_serviceHost != null)
    {
        _serviceHost.Close();
    }

    Uri address = new Uri("net.tcp://localhost:6100/ExternalBallistics");
    NetTcpBinding binding = new NetTcpBinding(SecurityMode.None);
    binding.MaxReceivedMessageSize = 2000000;
    binding.MaxBufferSize = 2000000;
    binding.MaxBufferPoolSize = 2000000;
    binding.CloseTimeout = new TimeSpan(1, 10, 0);
    binding.OpenTimeout = new TimeSpan(1, 10, 0);
    binding.ReceiveTimeout = new TimeSpan(1, 10, 0);
    binding.SendTimeout = new TimeSpan(1, 10, 0);
    _serviceHost = new ServiceHost(typeof(ExternalBallisticsImpl), address);
    _serviceHost.Description.Behaviors.Add(GetMetadataBehavior());
    _serviceHost.CloseTimeout = new TimeSpan(1, 10, 0);
    _serviceHost.OpenTimeout = new TimeSpan(1, 10, 0);
    _serviceHost.AddServiceEndpoint(typeof(IExternalBallistics), binding, address);
    _serviceHost.AddServiceEndpoint(ServiceMetadataBehavior.MexContractName, MetadataExchangeBindings.CreateMexTcpBinding(), "mex");

    _serviceHost.Open();
}

我还将超时设置为1小时10分钟。

我得到的错误是 The socket connection was aborted. This could be caused by an error processing your message or a receive timeout being exceeded by the remote host, or an underlying network resource issue. Local socket timeout was '01:09:59.9770000'.

现在超时发生在30秒内。我有一个单元测试我正在运行，服务正确地执行所有操作，并且回复包含有效数据，但是当它返回此回复时，我总是会收到此错误。

我一直在搜索，我无法得到任何解决方案，因为我看到的只是通知我增加缓冲区/超时时间。

虽然它被报告为超时例外，但可能是另一个问题。

您是否尝试Set set maxItemsInObjectGraph以确保您可以发送大对象图。

  <serviceBehaviors>

    <behavior name="MyBehavior">

      <dataContractSerializer maxItemsInObjectGraph="2147483647"/>

      <serviceMetadata />

    </behavior>

  </serviceBehaviors>

</behaviors>

Answer 2

正如@Tim在他的评论中所建议的那样，这可能是服务器在约30秒后无法与客户端通信的问题。客户可能已经关闭了它的连接。

确保客户端上的绑定设置与服务器的绑定设置相匹配。特别是，请确保客户端的receiveTimeout值类似于服务器的sendTimeout。

WCF服务失败，在30秒内超时1小时
