:) 我有一个奇怪的问题。 我有一个自托管WCF服务，从数据库获取数据并发送到WPF客户端。读取大数据块时超时（但不是超时），但只有外部VS2010
现在，我遇到了“假超时问题”（“套接字连接重置，这可能是由处理消息的错误导致的，”......等），我解决了它纠正安全标签（它是“无“，我纠正为”运输“
当我执行VS2010环境（比如说，没有调试和WcfSvcHost，但有服务在MMC中运行并从Windows资源管理器执行该程序），我又去了相同的错误，这次只在从数据库读取大量数据时（比如25k行表）
这里是服务器App.config：

...这是代码片段，我创建的ChannelFactory，和消费服务
ChannelFactory<IWCFSrvLib> cf = new ChannelFactory<IWCFSrvLib>(new NetTcpBinding());
((NetTcpBinding)cf.Endpoint.Binding).CloseTimeout = new TimeSpan(0, 5, 0);
((NetTcpBinding)cf.Endpoint.Binding).OpenTimeout = new TimeSpan(0, 5, 0);
((NetTcpBinding)cf.Endpoint.Binding).ReceiveTimeout = new TimeSpan(0, 5, 0);
((NetTcpBinding)cf.Endpoint.Binding).SendTimeout = new TimeSpan(0, 5, 0);
((NetTcpBinding)cf.Endpoint.Binding).TransactionFlow = false;
((NetTcpBinding)cf.Endpoint.Binding).TransferMode = TransferMode.Buffered;
((NetTcpBinding)cf.Endpoint.Binding).TransactionProtocol = TransactionProtocol.OleTransactions;
((NetTcpBinding)cf.Endpoint.Binding).MaxReceivedMessageSize = Int32.MaxValue;
((NetTcpBinding)cf.Endpoint.Binding).MaxConnections = 10;
((NetTcpBinding)cf.Endpoint.Binding).MaxBufferPoolSize = Int32.MaxValue;
((NetTcpBinding)cf.Endpoint.Binding).MaxBufferSize = Int32.MaxValue;
((NetTcpBinding)cf.Endpoint.Binding).Security.Mode = SecurityMode.Transport;
((NetTcpBinding)cf.Endpoint.Binding).Security.Message.ClientCredentialType = MessageCredentialType.Windows;
((NetTcpBinding)cf.Endpoint.Binding).ReaderQuotas.MaxArrayLength = Int32.MaxValue;
((NetTcpBinding)cf.Endpoint.Binding).ReaderQuotas.MaxBytesPerRead = Int32.MaxValue;
((NetTcpBinding)cf.Endpoint.Binding).ReaderQuotas.MaxDepth = 32;
((NetTcpBinding)cf.Endpoint.Binding).ReaderQuotas.MaxNameTableCharCount = Int32.MaxValue;
((NetTcpBinding)cf.Endpoint.Binding).ReaderQuotas.MaxStringContentLength = Int32.MaxValue;
((NetTcpBinding)cf.Endpoint.Binding).ReliableSession.Enabled = false;
((NetTcpBinding)cf.Endpoint.Binding).ReliableSession.InactivityTimeout = new TimeSpan(0, 10, 0); ;
((NetTcpBinding)cf.Endpoint.Binding).ReliableSession.Ordered = true;
foreach (OperationDescription op in cf.Endpoint.Contract.Operations)
{
DataContractSerializerOperationBehavior dataContractBehavior =
op.Behaviors[typeof(DataContractSerializerOperationBehavior)]
as DataContractSerializerOperationBehavior;
if (dataContractBehavior != null)
{
dataContractBehavior.MaxItemsInObjectGraph = int.MaxValue;
}
}
Globs.catClient = cf.CreateChannel(new EndpointAddress("net.tcp://localhost:8732/WCFSrvLib"));
if (Globs.catClient == null)
throw new Exception("Unable to initialize server");
try
{
Globs.CatData = new List<CATData>(Globs.catClient.getData(out err, Globs.connsrv));
Globs.HandleError(err);
UpdateProgressBar();
}
catch (Exception e)
{
if (!NotifyError("Data", e.Message))
return false;
}
有一对夫妇的是内部功能，所以不在这里定义，但他们不是问题的关键。 请注意，在尝试查找此问题的解决方案时，已经放置了channelfactory中的所有设置。
如果您需要更详细或代码，只是要求提前:)
