尝试添加dataContractSerializer服务行为：

 <   servicebehaviors  >  
<  行为 >  
<   datacontractserializer     maxitemsinobjectgraph   =  2147483647    /  >

Wow, I have been banging my head against the wall for about 5+ days now. I have a WCF Service Application (Windows Services hosted), using net.tcp binding with Windows Authentication, running on a remote server. I created a test Windows client, added a service reference to my IDataService, then created a ChannelFactory for my proxy. When calling the service I receive an error "The socket connection was aborted..."


Any suggestions on what I have done wrong here?


Here is my Win code call (this is only test code):

// These setting are exactly as the web.config in the IDataService.
NetTcpBinding binding = new NetTcpBinding() ;
binding.TransactionFlow = false;
binding.PortSharingEnabled = true;
binding.Security.Transport.ProtectionLevel = System.Net.Security.ProtectionLevel.EncryptAndSign;
binding.Security.Transport.ClientCredentialType = TcpClientCredentialType.Windows;
binding.Security.Mode = SecurityMode.None;
binding.ReceiveTimeout = TimeSpan.MaxValue;
        
var endPointAddress = new EndpointAddress(new Uri("net.tcp://SOMESERVER:9000/OperationsDataService.DataService.svc"), new SpnEndpointIdentity("MYSERVICE/MyMachine"));

var proxy = ChannelFactory<idataservice>.CreateChannel(binding, endPointAddress);

// SpParameter is a [DataContract] class in the WCF interface service that has a few [DataMembers].
SpParameter[] spParams = new SpParameter[1];
spParams[0] = new SpParameter();
spParams[0].Paraname = @"@Commodity";
spParams[0].Paratype = @"char(1)";
spParams[0].Paravalue = @"''P''";

// The proxy method returns a [DataContract] called ReturnResults which is basically a DataSet.  This DataSet gets added into the grid cntrol.
dataGridViewReturn.DataSource = proxy.ExecuteStoredProcedure("PowerTrading_Dev_I", "", spParams, true);

My web.config:

You are most likely getting a size limit on your data.

Try adding the dataContractSerializer service behaviour:

<servicebehaviors>
 <behavior>
          <datacontractserializer maxitemsinobjectgraph="2147483647" />
          ....
        </behavior>
...
</servicebehaviors>
