为什么我仍然得到异常：

The formatter threw an exception while trying to deserialize the message: 
There was an error while trying to deserialize parameter http://tempuri.org/:GetData.
The InnerException message was 'Maximum number of items that can be serialized or deserialized in an object graph is '65536'. 
Change the object graph or increase the MaxItemsInObjectGraph quota. '.

似乎<dataContractSerializer maxItemsInObjectGraph="2147483647"/>在两个App.config文件中都忽略了。为什么？

在客户端，请参阅标记的 3 行****：

    <client>
        <endpoint address="http://.../Design_Time_Addresses/Service2/"
****        behaviorConfiguration="foo"
            binding="wsHttpBinding" bindingConfiguration="WSHttpBinding_IService2"
            contract="Service2Reference.IService2"
            name="WSHttpBinding_IService2">
            <identity>
                <dns value="localhost" />
            </identity>
        </endpoint>
        <endpoint address="net.tcp://.../Design_Time_Addresses/Service1/"
****        behaviorConfiguration="foo"
            binding="netTcpBinding" bindingConfiguration="NetTcpBinding_IService1"
            contract="Service1Reference.IService1" name="NetTcpBinding_IService1">
            <identity>
                <dns value="localhost" />
            </identity>
        </endpoint>
    </client>
  <behaviors>
    <endpointBehaviors>
****  <behavior name="foo">
        <dataContractSerializer maxItemsInObjectGraph="2147483647"/>
      </behavior>
    </endpointBehaviors>
  </behaviors>

添加到配置

<behaviors> 
    <endpointBehaviors> 
        <behavior name="Behaviors.EndpointBehavior"> 
            <dataContractSerializer maxItemsInObjectGraph="2147483647" /> 
        </behavior> 
    </endpointBehaviors> 
</behaviors

然后用行为定义你的客户

<client> 
    <endpoint address=http://localhost:9997/Services/MyService 
        behaviorConfiguration="Behaviors.EndpointBehavior" 
        binding="wsHttpBinding" bindingConfiguration="WSHTTPBinding.Configuration.Client" 
        contract="IAppointments" name="Client.EndpointConfiguration" /> 
</client>

或者在后面的代码中做

foreach ( var operation in channelFactory.Endpoint.Contract.Operations )   
{   
    var behavior = operation.Behaviors.Find() as DataContractSerializerOperationBehavior;   
    if ( behavior != null )   
    {   
        behavior.MaxItemsInObjectGraph = 2147483647;       
    }   
}

我认为您还必须装饰服务器端定义和客户端端点。

我通过在 C# 代码中添加行为解决了这个问题。

client.Endpoint.Behaviors.Remove(typeof(CallbackBehaviorAttribute));
client.Endpoint.Behaviors.Add(new CallbackBehaviorAttribute() { MaxItemsInObjectGraph = 2147483647 });

问题可能是由于使用带有 的ServiceClient构造函数引起的InstanceContext，Binding因此忽略EndpointAddress了 from 的行为。app.config
