示例

下面的代码示例演示如何使用 ILogicalThreadAffinative 接口将 主体和标识对象 传输到远程位置进行标识。 若要查看示例中使用的类的代码 HelloServiceClass ，请参阅 方法的示例 GetData 。 若要查看此示例中使用的服务器类的代码，请参阅 类的示例 RegisterActivatedServiceType 。 若要查看示例中使用的客户端类的代码，请参阅 类的示例 CallContext 。

[Serializable]
public ref class LogicalCallContextData: public ILogicalThreadAffinative

public:

   property String^ numOfAccesses 
   {
      String^ get()
      {
         return String::Format( "The identity of {0} has been accessed {1} times.", _principal->Identity->Name, _nAccesses );
      }
   }

      IPrincipal^ get()

         _nAccesses++;

   }

   LogicalCallContextData( IPrincipal^ p )

      _nAccesses = 0;
      _principal = p;
   }
}

<Serializable()> Public Class LogicalCallContextData
   Implements ILogicalThreadAffinative

   Private _nAccesses As Integer
   Private _principal As IPrincipal
   
   
   Public ReadOnly Property numOfAccesses() As String
      Get
         Return [String].Format("The identity of {0} has been accessed {1} times.", _principal.Identity.Name, _nAccesses)
      End Get
   End Property
   
   
   Public ReadOnly Property Principal() As IPrincipal
      Get
         _nAccesses += 1
         Return _principal
      End Get
   End Property
   
   
   Public Sub New(p As IPrincipal)
      _nAccesses = 0
      _principal = p
   End Sub

End Class

注解

当对另 AppDomain一个 中的 对象进行远程方法调用时，当前 CallContext 类将生成一个 LogicalCallContext ，该调用与对远程位置的调用一起传输。 只有公开 ILogicalThreadAffinative 接口并存储在 中的 CallContext 对象才会在 外部 AppDomain传播。 不支持此接口的对象不会在具有远程方法调用的实例中 LogicalCallContext 传输。
