用Remoting激活远程对象时出现“类型的权限被拒绝”的异常，是什么回事？

Question

未处理的"System.Runtime.Remoting.RemotingException"类型的异常出现在mscorlib.dll中。
其他信息：激活RemoteHello.RemoteObject,RemoteHello,Version=1.0.2181.16110,Culture=neutral,PublicKeyToken=null类型的权限被拒绝。客户端：
RemotingConfiguration.RegisterActivatedClientType(typeof(RemoteObject),
                           "http://localhost:6791/HelloServer");
RemoteObject obj = new RemoteObject();请教。

Answer 1

public class RemoteObject : MarshalByRefObject
按引用编组的哦.

Answer 2

服务器端:
<configuration>
    <System.Runtime.Remoting>
        <application name="HelloServer">
            <service>
    <activated type="HelloServer.RemoteObject,RemoteObject"/>
            </service>
            <channels>
                <channel type="System.Runtime.Remoting.Channels.Tcp.TcpChannel,
                System.Runtime.Remoting" port="6791"/>
            </channels>
        </application>
    </System.Runtime.Remoting>
</configuration>客户:
<configuration>
    <system.runtime.remoting>
<application name="HelloClient">
    <client url="http://localhost:6791/HelloServer">
        <activated type="HelloServer.RemoteObject,RemoteObject"/>
    </client>
    <channels>
    <channel type="System.Runtime.Remoting.Channels.Tcp.TcpChannel,
    System.Runtime.Remoting" port="777"/>
    </channels>
</application>
    </system.runtime.remoting>
</configuration>
