Question

我的问题是标题中提到的错误。

我正在尝试将对象用作CAO类型。我已经装好了装配，服务员和客户。

当我尝试使用该行时发生：

JamesBondCar[] cars = { new JamesBondCar("one", 100, true, true), 
                                      new JamesBondCar("Two", 100, true, true), 
                                      new JamesBondCar("Three", 100, true, true) };
CarProvider cp=new CarProvider(cars);

当我使用默认构造函数时，这是有效的。可能是什么问题？

编辑：这是CarProvider的代码：

 public class CarProvider : MarshalByRefObject 
    {
        private ArrayList theJBCars = new ArrayList(); 
        public CarProvider()
        {
            Console.WriteLine("Utworzono CarProvider.");
            theJBCars.Add(new JamesBondCar("QMobile", 140, true, true));
            theJBCars.Add(new JamesBondCar("FLyer", 140, true, false));
            theJBCars.Add(new JamesBondCar("Swimmer", 140, false, true));
            theJBCars.Add(new JamesBondCar("BasicJBC", 140, false, false));
        }
        public CarProvider(JamesBondCar[] theCars)
        { 
            Console.WriteLine("Utworzono JamesBondCar za pomocą niestandardowego konstruktora.");
            theJBCars.AddRange(theCars);
        }
        public ArrayList GetAllAutos() 
        { return theJBCars; }
        public JamesBondCar GetJBCByIndex(int i)
        { return (JamesBondCar)theJBCars[i]; }
    }

服务员的App.config：

<configuration>
  <system.runtime.remoting>
    <application>
      <service>
        <activated
            type="CarGeneralAsm.CarProvider,CarGeneralAsm"/>
      </service>
        <channels>
          <channel ref="http" port="32469"/>
        </channels>
    </application>
  </system.runtime.remoting>
</configuration>

客户端的App.config：

<configuration>
  <system.runtime.remoting>
    <application name="TestowanieTypówCAO">
      <client
        url="http://localhost:32469">
        <activated
          type="CarGeneralAsm.CarProvider,CarGeneralAsm"/>
      </client>
      <channels>
        <channel ref="http"/>
      </channels>
    </application>
  </system.runtime.remoting>
</configuration>

我想我终于明白了。 @Greg Burghardt建议的帖子让我在MSDN中阅读了更多关于它的内容，我发现它与.NET 4.0中有关安全性的更改有关。

并且“typeFilterLevel = full”是解决方案，但我的服务器/客户端* .config文件中还有其他错误。下面，我介绍他们的正确版本：

<强>客户端

<configuration>
  <system.runtime.remoting>
    <application name="TestowanieTypówCAO">
      <channels>
        <channel ref="http">
          <clientProviders>
            <formatter ref="soap"/>
          </clientProviders>
          <serverProviders>
            <formatter ref="soap"  typeFilterLevel="Full"/>
          </serverProviders>
        </channel>
      </channels>
      <client url="http://localhost:32469">
        <activated type="CarGeneralAsm.CarProvider,CarGeneralAsm"/>
      </client>    
    </application>
  </system.runtime.remoting>
</configuration>

<强> Serwer

<configuration>
  <system.runtime.remoting>
    <application>
      <channels>
          <channel ref="http" port="32469">
             <serverProviders>
                <formatter ref="soap" typeFilterLevel="Full"/>
             </serverProviders>
             <clientProviders>
               <formatter ref="soap"/>
             </clientProviders>
            </channel>
        </channels>
      <service>
        <activated
            type="CarGeneralAsm.CarProvider,CarGeneralAsm"/>
      </service>    
    </application>
  </system.runtime.remoting>
</configuration>

我知道.NET Remoting现在并不常用，因为WCF，但我只是想知道它是如何工作的，然后才进入WCF。

干杯！
