mscorlib.dll 中发生了 'System.Security.SecurityException' 类型的未处理异常
An unhandled exception of type 'System.Security.SecurityException' occurred in mscorlib.dll
我的问题是标题中提到的错误。
我正在尝试使用 objects 作为 CAO 类型。我已经完成了正确的装配、服务器和客户端。
当我尝试使用线路时发生：
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);
这在我使用默认构造函数时有效。
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]; }
}

我想我终于明白了。
@Greg Burghardt 的建议帖子让我在 MSDN 中阅读了更多相关信息，我发现它与 .NET 4.0 中有关安全性的更改有关。
"typeFilterLevel=full" 是解决方案，但我的 server/client *.config 文件中还有其他错误。下面，我展示他们的正确版本：

我知道 .NET Remoting 现在不常使用，这是 WCF 的原因，但我只是想在进入 WCF 之前了解它是如何工作的。
干杯！
