为什么子域关闭程序异常？
为什么一个应用程序域中的异常会影响另一个应用程序域？
如何防止程序关闭？
using System;
using System.Reflection;
using System.Threading;
namespace domain
{
public class Worker : MarshalByRefObject
{
public static void NotMyCodeThreadProc()
{
throw new Exception();
}
public void NotMyCode()
{
var thread = new Thread(NotMyCodeThreadProc);
thread.Start();
thread.Join();
}
}
class Program
{
static void Main()
{
AppDomain ad = AppDomain.CreateDomain("New domain");
Worker remoteWorker = (Worker) ad.CreateInstanceAndUnwrap(Assembly.GetExecutingAssembly().FullName, "domain.Worker");
try
{
remoteWorker.NotMyCode();
}
catch
{
}
Console.WriteLine("!");
Console.ReadLine();
}
}
}
Why exception in one application domain affect another application domain?
How do I prevent the closing of the program?
using System;
using System.Reflection;
using System.Threading;
namespace domain
{
public class Worker : MarshalByRefObject
{
public static void NotMyCodeThreadProc()
{
throw new Exception();
}
public void NotMyCode()
{
var thread = new Thread(NotMyCodeThreadProc);
thread.Start();
thread.Join();
}
}
class Program
{
static void Main()
{
AppDomain ad = AppDomain.CreateDomain("New domain");
Worker remoteWorker = (Worker) ad.CreateInstanceAndUnwrap(Assembly.GetExecutingAssembly().FullName, "domain.Worker");
try
{
remoteWorker.NotMyCode();
}
catch
{
}
Console.WriteLine("!");
Console.ReadLine();
}
}
}

在 .NET 2.0（及更高版本）中，线程中未处理的异常会导致整个进程终止。
您可以按照 Hans 的建议更改该策略，或者您可以简单地用 try/catch 包装代码并处理异常。
In .NET 2.0 (and above), an unhandled exception in a thread causes the entire process to terminate.
You can change that policy by following Hans' advice, or you can simply wrap your code with try/catch and handle the exception.
