异常抛出

• 异常抛出要在线程代码中抛出，否则捕获不到

using System;

using System.Threading;

namespace testthread_keyword_lock

{

    class Program

    {

        static void Main(string[] args)

        {

             //异常可以捕获

            var t = new Thread(faultyThread);

            t.Start();

            t.Join();

            //异常不能捕获

            try

            {

                t = new Thread(badfaultyThread);

                t.Start();

            }

            catch (Exception ex)

            {

                Console.WriteLine("we won't get here");

            }

        }

        static void badfaultyThread()

        {

            Console.WriteLine("starting a bad faulty thread ....");

            Thread.Sleep(1000);

            throw new Exception("BOOM");

        }

        static void faultyThread()

        {

            try

            {

                Console.WriteLine("starting a faulty thread.........");

                Thread.Sleep(1000);

                throw new Exception("BOOM");

            }

            catch (Exception ex)

            {

                Console.WriteLine("Exception handled：{0}",ex.Message);

            }

        }

    }

}

• 可以在app.config中使用错误策略

<configuration>

   <runtime>

       <legacyUnhandledExceptionPolicy enable="1"/>

   </runtime>

</configuration>
