利用 MarshalByRefObject,在新的AppDomain里 创建线程安全对象.

1. ActionProxy

 

public class ActionProxy : MarshalByRefObject, IDisposable { private Action action = null; public void Run() { this.action(); } // Methods public ActionProxy(Type type, string action) { Object obj = Activator.CreateInstance(type); this.action = (Action)Delegate.CreateDelegate(typeof(Action), obj, action); } #region IDisposable Members public void Dispose() { action = null; } #endregion }

 

2.Program

 

public class Program{ public void Test() { AppDomain newAppDomain = null; ActionProxy action = null; try { newAppDomain = CreateNewAppDomain(Guid.NewGuid().ToString()); action = CreateActionProxy(newAppDomain, Test_001); action.Run(); } finally { if (action != null) { action.Dispose(); } if (newAppDomain != null) { AppDomain.Unload(newAppDomain); } } } public void Test_001() { Debug.WriteLine(AppDomain.CurrentDomain.FriendlyName); } public static AppDomain CreateNewAppDomain(string friendlyName) { AppDomainSetup setup = new AppDomainSetup(); setup.ApplicationBase = AppDomain.CurrentDomain.BaseDirectory; setup.ConfigurationFile = AppDomain.CurrentDomain.SetupInformation.ConfigurationFile; Evidence adevidence = AppDomain.CurrentDomain.Evidence; AppDomain newAppDomain = AppDomain.CreateDomain(friendlyName, adevidence, setup); return newAppDomain; } public static ActionProxy CreateActionProxy(AppDomain appDomain, Action action) { object[] actionProxyArgs = new object[] { action.Target.GetType(), action.Method.Name }; ActionProxy actionProxy = (ActionProxy)appDomain.CreateInstanceAndUnwrap( typeof(ActionProxy).Assembly.FullName, typeof(ActionProxy).FullName, false, BindingFlags.Default, null, actionProxyArgs, null, null, null); return actionProxy; }}
