C# 同一应用程序域不同线程之间的参数传递方式_.NET_编程开发_程序员俱乐部

很久没有写博客了，最近的项目不用写代码。今天没事就看看thread之间的参数传递方式，这里主要适用于运行在不同线程的两个方法之间参数传递。直接看代码

1。方法之间直接传递参数

   void DemoParam()
        {
            Console.WriteLine("DemoParam:" + Thread.CurrentThread.ManagedThreadId);
            //Thread t = new Thread(new ParameterizedThreadStart(testparam));
            //t.Start("majaing");
            ThreadPool.QueueUserWorkItem(new WaitCallback(testparam),"majaing");
        }
        void testparam(object obj)
        {
            Console.WriteLine("DemoParam:" + Thread.CurrentThread.ManagedThreadId);        
            Console.WriteLine(obj.ToString());
        }

2。借助Static

 //[ThreadStatic]
        static string namekey;
        void DemoStatic()
        {
            Console.WriteLine("Static:" + Thread.CurrentThread.ManagedThreadId);
            namekey = "majiang";
            ThreadPool.QueueUserWorkItem(new WaitCallback(testStatic));
        }
        void testStatic(object obj)
        {
            Console.WriteLine("Static:" + Thread.CurrentThread.ManagedThreadId);

            Console.WriteLine(namekey);
        }

3。借助AppDomain

 void DemoAppDomain()
        {
            Console.WriteLine("AppDomain:"+Thread.CurrentThread.ManagedThreadId);
            AppDomain.CurrentDomain.SetData("name", "majiang");
            ThreadPool.QueueUserWorkItem(new WaitCallback(testAppDomain));
        }
        void testAppDomain(object obj)
        {
            Console.WriteLine("AppDomain:"+Thread.CurrentThread.ManagedThreadId);
            var a = AppDomain.CurrentDomain.GetData("name");
            Console.WriteLine(a);
        }

4。借助CallContext

  void DemoCallContext()
        {
            Console.WriteLine("CallContext"+Thread.CurrentThread.ManagedThreadId);
           // ExecutionContext.SuppressFlow();
            CallContext.LogicalSetData("name", "majiang");
            ThreadPool.QueueUserWorkItem(new WaitCallback(testCallContext));
           
        }
        void testCallContext(object obj)
        {
            Console.WriteLine("CallContext"+Thread.CurrentThread.ManagedThreadId);
            var a = CallContext.LogicalGetData("name");
            Console.WriteLine(a);
        }
