几种多线程参数传递方法

[1]通过构造函数传递

using System;using System.Threading;using System.Runtime.Remoting.Messaging;namespace PCTools{ class Test { static void Main(string[] args) { Console.WriteLine("========Test Begin========="); //Create B b = new B("[1]构造函数传递法!"); //Start new Thread(b.Func).Start(); Console.WriteLine("===========Test End========="); Console.ReadKey(); } } class B { private string s; public B(string s) { this.s = s; } public void Func() { Console.WriteLine(s); } }}

 

[2]线程池传递参数法

using System;using System.Threading;using System.Runtime.Remoting.Messaging;namespace PCTools{ class Test { static void Main(string[] args) { Console.WriteLine("========Test Begin========="); //Create B b = new B(); //Start ThreadPool.QueueUserWorkItem(new WaitCallback(b.Func), "[2]线程池传递参数法"); Console.WriteLine("===========Test End========="); Console.ReadKey(); } } class B { public void Func(string s) { Console.WriteLine(s); } public void Func(object s) { this.Func((string)s); } }}

 

[3]回调法,并且能够处理返回值

//注意:CallBack必须是static的

using System;using System.Threading;using System.Runtime.Remoting.Messaging;namespace PCTools{ //delegate class Test { delegate string MyMethodDelegate(string s); static void Main(string[] args) { Console.WriteLine("========Test Begin========="); //Create B b = new B(); //Start MyMethodDelegate MyMethod = b.Func; MyMethod.BeginInvoke("[3]回调法,并且能够处理返回值", CallBack, null); Console.WriteLine("===========Test End========="); Console.ReadKey(); } static public void CallBack(IAsyncResult result) { AsyncResult async = (AsyncResult)result; MyMethodDelegate DelegateInstance = (MyMethodDelegate)async.AsyncDelegate; Console.WriteLine(DelegateInstance.EndInvoke(result)); } } class B { public string Func(string s) { return s; } }}

 

[4]回调法,并且能够处理返回值","+多参数版"

using System;using System.Threading;using System.Runtime.Remoting.Messaging;namespace PCTools{ //delegate class Test { delegate string MyMethodDelegate(string s ,string t); static void Main(string[] args) { Console.WriteLine("========Test Begin========="); //Create B b = new B(); //Start MyMethodDelegate MyMethod = b.Func; MyMethod.BeginInvoke("[5]回调法,并且能够处理返回值","+多参数版", CallBack, null); //方法五 Thread fThread = new Thread(b.Func); fThread.Start("[4]处理单个参数"); Console.WriteLine("===========Test End========="); Console.ReadKey(); } static public void CallBack(IAsyncResult result) { AsyncResult async = (AsyncResult)result; MyMethodDelegate DelegateInstance = (MyMethodDelegate)async.AsyncDelegate; Console.WriteLine(DelegateInstance.EndInvoke(result)); } } class B { public string Func(string s, string t) { return s + t; } public void Func(string s) { Console.WriteLine(s); } public void Func(object s) { this.Func((string)s); } }}

 

[5]最后来个简单点的

using System.Threading;namespace ConsoleApplication2{ class Program { static void Main(string[] args) { Thread fThread = new Thread(new ParameterizedThreadStart(B.Func)); fThread.Start(2); } } class B { public static void Func(object a) { int i = (int)a; Console.WriteLine("Smile"); } }}
