1、多线程之跨线程操作控件NET 原则上禁止跨线程访问控件，因为这样可能造成错误的发生，推荐的解决方法是采用代理,用代理方法来间接操作不是同一线程创建的控件。第二种方法是禁止编译器对跨线程访问作检查，可以实现访问，但是出不出错不敢保证Control.CheckForIllegalCrossThreadCalls=false;最近我在做一个项目,遇到了跨线程要去访问页面控件.但是总是提示出错,不能在其它线程中修改创建控件的线程的控件的值,后来采用了匿名代理,结果很轻松地解决了.解决过程如下:首先在窗体上,创建一个listbox 与 lable.using System;using System.Co

22、发现它是一个static 的，也就是说无论我们在项目的什么地方修改了这个值，他就会在全局起作用。而且像这种跨线程访问是否存在异常，我们通常都会去检查。如果项目中其他人修改了这个属性，那么我们的方案就失败了，我们要采取另外的方案。下面来看第二种方案，就是使用delegate 和 invoke 来从其他线程中控制控件信息。网上有很多人写了这种控制方式，然而我看了很多这种帖子，表明上看来是没有什么问题的，但是实际上并没有解决这个问题，首先来看网络上的那种不完善的方式：public partial class Form1:Form private delegate void FlushClient()

24、hreadFuntion()while(true)this.textBox1.Text=DateTime.Now.ToString();Thread.Sleep(1000);使用这种方式我们可以看到跨线程访问的异常没有了。但是新问题出现了，界面没有响应了。为什么会出现这个问题，我们只是让新开的线程无限循环刷新，理论上应该不会文档编码:CW5D7U8H5O8 HR9L9L2J5H1 ZF9L2P4Q8C7文档编码:CW5D7U8H5O8 HR9L9L2J5H1 ZF9L2P4Q8C7文档编码:CW5D7U8H5O8 HR9L9L2J5H1 ZF9L2P4Q8C7文档编码:CW5D7U8H5O8

31、方式其实相当于把这个新开的线程“注入”到了主控制线程中，它取得了主线程的控制。只要这个线程不返回，那么主线程将永远都无法响应。就算新开的线程中不使用无限循环，使可以返回了。这种方式的使用多线程也失去了它本来的意义。现在来让我们看看推荐的解决方案(建议用该方案）：public partial class Form1:Form private delegate void FlushClient();/代理public Form1()InitializeComponent();private void Form1_Load(object sender,EventArgs e)Thread threa

40、elegate 的异步调用，大家可以看看：public partial class Form1:Form private delegate void FlushClient();/代理public Form1()InitializeComponent();private void Form1_Load(object sender,EventArgs e)Thread thread=new Thread(CrossThreadFlush);thread.IsBackground=true;thread.Start();private void CrossThreadFlush()FlushCli

41、ent=new FlushClient(ThreadFunction);FlushClient.BeginInvoke(null,null);private void ThreadFunction()while(true)this.textBox1.Text=DateTime.Now.ToString();Thread.Sleep(1000);这种方法也可以直接简化为(因为 delegate的异步就是开了一个异步线程):public partial class Form1:Form private delegate void FlushClient();/代理public Form1()Ini
