C# 防止Winform窗体假死

1.在处理较慢的代码前面加DoEvents()
Application.DoEvents();

2.使用多线程

Thread th = Thread.CurrentThread;
            th.Name = "MainThread";
            Console.WriteLine("This is {0}", th.Name);
          Console.ReadKey();

3.使用委托异步，对于有参的，

    //调用
    Application.DoEvents();
     lock (SequenceLock)
      {
    Run_delegate_zi run = new Run_delegate_zi(Run_zi);                
   IAsyncResult result = run.BeginInvoke(tbname,  i, null, null);
   //有返回值可去掉下面代码
    //string result1 = run.EndInvoke(result);
   }
//顶一个Lock
private static readonly object SequenceLock = new object();
//定义委托及方法名称
 private delegate void  Run_delegate_zi( string tbname, int i);
   public void Run_zi(string tbname, int i)//无返回值
   {
  //...业务代码
   }


//4.解决线程间操作无效
 //在窗体Load方法里写
 System.Windows.Forms.Control.CheckForIllegalCrossThreadCalls = false;
