C# 使用主线程更新winform界面

工程中很多地方用异步线程处理 返回在界面显示,如果界面更新比较少的话,可以单个封装Delegate用Invoke调用,

如果地方过多.就需要 UI主线程轮训,以及 lazy Update了(就是如果在同一帧里面,如果多次调用UpdateXXX,只更新一次)

解决 UI跨线程更新的问题

直接上代码了:

public partial class Form1 : Form
    {
        public delegate void mainThreadTickDelegate();
 	private static Form1 _ins; 
        public Form1()
        {
            InitializeComponent();
            _ins = this;
        }
 	private void Form1_Load(object sender, EventArgs e)
        {
 		Task _t = new Task(_mainThreadTick);
            	_t.Start();
        }

        public mainThreadTickDelegate Event_MainThreadTick;
	void _mainThreadTick()
        {
            //log("_mainThreadTick");
            while (true)
            {
                updateClientServicesViewdelegate d = new updateClientServicesViewdelegate(_ins._mainThreadTickInstance);
                _ins.Invoke(d);
                Thread.Sleep(1000);
            }
        }
        void _mainThreadTickInstance()
        {
            //log("_mainThreadTickInstance");
            if (Event_MainThreadTick != null)
            {
                Event_MainThreadTick();
            }
            _updateClientServicesView();
        }
  	bool _needUpdateClientServicesView = true;
       
        void _updateClientServicesView()
        {
            if (!_needUpdateClientServicesView)
            {
                return;
            }
            _needUpdateClientServicesView = false;
	//后续更新逻辑
	}
}
