C#的委托简单使用

namespace WindowsFormsApp1
{public delegate void setdetetest();//定义一个委托public partial class Form1 : Form{setdetetest detetest1;public Form1(){InitializeComponent();detetest1 = new setdetetest(run1);//委托实例化}private void run1(){textBox1.Text = "123456789";}private void button1_Click(object sender, EventArgs e){Thread th1 = new Thread(th1test);//开启一个线程。调用委托th1.Start();//开启线程}private void th1test(){this.Invoke(detetest1);//调用委托}}
}
