c#中使用InvokeRequired安全处理跨线程操作的方法与实例详解

using System;
using System.Windows.Forms;

public class MyForm : Form
{
    private Button myButton;

    public MyForm()
    {
        myButton = new Button();
        myButton.Text = "Click me";
        myButton.Location = new System.Drawing.Point(10, 10);
        myButton.Click += new EventHandler(MyButton_Click);
        this.Controls.Add(myButton);
    }

    private void MyButton_Click(object sender, EventArgs e)
    {
        if (myButton.InvokeRequired)
        {
            // 如果当前线程不是UI线程，则使用Invoke方法将操作委托给UI线程
            myButton.Invoke((MethodInvoker)delegate
            {
                MyButton_Click(sender, e);
            });
        }
        else
        {
            // 如果当前线程是UI线程，则直接执行操作
            MessageBox.Show("Button clicked!");
        }
    }

    [STAThread]
    static void Main()
    {
        Application.EnableVisualStyles();
        Application.SetCompatibleTextRenderingDefault(false);
        Application.Run(new MyForm());
    }
}
