本文介绍了一个使用 C# 实现的简单多线程应用程序案例。该应用通过一个独立线程不断向 ListBox 控件中添加字符串，演示了如何启动和终止线程。此外，还展示了如何禁用跨线程调用检查。

        public Form1()
        {
            Form.CheckForIllegalCrossThreadCalls = false;
            InitializeComponent();
            Sample st = new Sample(listBox1);
        t = new Thread(new ThreadStart(st.work));
        }
        public class Sample
        {
            private ListBox listBox1;

            public Sample(ListBox a)
            {
                this.listBox1 = a;
            }

            public void work()
            {
                while (true)
                {

                    listBox1.Items.Add("Sample的work线程在运行");
                }
            }
        }

        private void button1_Click(object sender, EventArgs e)
        {
            t.Start();
        }

        private void button2_Click(object sender, EventArgs e)
        {
            if (t.IsAlive)
            {
                t.Abort();
            }
        }
    }

}
