Winform开发遇到的问题之有无参线程和委托

对于线程与委托的知识也不是了解的很多，仅限稍微的使用而已。也是百度去参考教程而已

1.实体类：

    /// <summary>
    /// 实体类
    /// </summary>
    public class TestModue 
    {
        private int id;

        public int Id
        {
            get { return id; }
            set { id = value; }
        }

        private int old;

        public int Old
        {
            get { return old; }
            set { old = value; }
        }

        private string sex;

        public string Sex
        {
            get { return sex; }
            set { sex = value; }
        }

        private DateTime time;

        public DateTime Time
        {
            get { return time; }
            set { time = value; }
        }
    }

2.代码块：

    /// <summary>
    /// 功能操作类
    /// </summary>
    public partial class Form1 : Form
    {
        public Form1()
        {
            InitializeComponent();
        }

        string He = "Thread_test";

        TestModue t = new TestModue();
        private void button1_Click(object sender, EventArgs e)
        {
            //无参线程
            Thread t1 = new Thread(new ThreadStart(H1));
            t1.Start();
            //有参线程[单个参数]
            Thread t2 = new Thread(new ParameterizedThreadStart(H2));
            t2.Start(He);
            //有参线程[实体]
            Thread t3 = new Thread(new ParameterizedThreadStart(H3));
            t3.Start(t);
        }      

        /// <summary>
        /// 无参线程执行MessageBox
        /// </summary>
        public void H1() 
        {
            string hello = "Hello World";
            MessageBox.Show(hello);
        }

        /// <summary>
        /// 有参线程执行TextBox赋值操作[单个参数]
        /// </summary>
        /// <param name="He"></param>
        public void H2(object He) 
        {
            //委托代理
            if (InvokeRequired)
            {
                Invoke(new MethodInvoker(delegate { H2(He); }));
                return;
            }
            string  he = (string)He;
            this.textBox1.Text = he;
        }

        /// <summary>
        /// 有参线程执行DataGridView赋值操作[实体类]
        /// </summary>
        /// <param name="obj"></param>
        private void H3(object t)
        {
            //委托代理
            if (InvokeRequired)
            {
                Invoke(new MethodInvoker(delegate { H3(t); }));
                return;
            }
            TestModue tt = (TestModue)t;
            List<TestModue> tlist = new List<TestModue>();
            tlist.Add(tt);
            this.dataGridView1.DataSource = tlist;
        }

        //为实体类赋值
        private void Form1_Load(object sender, EventArgs e)
        {
            t.Id = 1;
            t.Old = 22;
            t.Sex = "男";
            t.Time = DateTime.Now;
        }      
    }
