跨线程更新UI的几种方法

1.跨类跨线程更新UI方法1

    1.0 UI界面代码

public partial class Form1 : Form
    {
        private Thread myThread;

        public Form1()
        {
            InitializeComponent();
        }

        private void button1_Click(object sender, EventArgs e)
        {
            TextBox[] myTextBox = new TextBox[] { textBox1, textBox2, textBox3 };
            Class1 myClass = new Class1();
            #region 开启UI更新线程方法1

            myThread = new Thread(new ThreadStart(delegate { myClass.UpdateUI(myTextBox); }));
            myThread.Start();

            #endregion 开启UI更新线程方法1

            #region 开启UI更新线程方法2

            //myThread = new Thread(new ParameterizedThreadStart(myClass.UpdateUI));
            //myThread.Start(myTextBox);

            #endregion 开启UI更新线程方法2
            //对于不同类型的多个参数，可以使用object[](或其他)
        }

        private void Form1_FormClosed(object sender, FormClosedEventArgs e)
        {
            myThread.Abort();
        }
    }

    1.1 线程类

internal class Class1
    {
        public void UpdateUI(object temp)
        {
            TextBox[] tempTextBox = temp as TextBox[];
            while (true)
            {
                try
                {
                    foreach (TextBox myTextBox in tempTextBox)
                    {
                        if (myTextBox.InvokeRequired)
                        {
                            myTextBox.Invoke(new MethodInvoker(delegate { myTextBox.Text = DateTime.Now.ToLongTimeString(); }));
                        }
                        else
                        {
                            myTextBox.Text = null;
                        }
                    }
                    //for (int i = 0; i < text.Length; i++)
                    //{
                    //    if (text[i].InvokeRequired)
                    //    {
                    //        text[i].Invoke(new MethodInvoker(delegate { text[i].Text = DateTime.Now.ToLongTimeString(); }));
                    //    }
                    //    else
                    //    {
                    //        text[i].Text = null;
                    //    }
                    //}
                }
                catch
                { }
            }
        }
    }
