WinForm UI interface design routine - multi thread access UI control

Here we discuss two kinds of multi-threaded access UI Control method , Update after thread completion Lable Control

Here's the picture , The first way is way 1 Button press , Thread running , And update the label

The second method is to press 2 Button , Thread running , Update when done label

  newly build winform Project procedures , The layout is as above , You can use no color matching , Simple

quote

using System.Threading;

  The first method ： Use delegate and invoke To call the control from other threads

  When a control of InvokeRequired When the attribute value is true , It indicates that a thread other than creating it wants to access it , So we judge this attribute to update label Value

 private void button1_Click(object sender, EventArgs e)
        {
            Thread thread1 = new Thread(new ParameterizedThreadStart(UpdateLabel));
            thread1.Start(" to update label");
        }
        private void UpdateLabel(object str)
        {
            if (label1.InvokeRequired)
