多线程不起作用 [英] Multithreading doesn't work

问题描述

我只是试图在两个列表框中并行打印1到100的数字.但是.​​..在第一个列表框之后，只有第二个列表框开始工作.我的编码有任何问题..还是多线程是这样的?请纠正我的错误在编码中.

I just trying to print the 1 to 100 numbers in two list boxes parallel.But...After the first listbox only the second list box starts working.Is my coding has any problem..or multithreading is like this?Please rectify my mistakes in the coding..

private void button1_Click(object sender, EventArgs e)
        {
            int i = 0;
            for (i = 0; i < 100; i++)
            {
                listBox1.Items.Add(i);
                Thread.Sleep(10);
            }
            int j = 0;
            for (j = 0; j < 100;j++)
            {
                listBox2.Items.Add(j);
                Thread.Sleep(10);
            }
          

        }

谢谢

推荐答案

您正在做的不是多线程.

What you are doing is not multithreading.

您的两个for循环是按顺序执行的. Thread.Sleep在添加两个项目之间仅等待10毫秒.这与多线程编程无关.为此，您必须产生两个单独的Thread并从那里进行添加.从非GUI线程访问GUI元素时，请确保使用Control.Invoke.

最好的问候，

Your two for loops are executed sequentially. Thread.Sleep only waits 10 ms in between adding two items. This has nothing to do with multithreaded programming. For that you''d have to produce two separate Threads and do the adding from there. Please make sure to use Control.Invoke when accessing GUI elements from within a non GUI thread.

除了曼弗雷德(Manfred)的解决方案:请参阅我最近的解决方案，其中我将同时使用Control和Dispatcher来解释调用:此编码正确吗? [

In addition to the solution by Manfred: please see my recent solution where I explain invocation using both Control and also Dispatcher: Is this correct coding?[^].
