推荐答案

这不是一个好主意，但是...您要做的就是更改表单的ShowInTaskbar属性.麻烦的是，当您更改它们时，可能会导致屏幕闪烁.我可能会做的事情(默认情况下对我所有的子窗体都做)将仅将主窗体设置为ShowInTaskbar = true，其他所有窗体都设置为false.这样，您的应用程序只会在任务栏上显示一个图标.麻烦的是，如果您实际上是在为主窗体调用隐藏"，则任务栏图标也会消失.

It''s not a brilliant idea, but...all you have to do is change the ShowInTaskbar property of the forms. The hassle is that it will probably cause a screen flicker when you change them. What I would probably do (and do by default for all my sub forms) is set only the main form to ShowInTaskbar = true, all the others get false. That way you app only ever shows a single icon on the taskbar. The hassle is that if you are actually calling Hide for the main form, the taskbar icon will disappear as well.

private void btnShowChild_clicked(object sender, eventArgs e)
        {
            
                ChildForm obj = new ChildForm();
                obj.Show(); // will show the child form window
                this.Hide(); // hide parent window
            
        }
