我浏览了很多不同的论坛，但我找不到办法。我想从任务栏隐藏外部应用程序图标，但没有最小化应用程序。我不知道从哪里开始，或者怎么做。任何帮助将不胜感激。
注意隐藏外部应用程序图标，而不是我的表单图标。

您可以使用ShowWindow功能执行此操作。这是一个小样本，它将隐藏任务栏中正在运行的“calc.exe”。

没有非常简单的方法可以做到这一点。使顶层窗口不显示在任务栏中的方法是：
WS_EX_TOOLWINDOW扩展窗口样式。你可以这样做，但它会改变窗口的外观。ITaskbarList::DeleteTab传递窗口句柄。虽然这会起作用，但我相信在某些情况下，任务栏按钮会返回。基本上，你试图做的是违反规则。如果系统不易使您篡改其他应用程序，请不要感到惊讶。

Form类提供ShowInTaskbar属性。将其设置为false，最好在InitializeComponent之后的构造函数中，winform应用程序将不会显示在Windows任务栏中。
public MyForm()
{
InitializeComponent();
this.ShowInTaskbar = false;
}
