使图形元素“像码头一样”
具体来说，我尝试将我的元素重叠在所有内容之上，包括桌面，类似于 Windows 中的任务栏。我有一个看起来有点像选项卡的 Windows 窗体控件。它的宽度约为 50 像素，长度约为 150 像素。我想做的是让该控件出现在所有窗口的前面，包括桌面本身。我说“类似停靠”是因为我相信停靠会推动窗口（因此，如果我的选项卡停靠了，它将推动任何全屏应用程序窗口超过 50 像素），这不是我想要做的。我希望我的选项卡覆盖在所有内容之上。我能想到的最接近的例子是Winamp。 Winamp 可以停靠在屏幕顶部，并且始终位于任何应用程序的顶部。
在 C# 中如何做到这一点？
Specifically, what I am try to is overlap my element on top of everything, including the desktop, similar to the taskbar in Windows. I have a Windows Form Control that looks kind of like a tab. its like 50px wide by like 150px in length. What I would like to do is have that control appear in front of all windows, including the desktop itself. I say "dock-like" because I belive docking pushes windows over (so if my tab was docked, it would push any full screen application window over 50px), which is not what I'm trying to do. I want my tab to overlay on top of everything. The closest example I can think of is Winamp. Winamp can dock to the top of the screen and it is always on top of any application.
how can do this in C#?

System.Windows.Forms.Form有一个属性TopMost，它将使窗体保持在其他窗口的顶部。Winamp 的“捕捉”行为可以通过使用窗体的
Move事件来实现 - 当窗体移动到足够靠近屏幕边缘时，以编程方式设置位置，使其位于屏幕上边缘。System.Windows.Forms.Formhas a property,TopMost, which will cause the form to stay on top of other windows.The "snapping" behavior of Winamp can be implemented by using the
Moveevent of the form--when the form is moved close enough to the edge of the screen, programatically set the position so that it's on the edge.
