【已解决】C#中获恰当前任务栏的巨细(宽度和高度）和位置(X,Y) 和 当前屏幕的右下角位置(X,Y) – 均撑持任务栏的下右上左四种模式
在折腾：
C#中如安在右下角添加提示窗口，用于显示打开文件和文件夹
的过程中，需要知道任务栏的高度和位置，才华准确将子窗体显示在右下角。
【解决过程】
1.参考：
How do I get the taskbar’s position and size?
去写了代码：
?
1
Rectangle taskbarRect = Screen.PrimaryScreen.WorkingArea;
然后调试的功效是：
而对应的屏幕辨别率是1680×1050：
对应确当前任务栏是在屏幕下面的：
2.又去测试了其他几种情况：
任务栏是在右边的：
然后调试功效是：
任务栏在上面的：
任务栏在左边的：
3.由此，继续去调试，期间遇到想要设置窗口位置的问题，后来解决了，详参：
【已解决】C#中通过代码转变/设置窗口的位置(Location)
4.最终整理出算法，始终但愿窗口位置显示在屏幕边角，贴近任务栏中是显示时间的阿谁位置：

return new Point(xPos, yPos);
}
private void completeHint_Load(object sender, EventArgs e)
{

}
5.然后，又花时间，整理出来函数，，可以获恰当前屏幕的任务栏的巨细：

【总结】
凡事，还是要靠本身，靠别人还是不靠谱。
