【已解决】C#中获得当前任务栏的大小(宽度和高度）和位置(X,Y) 和 当前屏幕的右下角位置(X,Y) – 均支持任务栏的下右上左四种模式
在折腾：
的过程中，需要知道任务栏的高度和位置，才能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; |
然后调试的结果是：
而对应的屏幕分辨率是1680×1050：
对应的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：
然后调试结果是：
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#中通过代码改变/设置窗口的位置(Location)
4.最终整理出算法，始终希望窗口位置显示在屏幕边角，贴近任务栏中是显示时间的那个位置：

// get current right bottom corner position(X, Y), support four mode: taskbar bottom/right/up/left public Point getCornerLocation() { int xPos = 0, yPos = 0;
if( (Screen.PrimaryScreen.Bounds.Width == Screen.PrimaryScreen.WorkingArea.Width) && (Screen.PrimaryScreen.WorkingArea.Y == 0)) { //taskbar bottom xPos = Screen.PrimaryScreen.WorkingArea.Width - this.Size.Width; yPos = Screen.PrimaryScreen.WorkingArea.Height - this.Size.Height; } else if((Screen.PrimaryScreen.Bounds.Height == Screen.PrimaryScreen.WorkingArea.Height) && (Screen.PrimaryScreen.WorkingArea.X == 0) ) { //taskbar right xPos = Screen.PrimaryScreen.WorkingArea.Width - this.Size.Width; yPos = Screen.PrimaryScreen.WorkingArea.Height - this.Size.Height; } else if((Screen.PrimaryScreen.Bounds.Width == Screen.PrimaryScreen.WorkingArea.Width) && (Screen.PrimaryScreen.WorkingArea.Y > 0) ) { //taskbar up xPos = Screen.PrimaryScreen.WorkingArea.Width - this.Size.Width; yPos = Screen.PrimaryScreen.WorkingArea.Y; } else if ((Screen.PrimaryScreen.Bounds.Height == Screen.PrimaryScreen.WorkingArea.Height) && (Screen.PrimaryScreen.WorkingArea.X > 0)) { //taskbar left xPos = Screen.PrimaryScreen.WorkingArea.X; yPos = Screen.PrimaryScreen.WorkingArea.Height - this.Size.Height; }
return new Point(xPos, yPos); }
private void completeHint_Load(object sender, EventArgs e) { this.Location = getCornerLocation(); } |
5.然后，又花时间，整理出来函数，可以获得当前屏幕的任务栏的大小：

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 |
// get current taskbar size(width, height), support four mode: taskbar bottom/right/up/left public Size getCurTaskbarSize() { int width = 0, height = 0;
if ((Screen.PrimaryScreen.Bounds.Width == Screen.PrimaryScreen.WorkingArea.Width) && (Screen.PrimaryScreen.WorkingArea.Y == 0)) { //taskbar bottom width = Screen.PrimaryScreen.WorkingArea.Width; height = Screen.PrimaryScreen.Bounds.Height - Screen.PrimaryScreen.WorkingArea.Height; } else if ((Screen.PrimaryScreen.Bounds.Height == Screen.PrimaryScreen.WorkingArea.Height) && (Screen.PrimaryScreen.WorkingArea.X == 0)) { //taskbar right width = Screen.PrimaryScreen.Bounds.Width - Screen.PrimaryScreen.WorkingArea.Width; height = Screen.PrimaryScreen.WorkingArea.Height; } else if ((Screen.PrimaryScreen.Bounds.Width == Screen.PrimaryScreen.WorkingArea.Width) && (Screen.PrimaryScreen.WorkingArea.Y > 0)) { //taskbar up width = Screen.PrimaryScreen.WorkingArea.Width; //height = Screen.PrimaryScreen.WorkingArea.Y; height = Screen.PrimaryScreen.Bounds.Height - Screen.PrimaryScreen.WorkingArea.Height; } else if ((Screen.PrimaryScreen.Bounds.Height == Screen.PrimaryScreen.WorkingArea.Height) && (Screen.PrimaryScreen.WorkingArea.X > 0)) { //taskbar left width = Screen.PrimaryScreen.Bounds.Width - Screen.PrimaryScreen.WorkingArea.Width; height = Screen.PrimaryScreen.WorkingArea.Height; }
return new Size(width, height); }
private void completeHint_Load(object sender, EventArgs e) { Size curTaskbarSize = getCurTaskbarSize(); } |
【总结】
凡事，还是要靠自己，靠别人还是不靠谱。
C#中，获得当前任务栏的大小，以及获得当前屏幕的边角（靠近任务栏中时间的那个）位置的相关代码如下：

// get current taskbar size(width, height), support four mode: taskbar bottom/right/up/left public Size getCurTaskbarSize() { int width = 0, height = 0;
if ((Screen.PrimaryScreen.Bounds.Width == Screen.PrimaryScreen.WorkingArea.Width) && (Screen.PrimaryScreen.WorkingArea.Y == 0)) { //taskbar bottom width = Screen.PrimaryScreen.WorkingArea.Width; height = Screen.PrimaryScreen.Bounds.Height - Screen.PrimaryScreen.WorkingArea.Height; } else if ((Screen.PrimaryScreen.Bounds.Height == Screen.PrimaryScreen.WorkingArea.Height) && (Screen.PrimaryScreen.WorkingArea.X == 0)) { //taskbar right width = Screen.PrimaryScreen.Bounds.Width - Screen.PrimaryScreen.WorkingArea.Width; height = Screen.PrimaryScreen.WorkingArea.Height; } else if ((Screen.PrimaryScreen.Bounds.Width == Screen.PrimaryScreen.WorkingArea.Width) && (Screen.PrimaryScreen.WorkingArea.Y > 0)) { //taskbar up width = Screen.PrimaryScreen.WorkingArea.Width; //height = Screen.PrimaryScreen.WorkingArea.Y; height = Screen.PrimaryScreen.Bounds.Height - Screen.PrimaryScreen.WorkingArea.Height; } else if ((Screen.PrimaryScreen.Bounds.Height == Screen.PrimaryScreen.WorkingArea.Height) && (Screen.PrimaryScreen.WorkingArea.X > 0)) { //taskbar left width = Screen.PrimaryScreen.Bounds.Width - Screen.PrimaryScreen.WorkingArea.Width; height = Screen.PrimaryScreen.WorkingArea.Height; }
return new Size(width, height); }
// get current right bottom corner position(X, Y), support four mode: taskbar bottom/right/up/left public Point getCornerLocation() { int xPos = 0, yPos = 0;
if( (Screen.PrimaryScreen.Bounds.Width == Screen.PrimaryScreen.WorkingArea.Width) && (Screen.PrimaryScreen.WorkingArea.Y == 0)) { //taskbar bottom xPos = Screen.PrimaryScreen.WorkingArea.Width - this.Size.Width; yPos = Screen.PrimaryScreen.WorkingArea.Height - this.Size.Height; } else if((Screen.PrimaryScreen.Bounds.Height == Screen.PrimaryScreen.WorkingArea.Height) && (Screen.PrimaryScreen.WorkingArea.X == 0) ) { //taskbar right xPos = Screen.PrimaryScreen.WorkingArea.Width - this.Size.Width; yPos = Screen.PrimaryScreen.WorkingArea.Height - this.Size.Height; } else if((Screen.PrimaryScreen.Bounds.Width == Screen.PrimaryScreen.WorkingArea.Width) && (Screen.PrimaryScreen.WorkingArea.Y > 0) ) { //taskbar up xPos = Screen.PrimaryScreen.WorkingArea.Width - this.Size.Width; yPos = Screen.PrimaryScreen.WorkingArea.Y; } else if ((Screen.PrimaryScreen.Bounds.Height == Screen.PrimaryScreen.WorkingArea.Height) && (Screen.PrimaryScreen.WorkingArea.X > 0)) { //taskbar left xPos = Screen.PrimaryScreen.WorkingArea.X; yPos = Screen.PrimaryScreen.WorkingArea.Height - this.Size.Height; }
return new Point(xPos, yPos); }
private void completeHint_Load(object sender, EventArgs e) { Size curTaskbarSize = getCurTaskbarSize();
this.Location = getCornerLocation(); } |
【后记 2012-09-25】
后来，又添加了，获得当前任务栏的位置的函数。
全部的代码如下：

private void completeHint_Load(object sender, EventArgs e) { Size curTaskbarSize = crl.getCurTaskbarSize(); Point curTaskbarLocation = crl.getCurTaskbarLocation(); this.Location = crl.getCornerLocation(this.Size); } |
