C#中获得当前任务栏的大小

【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:

C#中如何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:

 技术分享图片

 

 

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:

 

 技术分享图片

 

任务栏在上面的:

 

 技术分享图片

 

 

 技术分享图片

 

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

    }

 

    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:
