    【问题】

    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：

    screen primaryscreen

    而对应的屏幕分辨率是1680×1050：

    screen resolution 1680x1050

     

    对应的当前任务栏是在屏幕下面的：

    taskbar bottom

    2.又去测试了其他几种情况：

    任务栏是在右边的：

    taskbar right

    然后调试结果是：

    debug result while taskbar right

     

    任务栏在上面的：

    taskbar up

    debug result while taskbar up

     

    任务栏在左边的：

    taskbar left

    debug result while taskbar left

     

    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：

    {
        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：

    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：

        this.Location = crl.getCornerLocation(this.Size);
    }

     

    另，上述所有函数，都已整理至：
