我想知道如何得到任务栏占据的矩形(底部、上、左和右)。我该如何在C#中这样做呢?

下面的函数返回一个矩形数组,每个矩形表示一个停靠的任务栏,并将计数写入其byref参数。如果计数为1,则返回数组的元素0是任务栏占用的矩形。

Public Function FindDockedTaskBars(ByRef DockedRectCounter As Integer) As Rectangle()
    Dim TmpScrn As Screen = Nothing
    Dim LeftDockedWidth As Integer = 0
    Dim TopDockedHeight As Integer = 0
    Dim RightDockedWidth As Integer = 0
    Dim BottomDockedHeight As Integer = 0
    Dim DockedRects(Screen.AllScreens.Count * 4) As Rectangle

    DockedRectCounter = 0

    For Each TmpScrn In Screen.AllScreens
        If Not TmpScrn.Bounds.Equals(TmpScrn.WorkingArea) Then
            LeftDockedWidth = Math.Abs(Math.Abs(TmpScrn.Bounds.Left) - Math.Abs(TmpScrn.WorkingArea.Left))
            TopDockedHeight = Math.Abs(Math.Abs(TmpScrn.Bounds.Top) - Math.Abs(TmpScrn.WorkingArea.Top))
            RightDockedWidth = (TmpScrn.Bounds.Width - LeftDockedWidth) - TmpScrn.WorkingArea.Width
            BottomDockedHeight = (TmpScrn.Bounds.Height - TopDockedHeight) - TmpScrn.WorkingArea.Height

            If LeftDockedWidth > 0 Then
                DockedRects(DockedRectCounter).X = TmpScrn.Bounds.Left
                DockedRects(DockedRectCounter).Y = TmpScrn.Bounds.Top
                DockedRects(DockedRectCounter).Width = LeftDockedWidth
                DockedRects(DockedRectCounter).Height = TmpScrn.Bounds.Height
                DockedRectCounter += 1
            End If
            If RightDockedWidth > 0 Then
                DockedRects(DockedRectCounter).X = TmpScrn.WorkingArea.Right
                DockedRects(DockedRectCounter).Y = TmpScrn.Bounds.Top
                DockedRects(DockedRectCounter).Width = RightDockedWidth
                DockedRects(DockedRectCounter).Height = TmpScrn.Bounds.Height
                DockedRectCounter += 1
            End If
            If TopDockedHeight > 0 Then
                DockedRects(DockedRectCounter).X = TmpScrn.WorkingArea.Left
                DockedRects(DockedRectCounter).Y = TmpScrn.Bounds.Top
                DockedRects(DockedRectCounter).Width = TmpScrn.WorkingArea.Width
                DockedRects(DockedRectCounter).Height = TopDockedHeight
                DockedRectCounter += 1
            End If
            If BottomDockedHeight > 0 Then
                DockedRects(DockedRectCounter).X = TmpScrn.WorkingArea.Left
                DockedRects(DockedRectCounter).Y = TmpScrn.WorkingArea.Bottom
                DockedRects(DockedRectCounter).Width = TmpScrn.WorkingArea.Width
                DockedRects(DockedRectCounter).Height = BottomDockedHeight
                DockedRectCounter += 1
            End If
        End If
    Next
    Return DockedRects
End Function

或者你们中喜欢C#的人可以用这个(注意:此移植代码未经测试)

using System.Drawing;
using System.Windows.Forms;

public Rectangle[] FindDockedTaskBars(ref int DockedRectCounter)
{
    int LeftDockedWidth = 0;
    int TopDockedHeight = 0;
    int RightDockedWidth = 0;
    int BottomDockedHeight = 0;
    Rectangle[] DockedRects = new Rectangle[Screen.AllScreens.Count() * 4]; 

    DockedRectCounter = 0;
    foreach (Screen TmpScrn in Screen.AllScreens)
    {
        if (!TmpScrn.Bounds.Equals(TmpScrn.WorkingArea))
        {
            LeftDockedWidth = Math.Abs(Math.Abs(TmpScrn.Bounds.Left) - Math.Abs(TmpScrn.WorkingArea.Left));
            TopDockedHeight = Math.Abs(Math.Abs(TmpScrn.Bounds.Top) - Math.Abs(TmpScrn.WorkingArea.Top));
            RightDockedWidth = (TmpScrn.Bounds.Width - LeftDockedWidth) - TmpScrn.WorkingArea.Width;
            BottomDockedHeight = (TmpScrn.Bounds.Height - TopDockedHeight) - TmpScrn.WorkingArea.Height;

            if (LeftDockedWidth > 0)
            {
                DockedRects[DockedRectCounter].X = TmpScrn.Bounds.Left;
                DockedRects[DockedRectCounter].Y = TmpScrn.Bounds.Top;
                DockedRects[DockedRectCounter].Width = LeftDockedWidth;
                DockedRects[DockedRectCounter].Height = TmpScrn.Bounds.Height;
                DockedRectCounter += 1;
            }

            if (RightDockedWidth > 0)
            {
                DockedRects[DockedRectCounter].X = TmpScrn.WorkingArea.Right;
                DockedRects[DockedRectCounter].Y = TmpScrn.Bounds.Top;
                DockedRects[DockedRectCounter].Width = RightDockedWidth;
                DockedRects[DockedRectCounter].Height = TmpScrn.Bounds.Height;
                DockedRectCounter += 1;
            }
            if (TopDockedHeight > 0)
            {
                DockedRects[DockedRectCounter].X = TmpScrn.WorkingArea.Left;
                DockedRects[DockedRectCounter].Y = TmpScrn.Bounds.Top;
                DockedRects[DockedRectCounter].Width = TmpScrn.WorkingArea.Width;
                DockedRects[DockedRectCounter].Height = TopDockedHeight;
                DockedRectCounter += 1;
            }
            if (BottomDockedHeight > 0)
            {
                DockedRects[DockedRectCounter].X = TmpScrn.WorkingArea.Left;
                DockedRects[DockedRectCounter].Y = TmpScrn.WorkingArea.Bottom;
                DockedRects[DockedRectCounter].Width = TmpScrn.WorkingArea.Width;
                DockedRects[DockedRectCounter].Height = BottomDockedHeight;
                DockedRectCounter += 1;
            }
        }
    }
    return DockedRects;
}

    private enum TaskBarLocation { TOP, BOTTOM, LEFT, RIGHT}

    private TaskBarLocation GetTaskBarLocation()
    {
        TaskBarLocation taskBarLocation = TaskBarLocation.BOTTOM;
        bool taskBarOnTopOrBottom = (Screen.PrimaryScreen.WorkingArea.Width == Screen.PrimaryScreen.Bounds.Width);
        if (taskBarOnTopOrBottom)
