C# AppBar多监视器

我制作了一个简单的应用程序条，屏幕顶部只有一个标签，可以缩小桌面，但我在让它出现在第二个显示器上时遇到了麻烦。我一直在四处寻找，但我找到的一切都是为了WPF。这些很可能是我犯错误的地方，但是如果您需要查看任何其他代码，请告诉我

private void InitializeComponent()
{
    this.ClientSize = new System.Drawing.Size(SystemInformation.WorkingArea.Width, -1);
    this.FormBorderStyle = System.Windows.Forms.FormBorderStyle.FixedToolWindow;
    this.Name = "MainForm";
    this.Text = "AppBar";
    this.Closing += new System.ComponentModel.CancelEventHandler(this.OnClosing);
    this.Load += new System.EventHandler(this.OnLoad);
    this.BackColor = Color.Green;
    this.Padding = new Padding(0, 0, 0, 0);
    Label label1 = new Label();
    label1.Text = "TEXT";
    label1.Width = 270;
    label1.Margin = new Padding(0,0,0,0);
    label1.Padding = new Padding(0,0,0,0);
    label1.TextAlign = ContentAlignment.MiddleCenter;
    label1.ForeColor = Color.White;
    label1.Font = new Font(FontFamily.GenericSansSerif, 12,FontStyle.Regular);
    label1.Location = new Point((SystemInformation.WorkingArea.Width - 270) / 2, 0);
    this.Controls.Add(label1);
}

private void ABSetPos()
{
    APPBARDATA abd = new APPBARDATA();
    abd.cbSize = Marshal.SizeOf(abd);
    abd.hWnd = this.Handle;
    abd.uEdge = (int)ABEdge.ABE_TOP;

    if (abd.uEdge == (int)ABEdge.ABE_LEFT || abd.uEdge == (int)ABEdge.ABE_RIGHT)
    {
        abd.rc.top = 0;
        abd.rc.bottom = SystemInformation.PrimaryMonitorSize.Height;
        if (abd.uEdge == (int)ABEdge.ABE_LEFT)
        {
            abd.rc.left = 0;
            abd.rc.right = Size.Width;
        }
        else
        {
            abd.rc.right = SystemInformation.PrimaryMonitorSize.Width;
            abd.rc.left = abd.rc.right - Size.Width;
        }

    }
    else
    {
        abd.rc.left = 0;
        abd.rc.right = SystemInformation.PrimaryMonitorSize.Width;
        if (abd.uEdge == (int)ABEdge.ABE_TOP)
        {
            abd.rc.top = 0;
            abd.rc.bottom = Size.Height;
        }
        else
        {
            abd.rc.bottom = SystemInformation.PrimaryMonitorSize.Height;
            abd.rc.top = abd.rc.bottom - Size.Height;
        }
    }

通过迭代

屏幕.AllScreens

数组，可以使用不同的屏幕。例如，以下是如何获得第一个非主监视器：

Screen nonPrimaryScreen = Screen.AllScreens.FirstOrDefault(x => !x.Primary);

然后，无论您在哪里使用

SystemInformation.WorkingArea

（始终使用主屏幕），都可以使用：

nonPrimaryScreen.WorkingArea

假设

非主屏幕！=空

。。。当然

编辑：

不要复制代码，而是使其更通用：

public static Rectangle GetWorkingArea() {
    if (UseWantsItOnPrimaryScreen) {
        return SystemInformation.WorkingArea;
    }
    else {
        return Screen.AllScreens.FirstOrDefault(x => !x.Primary).WorkingArea;
    }
}

您可以计算将AppBar移动到第二个监视器的正确公式，而无需使用除

PrimaryMonitorSize

以外的任何东西。例如，对于第二个监视器上的左侧AppBar，您可以使用：

if (abd.uEdge == (int)ABEdge.ABE_LEFT)
{
     abd.rc.left = SystemInformation.PrimaryMonitorSize.Width;
     abd.rc.right = SystemInformation.PrimaryMonitorSize.Width + Size.Width;
}

所以我必须写两个版本的代码，一个是SystemInformation.WorkingArea，另一个是nonPrimaryScreen.WorkingArea？不。。您可以通过使用

矩形

使其更通用。我会编辑我的答案。好的，但这会在一个屏幕上还是另一个屏幕上，或者两个屏幕上？问题是，我不知道是否在程序运行时将矩形从监视器1更改为监视器2，它是否会注意到，或者appbar是否已经创建，而没有注意到监视器2的更改。否。。我没有用勺子喂你。我给了你一个例子，你可以把它插入你的代码库的其他部分。我不知道你的代码库是什么样子的。使用泛型函数。。每次用户更改“主屏幕或非主屏幕”选项时调用它。我发现，您的代码很有用，但我花了一些时间在程序中实现它，因为我不习惯Windows Shell编程。API中的示例代码也很有帮助：。我无法从一个可执行文件中生成2个AppBar，尽管它是多线程的，所以我让它在Monitor2中运行，如果相同的进程已经在运行（可能在monitor 1中）。请提供代码示例之外的其他说明。此示例支持更多屏幕以显示appbar。主要更改如下：此.GetScreenObject（ScreenName）部分。只需定义，appbar从所选屏幕的位置。当您在垂直屏幕上使用-1080时，它是功能性的。这是getscreenobject（其他特殊）的示例，只需返回屏幕对象liek screen.PrimaryScreen或其他，然后在appbar位置使用它。

private Screen GetScreenObject(String Name)
{
    logger.Info(GlobalModulename + "@ ScreenList::looking for screen:"+Name);
    if ((Name == "Primary"))
    {
        bool ExpectedParameter = true;
        foreach (var screen in Screen.AllScreens)
        {
            // For each screen, add the screen properties to a list box.
            logger.Info(GlobalModulename + "@ ScreenList::("+screen.DeviceName.ToString()+")Primary Screen: " + screen.Primary.ToString());
            if (screen.Primary==ExpectedParameter)
            {
                return screen;
            }
        }
    }
    if ((Name == "Secondary"))
    {
        bool ExpectedParameter = false;
        foreach (var screen in Screen.AllScreens)
        {
            // For each screen, add the screen properties to a list box.
            logger.Info(GlobalModulename + "@ ScreenList::(" + screen.DeviceName.ToString() + ")Primary Screen: " + screen.Primary.ToString());
            if (screen.Primary == ExpectedParameter)
            {
                return screen;
            }
        }
    }

    // konkretni jmeno obrazovky tak jak je to v systemu
    try
    {
        foreach (var screen in Screen.AllScreens)
        {
            // For each screen, add the screen properties to a list box.
            logger.Info("UEFA_Core @ ScreenList::Device Name: " + screen.DeviceName);
            logger.Info("UEFA_Core @ ScreenList::Bounds: " + screen.Bounds.ToString());
            logger.Info("UEFA_Core @ ScreenList::Type: " + screen.GetType().ToString());
            logger.Info("UEFA_Core @ ScreenList::Working Area: " + screen.WorkingArea.ToString());
            logger.Info("UEFA_Core @ ScreenList::Primary Screen: " + screen.Primary.ToString());
            if (screen.DeviceName == Name) return screen;
        }

    }
    catch { }

            logger.Info("UEFA_Core @ ScreenList::Device Name: " + screen.DeviceName);

            logger.Info("UEFA_Core @ ScreenList::Primary Screen: " + screen.Primary.ToString());
            if (screen.DeviceName.Contains(Name)) return screen;
        }

    }

    return Screen.PrimaryScreen;
}

if (abd.uEdge == (int)ABEdge.ABE_LEFT)
{
     abd.rc.left = SystemInformation.PrimaryMonitorSize.Width;
     abd.rc.right = SystemInformation.PrimaryMonitorSize.Width + Size.Width;
