c# - Windows 10 中虚拟桌面的编程控制

Question

我喜欢 Windows 10 现在支持内置虚拟桌面，但我想添加/修改一些功能(例如，强制在所有桌面上显示一个窗口、使用热键启动任务 View ，有每个显示器的桌面等)

我搜索了应用程序和开发人员引用来帮助我自定义桌面，但没有成功。

我应该从哪里开始？我正在寻找 Windows API 函数(理想情况下，可以从 C# 应用程序调用)，这些函数将使我能够以编程方式访问操作虚拟桌面及其中的窗口。

Windows SDK Support Team Blog发布了C# demo to switch Desktops通过IVirtualDesktopManager:

[ComImport, InterfaceType(ComInterfaceType.InterfaceIsIUnknown), Guid("a5cd92ff-29be-454c-8d04-d82879fb3f1b")]
[System.Security.SuppressUnmanagedCodeSecurity]
public interface IVirtualDesktopManager
{
[PreserveSig]
int IsWindowOnCurrentVirtualDesktop(
    [In] IntPtr TopLevelWindow,
    [Out] out int OnCurrentDesktop
    );
[PreserveSig]
int GetWindowDesktopId(
    [In] IntPtr TopLevelWindow,
    [Out] out Guid CurrentDesktop
    );

[PreserveSig]
int MoveWindowToDesktop(
    [In] IntPtr TopLevelWindow,
    [MarshalAs(UnmanagedType.LPStruct)]
    [In]Guid CurrentDesktop
    );
}

[ComImport, Guid("aa509086-5ca9-4c25-8f95-589d3c07b48a")]
public class CVirtualDesktopManager
{

}
public class VirtualDesktopManager
{
    public VirtualDesktopManager()
    {
        cmanager = new CVirtualDesktopManager();
        manager = (IVirtualDesktopManager)cmanager;
    }
    ~VirtualDesktopManager()
    {
        manager = null;
        cmanager = null;
    }
    private CVirtualDesktopManager cmanager = null;
    private IVirtualDesktopManager manager;

    public bool IsWindowOnCurrentVirtualDesktop(IntPtr TopLevelWindow)
    {
        int result;
        int hr;
        if ((hr = manager.IsWindowOnCurrentVirtualDesktop(TopLevelWindow, out result)) != 0)
        {
            Marshal.ThrowExceptionForHR(hr);
        }
        return result != 0;
    }

    public Guid GetWindowDesktopId(IntPtr TopLevelWindow)
    {
        Guid result;
        int hr;
        if ((hr = manager.GetWindowDesktopId(TopLevelWindow, out result)) != 0)
        {
            Marshal.ThrowExceptionForHR(hr);
        }
        return result;
    }

    public void MoveWindowToDesktop(IntPtr TopLevelWindow, Guid CurrentDesktop)
    {
        int hr;
        if ((hr = manager.MoveWindowToDesktop(TopLevelWindow, CurrentDesktop)) != 0)
        {
            Marshal.ThrowExceptionForHR(hr);
        }
    }
}

它包含用于检测窗口显示在哪个桌面上的 API，并且可以在桌面上切换和移动 Windows。
