Wie kann ich die Windows-Taskleiste von „Einblenden“ auf „Automatisch ausblenden“ umschalten/umschalten (und umgekehrt)?

Hier sind die Funktionen, die ich verwende:

[DllImport("user32.dll", CharSet = CharSet.Auto)]
public static extern IntPtr FindWindow(string strClassName, string strWindowName);

[DllImport("shell32.dll")]
public static extern UInt32 SHAppBarMessage(UInt32 dwMessage, ref APPBARDATA pData);

public enum AppBarMessages
{
    New              = 0x00,
    Remove           = 0x01,
    QueryPos         = 0x02,
    SetPos           = 0x03,
    GetState         = 0x04,
    GetTaskBarPos    = 0x05,
    Activate         = 0x06,
    GetAutoHideBar   = 0x07,
    SetAutoHideBar   = 0x08,
    WindowPosChanged = 0x09,
    SetState         = 0x0a
}

[StructLayout(LayoutKind.Sequential)]
public struct APPBARDATA
{
    public UInt32 cbSize;
    public IntPtr hWnd;
    public UInt32 uCallbackMessage;
    public UInt32 uEdge;
    public Rectangle rc;
    public Int32 lParam;
}

public enum AppBarStates
{
    AutoHide    = 0x01,
    AlwaysOnTop = 0x02
}

/// <summary>
/// Set the Taskbar State option
/// </summary>
/// <param name="option">AppBarState to activate</param>
public void SetTaskbarState(AppBarStates option)
{
    APPBARDATA msgData = new APPBARDATA();
    msgData.cbSize = (UInt32)Marshal.SizeOf(msgData);
    msgData.hWnd = FindWindow("System_TrayWnd", null);
    msgData.lParam = (Int32)(option);
    SHAppBarMessage((UInt32)AppBarMessages.SetState, ref msgData);
}

/// <summary>
/// Gets the current Taskbar state
/// </summary>
/// <returns>current Taskbar state</returns>
public AppBarStates GetTaskbarState()
{
    APPBARDATA msgData = new APPBARDATA();
    msgData.cbSize = (UInt32)Marshal.SizeOf(msgData);
    msgData.hWnd = FindWindow("System_TrayWnd", null);
    return (AppBarStates)SHAppBarMessage((UInt32)AppBarMessages.GetState, ref msgData);
}

Wenn der obige Code implementiert ist, stellen Sie die Taskleiste einfach so ein, dass sie automatisch ausgeblendet wird:SetTaskbarState(AppBarStates.AutoHide);

Holen Sie sich den aktuellen Status durch:

AppBarStates currentState = GetTaskbarState();

Ich folgte der @Quispie-Antwort, aber es funktionierte zunächst nicht in Windows 10, gab mir aber die Grundlage und Quelle, um es zu lösen (also Kudos) und auch http://www.pinvoke.net/.

Ausblenden der Taskleiste

Es handelt sich eher um ein Problem mit der WIN32-API als um C#. Sie können dies verwenden (muss natürlich in Punktnetz übersetzt werden), um die Taskleiste auszublenden.

Sie können http://www.pinvoke.net verwenden, um die WIN32-API-Aufrufe in dot net zu übersetzen.

Automatisches Ausblenden der Taskleiste einstellen

Sie können dies erreichen, indem Sie die Registrierung mit den hier beschriebenen Schlüsseln manipulieren.

Es sollte eine leichte Aufgabe sein. Viel Glück.
