如何?WPF窗口-最大化，没有大小调整/移动

I'm trying to make a WPF window that opens already maximized, with no resize/move (in systemmenu, nor in border). It should be maximized all the time, except when the user minimize it.

我正在尝试创建一个WPF窗口，该窗口已经最大化打开，没有调整/移动(在systemmenu中，也没有边框中)。它应该一直最大化，除非用户最小化它。

I tried to put WindowState="Maximized" and ResizeMode="CanMinimize", but when window opens, it covers the task bar (i don't want it).

我试图将WindowState="Maximized"和ResizeMode=" can最小化"放在窗口打开时，它会覆盖任务栏(我不想要它)。

I have an hook to WndProc that cancels the SC_MOVE and SC_SIZE. I also can make this control with conditions in WndProc like "if command is restore and is minimized, restore, else, block" and so on.

我有一个与WndProc的挂钩，它取消了SC_MOVE和SC_SIZE。我还可以使用WndProc中的条件来做这个控件，比如“if命令是恢复的，并且最小化了，恢复了，否则，块”等等。

But my point is if we have another way to make it. Thankz for read guys =)

但我的观点是如果我们有另一种方法。谢谢大家阅读=)

It is necessary to write WindowState="Maximized" ResizeMode="NoResize" in xaml of your window:

需要在窗口的xaml中写入WindowState="Maximized" ResizeMode="NoResize":

<Window x:Class="Miscellaneous.EditForm"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    Title="Edit Form" WindowState="Maximized" ResizeMode="NoResize"></Window>

    public Window1()
    {
         InitializeComponent();

          this.SourceInitialized += Window1_SourceInitialized;
    }

    private void Window1_SourceInitialized(object sender, EventArgs e)
    {
        WindowInteropHelper helper = new WindowInteropHelper(this);
        HwndSource source = HwndSource.FromHwnd(helper.Handle);
        source.AddHook(WndProc);
    }

    const int WM_SYSCOMMAND = 0x0112;
    const int SC_MOVE = 0xF010;

    private IntPtr WndProc(IntPtr hwnd, int msg, IntPtr wParam, IntPtr lParam, ref bool handled)
    {

        switch (msg)
        {
            case WM_SYSCOMMAND:
                int command = wParam.ToInt32() & 0xfff0;
                if (command == SC_MOVE)
                {
                    handled = true;
                }
                break;
            default:
                break;
        }
        return IntPtr.Zero;
    }

As Tergiver pointed out, this is not possible in a purely WPF manner. You have to use P/Invoke. As for why the window covers the taskbar when it opens, I think you are messing up some required calls by canceling SC_MOVE and SC_SIZE. Maybe you should cancel those calls after the window has been loaded.

正如tergiving指出的，这是不可能的，仅仅以WPF的方式。您必须使用P/Invoke。至于为什么窗口在打开时覆盖任务栏，我认为取消SC_MOVE和SC_SIZE会使一些必需的调用变得混乱。也许您应该在窗口加载后取消那些调用。

WindowState="Maximized"
ResizeMode="NoResize"
WindowStyle="None"

WindowStyle="None" do what you want, but... you lose the window title, close button and have other problems.

WindowStyle="None"做你想做的事，但是…你失去窗口标题，关闭按钮和其他问题。

Visit WindowStyle="None" some problems
