활성 화면 크기를 얻으려면 어떻게해야합니까?

내가 찾고있는 System.Windows.SystemParameters.WorkArea것은 현재 창이있는 모니터 와 같습니다 .

설명 : 문제 의 창이 WPF아닙니다 WinForm.

Screen.FromControl, Screen.FromPoint그리고 Screen.FromRectangle이 당신을 도움이 될 것입니다. 예를 들어 WinForms에서는 다음과 같습니다.

class MyForm : Form
{
  public Rectangle GetScreen()
  {
    return Screen.FromControl(this).Bounds;
  }
}

WPF에 해당하는 전화를 모른다. 따라서이 확장 방법과 같은 작업을 수행해야합니다.

static class ExtensionsForWPF
{
  public static System.Windows.Forms.Screen GetScreen(this Window window)
  {
    return System.Windows.Forms.Screen.FromHandle(new WindowInteropHelper(window).Handle);
  }
}

---

이를 사용하여 기본 화면의 데스크탑 작업 공간 경계를 확보 할 수 있습니다.

System.Windows.SystemParameters.WorkArea

이것은 또한 기본 화면의 크기를 얻는 데 유용합니다.

System.Windows.SystemParameters.PrimaryScreenWidth System.Windows.SystemParameters.PrimaryScreenHeight

---

또한 다음이 필요할 수 있습니다.

• SystemParameters.VirtualScreenWidth
• SystemParameters.VirtualScreenHeight

특히 모든 모니터의 크기를 합치 지 않습니다.

WinForms를 사용하지 않고 NativeMethods를 사용하는 솔루션 추가. 먼저 필요한 기본 메소드를 정의해야합니다.

public static class NativeMethods
{
    public const Int32 MONITOR_DEFAULTTOPRIMERTY = 0x00000001;
    public const Int32 MONITOR_DEFAULTTONEAREST = 0x00000002;


    [DllImport( "user32.dll" )]
    public static extern IntPtr MonitorFromWindow( IntPtr handle, Int32 flags );


    [DllImport( "user32.dll" )]
    public static extern Boolean GetMonitorInfo( IntPtr hMonitor, NativeMonitorInfo lpmi );


    [Serializable, StructLayout( LayoutKind.Sequential )]
    public struct NativeRectangle
    {
        public Int32 Left;
        public Int32 Top;
        public Int32 Right;
        public Int32 Bottom;


        public NativeRectangle( Int32 left, Int32 top, Int32 right, Int32 bottom )
        {
            this.Left = left;
            this.Top = top;
            this.Right = right;
            this.Bottom = bottom;
        }
    }


    [StructLayout( LayoutKind.Sequential, CharSet = CharSet.Auto )]
    public sealed class NativeMonitorInfo
    {
        public Int32 Size = Marshal.SizeOf( typeof( NativeMonitorInfo ) );
        public NativeRectangle Monitor;
        public NativeRectangle Work;
        public Int32 Flags;
    }
}

그런 다음 모니터 핸들과 이와 같은 모니터 정보를 얻습니다.

        var hwnd = new WindowInteropHelper( this ).EnsureHandle();
        var monitor = NativeMethods.MonitorFromWindow( hwnd, NativeMethods.MONITOR_DEFAULTTONEAREST );

        if ( monitor != IntPtr.Zero )
        {
            var monitorInfo = new NativeMonitorInfo();
            NativeMethods.GetMonitorInfo( monitor, monitorInfo );

            var left = monitorInfo.Monitor.Left;
            var top = monitorInfo.Monitor.Top;
            var width = ( monitorInfo.Monitor.Right - monitorInfo.Monitor.Left );
            var height = ( monitorInfo.Monitor.Bottom - monitorInfo.Monitor.Top );
        }

ffpf에 추가

Screen.FromControl(this).Bounds

---

창의 배율을주의하십시오 (100 % / 125 % / 150 % / 200 %). 다음 코드를 사용하여 실제 화면 크기를 얻을 수 있습니다.

SystemParameters.FullPrimaryScreenHeight
SystemParameters.FullPrimaryScreenWidth

---

내 첫 번째 창을 열기 전에 화면 해상도를 원했기 때문에 실제로 화면 크기를 측정하기 전에 보이지 않는 창을 여는 빠른 솔루션 (두 창을 모두 열어 두려면 창 매개 변수를 창에 맞게 조정해야 함) 같은 화면-주로 WindowStartupLocation중요합니다)

Window w = new Window();
w.ResizeMode = ResizeMode.NoResize;
w.WindowState = WindowState.Normal;
w.WindowStyle = WindowStyle.None;
w.Background = Brushes.Transparent;
w.Width = 0;
w.Height = 0;
w.AllowsTransparency = true;
w.IsHitTestVisible = false;
w.WindowStartupLocation = WindowStartupLocation.Manual;
w.Show();
Screen scr = Screen.FromHandle(new WindowInteropHelper(w).Handle);
w.Close();

This is a "Center Screen DotNet 4.5 solution", using SystemParameters instead of System.Windows.Forms or My.Compuer.Screen: Since Windows 8 has changed the screen dimension calculation, the only way it works for me looks like that (Taskbar calculation included):

Private Sub Window_Loaded(ByVal sender As System.Object, ByVal e As System.Windows.RoutedEventArgs) Handles MyBase.Loaded
    Dim BarWidth As Double = SystemParameters.VirtualScreenWidth - SystemParameters.WorkArea.Width
    Dim BarHeight As Double = SystemParameters.VirtualScreenHeight - SystemParameters.WorkArea.Height
    Me.Left = (SystemParameters.VirtualScreenWidth - Me.ActualWidth - BarWidth) / 2
    Me.Top = (SystemParameters.VirtualScreenHeight - Me.ActualHeight - BarHeight) / 2         
End Sub

I needed to set the maximum size of my window application. This one could changed accordingly the application is is been showed in the primary screen or in the secondary. To overcome this problem e created a simple method that i show you next:

/// <summary>
/// Set the max size of the application window taking into account the current monitor
/// </summary>
public static void SetMaxSizeWindow(ioConnect _receiver)
{
    Point absoluteScreenPos = _receiver.PointToScreen(Mouse.GetPosition(_receiver));

    if (System.Windows.SystemParameters.VirtualScreenLeft == System.Windows.SystemParameters.WorkArea.Left)
    {
        //Primary Monitor is on the Left
        if (absoluteScreenPos.X <= System.Windows.SystemParameters.PrimaryScreenWidth)
        {
            //Primary monitor
            _receiver.WindowApplication.MaxWidth = System.Windows.SystemParameters.WorkArea.Width;
            _receiver.WindowApplication.MaxHeight = System.Windows.SystemParameters.WorkArea.Height;
        }
        else
        {
            //Secondary monitor
            _receiver.WindowApplication.MaxWidth = System.Windows.SystemParameters.VirtualScreenWidth - System.Windows.SystemParameters.WorkArea.Width;
            _receiver.WindowApplication.MaxHeight = System.Windows.SystemParameters.VirtualScreenHeight;
        }
    }

    if (System.Windows.SystemParameters.VirtualScreenLeft < 0)
    {
        //Primary Monitor is on the Right
        if (absoluteScreenPos.X > 0)
        {
            //Primary monitor
            _receiver.WindowApplication.MaxWidth = System.Windows.SystemParameters.WorkArea.Width;
            _receiver.WindowApplication.MaxHeight = System.Windows.SystemParameters.WorkArea.Height;
        }
        else
        {
            //Secondary monitor
            _receiver.WindowApplication.MaxWidth = System.Windows.SystemParameters.VirtualScreenWidth - System.Windows.SystemParameters.WorkArea.Width;
            _receiver.WindowApplication.MaxHeight = System.Windows.SystemParameters.VirtualScreenHeight;
        }
    }
}

in C# winforms I have got start point (for case when we have several monitor/diplay and one form is calling another one) with help of the following method:

private Point get_start_point()
    {
        return
            new Point(Screen.GetBounds(parent_class_with_form.ActiveForm).X,
                      Screen.GetBounds(parent_class_with_form.ActiveForm).Y
                      );
    }
