确保WPF窗口在屏幕边界内

System.Windows.Forms.Screen 在WPF中工作得非常好,所以我认为WPF的设计者认为用WPF特定的版本来代替它没有任何优势。

当然,你得做坐标变换。下面是一个简单的类来进行转换:

public class ScreenBoundsConverter
{
  private Matrix _transform;

  public ScreenBoundsConverter(Visual visual)
  {
    _transform =
      PresentationSource.FromVisual(visual).CompositionTarget.TransformFromDevice;
  }

  public Rect ConvertBounds(Rectangle bounds)
  {
    var result = new Rect(bounds.X, bounds.Y, bounds.Width, bounds.Height);
    result.Transform(_transform);
    return result;
  }
}

用法示例:

var converter = new ScreenBoundsConverter(this);

foreach(var screen in System.Windows.Forms.Screen.AllScreens)
{
  Rect bounds = converter.ConvertBounds(screen.Bounds);
  ...
}
