How can I get a screen resolution of Device (Windows Phone)

Question

如何从设置中获取设备的屏幕分辨率（Windows Phone）？

Answer 1

public void GetScreenResolution()  
{  
     string ScreenWidth = Application.Current.Host.Content.ActualWidth.ToString();  
     string ScreenHeight = Application.Current.Host.Content.ActualHeight.ToString();  
     MessageBox.Show(ScreenWidth + "*" + ScreenHeight);  
}  

Answer 2

This may be a better way to know what screen resolution is your app running on.

if(App.Current.Host.Content.ScaleFactor == 100)
{
  // WVGA
}
else if (App.Current.Host.Content.ScaleFactor == 160)
{
  // WXGA
}
else if (App.Current.Host.Content.ScaleFactor == 150)
{
  // 720p
}

Answer 4

This actually requires a combination of @Dmitriy Reznik and @Paras Wadehra 's answers, as the dimensions exposed by Host.Content are the unscaled dimensions.

var content = App.Current.Host.Content;

var screenResolution = new Size(
    content.ActualWidth*content.ScaleFactor/100,
    content.ActualHeight*content.ScaleFactor/100);
