如何在Windows Phone 8.1上获得缩放分辨率

Question

如何从Windows Phone 8.1上的设备获得缩放分辨率（480×800或480×853）？我有一些测试手机：

• 分辨率 - 480 x 800 - 布局 - 400 x 666
• 分辨率 - 720 x 1280 - 布局 - 514 x 914
• 分辨率 - 1080 x 1920 - 布局 - 490 x 872

Answer 1

你可以使用

    DisplayInformation di = DisplayInformation.GetForCurrentView();
    ResolutionScale rs = di.ResolutionScale;

ResolutionScale将为您提供比例因子： 1. ResolutionScale.Scale100Percent： 2. ResolutionScale.Scale140Percent： 3. ResolutionScale.Scale180Percent：

修改

var rawpixelperview = Windows.Graphics.Display.DisplayInformation.GetForCurrentView().RawPixelsPerViewPixel; 

var Width = Convert.ToInt32(Window.Current.Bounds.Width * rawpixelperview); 
var Height = Convert.ToInt32(Window.Current.Bounds.Height * rawpixelperview); 

if(Width == 480 && Height == 800)
{
    // logic here for this scale
}
else if((Width == 720 && Height == 1280 ) || (Width == 768 && Height == 1280))
{
     // logic here for this scale
}
else
{
     // logic here for this scale
}
