C# 抓取螢幕縮放比例

using Microsoft.Win32;

public static int DefaultscalingFactor = 96;
public static int scalingFactor = 0;

//取得目前的數值
var reg_url = "Control Panel\\Desktop\\WindowMetrics";
scalingFactor = int.Parse(Registry.CurrentUser.OpenSubKey(reg_url).GetValue("AppliedDPI").ToString());

//螢幕縮放比例 

scale = scalingFactor / DefaultscalingFactor;
