推荐答案
Windows 10 操作系统版本值位于此字符串属性中:
Windows.System.Profile.AnalyticsInfo.VersionInfo.DeviceFamilyVersion
The Windows 10 OS version value is located in this string property:
Windows.System.Profile.AnalyticsInfo.VersionInfo.DeviceFamilyVersion
它返回类似2814750438211613"的字符串值.
要将这个长数字转换为可读格式，请使用:
It returns string value like "2814750438211613".
To convert this long number to readable format use this:
string sv = AnalyticsInfo.VersionInfo.DeviceFamilyVersion;
ulong v = ulong.Parse(sv);
ulong v1 = (v & 0xFFFF000000000000L) >> 48;
ulong v2 = (v & 0x0000FFFF00000000L) >> 32;
ulong v3 = (v & 0x00000000FFFF0000L) >> 16;
ulong v4 = v & 0x000000000000FFFFL;
string version = $"{v1}.{v2}.{v3}.{v4}"; // == 10.0.10240.16413
