如何查看.net framework 版本

以windows 2016 standard版本为例

通过注册表查看，找到 .NET Framework 注册表信息所在的位置：HKEY_LOCAL_MACHINESOFTWAREMicrosoftNET Framework SetupNDPv4Full

查看release的数值，394802，并对照一下表格：

Value of the Release DWORD	Version
378389	.NET Framework 4.5
378675	.NET Framework 4.5.1 installed with Windows 8.1 or Windows Server 2012 R2
378758	.NET Framework 4.5.1 installed on Windows 8, Windows 7 SP1, or Windows Vista SP2
379893	.NET Framework 4.5.2
On Windows 10 systems only: 393295 On all other OS versions: 393297	.NET Framework 4.6
On Windows 10 November Update systems only: 394254 On all other OS versions: 394271	.NET Framework 4.6.1
On Windows 10 Anniversary Update and Windows Server 2016: 394802 On all other OS versions: 394806	.NET Framework 4.6.2
On Windows 10 Creators Update only: 460798 On all other OS versions: 460805	.NET Framework 4.7
On Windows 10 Fall Creators Update only: 461308 On all other OS versions: 461310	.NET Framework 4.7.1
On Windows 10 April 2018 Update only: 461808 On all other OS versions, including Windows 10 October 2018 Update: 461814	.NET Framework 4.7.2

也可查看version的数值，4.6.01586，但是貌似意义不大。
