• dotnet 获取用户设备安装了哪些 .NET Framework 框架


    从注册表可以拿到当前用户安装的 .NET Framework 版本,本文告诉大家如何解析这些信息

    在注册表的当前设备的 SOFTWAREMicrosoftNET Framework SetupNDP 可以拿到在设备安装的 .NET Framework 版本

    大概从注册表拿到的数据就是这样

    v2.0.50727=.NET Framework 2.0 SP2; v3.0=.NET Framework 3.0 SP2; v3.5=.NET Framework 3.5 SP1; v4 Client=.NET Framework 4.5 Client Profile; v4 Full=.NET Framework 4.5; 
    

    本文主要告诉大家如何从上面的字符串解析出用户安装了哪些 .NET Framework 版本

    各个版本的 .NET Framework 依赖的系统请看.NET Framework Versions and Dependencies
