我要开发C＃.NET应用程序，但首先我需要检查 该安装.NET Framework，因为我不希望用户看到任何错误。 那么，有没有VC ++ code，只有使用MFC静态库中，以检查是否安装了.NET Framework？

I want to develop a .NET application in c# but first i need to check that the .NET framework is installed , because i don't want user see any error. so is there any vc++ code that only use MFC in a static Library to check if .NET framework is installed ?

推荐答案

您可以使用注册表来查看.NET Framework和它的版本，要么你使用 VC ++ 或其他语言，可以处理注册。

You can use the registry to check about .net framework and it's version, Either you you use VC++ or some other language that can handle registry..

检查Micrsoft知识库文章 - 如何确定哪些版本和在Microsoft .NET Framework的服务包级别安装

有关于SO螺纹。

另一种是使用Signum.Utilities库从SignumFramework（至极，你可以使用独立的），你可以得到它很好的，没有与注册表自行处理。

Another one is using the Signum.Utilities library from SignumFramework (wich you can use stand-alone), you can get it nicely and without dealing with the registry by yourself.

编辑：查看此code项目的文章 - 的安装设备??? 上，同时还使用了注册表.NET框架来获取框架安装或不..

Check this code project article - Is .NET Framework installed on this machine???, it is also using registry to get the framework installed or not..
