如何检查是否安装.NET Framework [C＃/ WPF] [英] How To Check If The .Net Framework Is Installed [C# / WPF]

问题描述

开始我的应用程序（在窗体的Load）我要检查并确保.NET框架（3.5或更高）被安装在计算机上之前 - 如果不是我想提示用户下载并安装它（简单的MessageBox对同一个链接的Microsoft网页将是最好的主意，不是吗？） 因此，这实际上需要执行两个问题...

Before starting my application (on Form Load) I want to check and ensure that the .NET framework (3.5 or higher) are installed on the machine - if not I want to prompt the user to download and install it (simple MessageBox with a INTERNET LINK to the Microsoft WebPage would be the best idea no?) So, this actually entails two questions...

一）如何确定是否已安装了.NET Framework 3.5或更高版本？ （我不相信或仅仅想查找C：\ Program Files文件\ Microsoft.NET文件夹中，似乎容易出错不是吗？） 看到因为这是如此的很关键的，必须有一个很好的方式，在C＃中，以确定哪些版本的.NET的用户他的机器上运行？我只是不知道如何..

a) How do I DETERMINE IF .NET FrameWork 3.5 or higher are installed? (I don't trust or want to just look for the C:\Program Files\Microsoft.NET folder, seems error-prone no?) Seeing as this is so very crucial there must be a nice way in C# to determine what version of .NET the user has running on his machine? I just have no clue how..

二）我如何粘贴的互联网链接（超链接？）的一个消息？因此，如果用户不具备.NET框架（1.1或2.0）安装我可以让他们只需点击链接去下载呢？

b) HOW do I paste an INTERNET LINK (hyperlink?) in a MessageBox? So that if the user does NOT have the .NET framework (1.1 or 2.0) installed I can have them simply click on the link to go download it?

任何帮助/提示将不胜AP preciated。

Any help/hints would be greatly appreciated.

谢谢， 丁

推荐答案

a）你将不得不使用非.NET语言（C ++，VB6等引导程序）（其他海报是正确的 - 如果未安装框架中，.NET程序将无法运行）。一个例子是在这里：

a) You would have to bootstrap the program with a non .NET language (C++, VB6, etc) instead of Form_Load (other posters are correct - if the framework isn't installed, the .NET program won't run). An example is here:

HTTP：//www.$c$cproject.com/KB/ MCPP / DotNetTester.aspx

b）你不能把一个超链接在一个MessageBox，所以你就必须创建自己的弹出式对话框（表格）。 编辑：这表格/对话框将必须在引导程序

b) You can't put a hyperlink in a MessageBox, so you would have to create your own popup dialog (a form). That form / dialog would have to be in the bootstrap program.
