请问vc.net怎样添加已有的.cs文件

[xinustc]

想通过实例学习，可是连运行都不会 汗...
如果直接打开则编译不用，通过新建项目，却不知道怎么添加.cs文件，高手莫笑

[宝_爸]

cs是C#的源文件，不是VC++的源文件。

[xinustc]

我就是要编译c sharp啊

[Dobzhansky]

要编译 c sharp, 建立 c# 的工程啊, visual studio 不是只支持 vc 一种工程类型的

[chensan]

你可能没有安装完整，只安装vc的工程。

现在加进去了 但是无法编译通过 是版本的问题 已有的程序是vc2002编译的 我想把它在vc2008下编译
不知道怎么弄- -

程序很简单 就一个cs文件：
form.cs

VC是不可能编译C#代码的...虽然.NET支持多语言但是不支持混合语言，这点你要搞清楚...
