在ｖｓ７下建ＶＣ＃类库，自动生成的AssemblyInfo.cs文件是干什么用的？

让你指定一些信息,编译器会把这些信息放到生成的assembly里面[assembly: AssemblyTitle("")]
[assembly: AssemblyDescription("")]
[assembly: AssemblyConfiguration("")]
[assembly: AssemblyCompany("")]
[assembly: AssemblyProduct("")]
[assembly: AssemblyCopyright("")]
[assembly: AssemblyTrade("")]
[assembly: AssemblyCulture("")] 比如这些从名字就能看出是什么东东了,你也可以参考一下msdn
