有关MSDN帮助文档的问题？

Question

我的MSDN帮助文档存在这样一个问题：上面的某些示例代码只有VB.NET版本的，没有c#版本的，比如System.Windows.Forms.BindingSource的示例。我还是喜欢c#版的，VB不太喜欢!
我又重装了一遍MSDN，把所有的语言都装上，还是这样！
不知道大家的MSDN是不是存在这样的情况？

Answer 1

没遇到过，在MSDN的帮助页面里是可以过滤语言的

Answer 2

我知道你的意思，但即使我把语言筛选器的所有语言都选上，还是只有VB.NET示例，比如System.Windows.Forms.BindingSource的示例

Answer 3

难道大家的MSDN中的每一个示例都有c++,c#,VB.NET,Jsript等各种语言版本吗？

Answer 4

不是所有的示例都有全部的语言的。MSDN也不一定是绝对完整的，不过你可以试试把你没有C#示例的HELP地址帖出来让我们对一下。

Answer 5

ms-help://MS.VSExpressCC.v80/MS.NETFramework.v20.chs/cpref17/html/T_System_Windows_Forms_BindingSource.htm这个就是System.Windows.Forms.BindingSource的示例,没有c#版的
