亚当，

欢迎来到MSDN论坛.

对于Visual Studio 2008产品，它们是:

Visual Studio 2008 Express产品(VB.NET，C#，C ++，VWD)
Visual Studio 2008标准版
Visual Studio 2008专业版
Visual Studio 2008团队系统(体系结构，数据库，开发，测试，团队套件)

For Visual Studio 2008 products, they are:

Visual Studio 2008 Express products (VB.NET, C#, C++, VWD)
Visual Studio 2008 Standard Edition
Visual Studio 2008 Professional Edition
Visual Studio 2008 Team System (Architecture, Database, Development, Test, Team Suite)

对于VS2008 Professional的升级版，这意味着您可能会从销售中受益.

  这并不意味着您可以将Visual Studio 2008 Express产品升级到Visual Studio 2008 Professional Edition.它们是两种产品.

 It doesn't mean that you can upgrade Visual Studio 2008 Express products to Visual Studio 2008 Professional Edition. They are two products.
