_MSC_VER is what you need. You can also examine visualc.hpp in any recent boost install for some usage examples.

Some values for the more recent versions of the compiler are:

MSVC++ 11.0 _MSC_VER = 1700 (Visual Studio 2012)
MSVC++ 10.0 _MSC_VER = 1600 (Visual Studio 2010)
MSVC++ 9.0  _MSC_VER = 1500 (Visual Studio 2008)
MSVC++ 8.0  _MSC_VER = 1400 (Visual Studio 2005)
MSVC++ 7.1  _MSC_VER = 1310 (Visual Studio 2003)
MSVC++ 7.0  _MSC_VER = 1300
MSVC++ 6.0  _MSC_VER = 1200
MSVC++ 5.0  _MSC_VER = 1100

The version number above of course refers to the major version of your Visual studio you see in the about box, not to the year in the name.

cl.exe /? will give a hint of the used version

使用时的例子：

#if (_MSC_VER >= 1500 && _MSC_VER < 1600)
   // ... Do VC9/Visual Studio 2008 specific stuff
#endif
