## 1，涉及API ##

GetVersionEx函数原型：

**\[cpp\]** [view plain][] [copy][view plain]

1.  **BOOL** GetVersionEx(POSVERSIONINFO pVersionInformation);

结构OSVERSIONINFOEX定义如下：

**\[cpp\]** [view plain][Link 1] [copy][Link 1]

[![在CODE上查看代码片][CODE]][CODE_CODE] [![派生到我的代码片][ico_fork.svg]][ico_fork.svg 1]

1.  **typedef****struct** \{ 
2.  **DWORD** dwOSVersionInfoSize; //在使用GetVersionEx之前要将此初始化为结构的大小 
3.  **DWORD** dwMajorVersion; //系统主版本号 
4.  **DWORD** dwMinorVersion; //系统次版本号 
5.  **DWORD** dwBuildNumber; //系统构建号 
6.  **DWORD** dwPlatformId; //系统支持的平台 
7.  **TCHAR** szCSDVersion\[128\]; //系统补丁包的名称 
8.  **WORD** wServicePackMajor; //系统补丁包的主版本 
9.  **WORD** wServicePackMinor; //系统补丁包的次版本 
10. **WORD** wSuiteMask; //标识系统上的程序组 
11. **BYTE** wProductType; //标识系统类型 
12. **BYTE** wReserved; //保留,未使用 
13. \} OSVERSIONINFOEX, \*POSVERSIONINFOEX;

在调用函数之前先初始化结构的大小并调用函数，返回true表示成功:

**\[cpp\]** [view plain][] [copy][view plain]

1.  OSVERSIONINFOEX os; 
2.  os.dwOSVersionInfoSize=**sizeof**(os); 
3.  **if**(!GetVersionEx((OSVERSIONINFO \*)&os)) 
4.  \{ 
5.  **return** FALSE; 
6.  \}

函数调用成功以后就可以通过OSVERSIONINFOEX来查看系统的版本信息了。

各个操作系统的版本号列表 如下：

##    2，使用 ##

判断系统版本的代码示例：

**\[cpp\]** [view plain][Link 1] [copy][Link 1]

[![在CODE上查看代码片][CODE]][CODE_CODE] [![派生到我的代码片][ico_fork.svg]][ico_fork.svg 1]

1.  OSVERSIONINFOEX os; 
2.  os.dwOSVersionInfoSize=**sizeof**(OSVERSIONINFOEX); 
3.  **if**(GetVersionEx((OSVERSIONINFO \*)&os)) 
4.  \{ 
5.  **switch**(os.dwMajorVersion) 
6.   \{ 
7.  **case** 5: 
8.  **switch**(os.dwMinorVersion) 
9.   \{ 
10. **case** 0: //Windows 2000 
11. **break**; 
12. **case** 1: //Windows XP
13. **break**; 
14. **case** 2: //Windows Server 2003
15. **break**; 
16.  \} 
17. **case** 6: 
18. **switch**(os.dwMinorVersion) 
19.  \{ 
20. **case** 0: 
21. **if**(os.wProductType==VER\_NT\_WORKSTATION) //Microsoft Windows Vista
22.  \{ 
23.  \} 
24. **else**//Microsoft Windows Server 2008 
25.  \{ 
26.  \} 
27. **break**; 
28. **case** 1: 
29. **if**(os.wProductType==VER\_NT\_WORKSTATION) //Microsoft Windows 7
30.  \{ 
31.  \} 
32. **else**//Microsoft Windows Server 2008 R2
33.  \{ 
34.  \} 
35. **break**; 
36. **case** 2: //Microsoft Windows 7
37. **break**; 
38.  \} 
39. **break**; 
40. **default**: //其他版本
41. **break**; 
42.  \} 
43. \}

操作系统的补丁包版本可以从wServicePackMajor，wServicePackMinor获取。
