C#如何获得 WINDOWS 版本号

using System;

using System.Runtime.InteropServices;

namespace GetWindowsVersion

{

[ StructLayout( LayoutKind.Sequential )]

public class OSVersionInfo 

{

public int OSVersionInfoSize;

public int MajorVersion;

public int MinorVersion;

}

public class LibWrap

public static extern bool GetVersionEx( [In, Out] OSVersionInfo osvi );

[ DllImport( "kernel32", EntryPoint="GetVersionEx" )] 

public static extern bool GetVersionEx2( ref OSVersionInfo2 osvi ); 

}

public class App

{

public static void Main()

{

Console.WriteLine( " Passing OSVersionInfo as class" );

OSVersionInfo osvi = new OSVersionInfo();

LibWrap.GetVersionEx( osvi );



Console.WriteLine( "Class size: {0} Operation System : {1} Pack: {2}", osvi.OSVersionInfoSize, OpSysName(osvi.MajorVersion, osvi.MinorVersion,osvi.PlatformId),osvi.versionString);

Console.WriteLine("{0}", osvi.PlatformId);



Console.WriteLine( " Passing OSVersionInfo as struct" );

OSVersionInfo2 osvi2 = new OSVersionInfo2();

Console.WriteLine( "Static size: {0} Operation System : {1} Pack: {2}", osvi2.OSVersionInfoSize, OpSysName(osvi2.MajorVersion, osvi2.MinorVersion,osvi2.PlatformId),osvi2.versionString);



}

public static String OpSysName(int MajorVersion,int MinorVersion ,int PlatformId)

{

String str_opn =String.Format("{0}.{1}",MajorVersion,MinorVersion);

switch(str_opn)

{

case "4.0":

return win95_nt40(PlatformId);

case "4.10":

return "Windows 98";

case "4.90":

return "Windows Me";

case "3.51":

return "Windows NT 3.51";

case "5.0":

return "Windwos 2000";

case "5.1":

return "Windwos XP";

case "5.2":

return "Windows Server 2003 family";

default:

return "This windows version is not distinguish!";

}

}

public static String win95_nt40(int PlatformId)

{

switch(PlatformId)

{

case 1:

return "Windows 95";

case 2:

return "Windows NT 4.0";

default:

return "This windows version is not distinguish!";

}

}

}

}

使用GetVersionEx传递例如以下结构来获得此信息

typedef struct _OSVERSIONINFOEX { 

 DWORD dwOSVersionInfoSize;  

DWORD dwMajorVersion; 

 DWORD dwMinorVersion; 

 DWORD dwBuildNumber; 

 DWORD dwPlatformId;  

TCHAR szCSDVersion[128];  

WORD wServicePackMajor; 

 WORD wServicePackMinor;  

WORD wSuiteMask;  //此成员能够用来作为推断home 还是professional的根据

BYTE wProductType; 

 BYTE wReserved;

} OSVERSIONINFOEX, *POSVERSIONINFOEX, *LPOSVERSIONINFOEX;



关于操作系统的其它的信息你都能够在此结构中找到,详细使用參见MSDN的帮助

不怎么用C#,现学现卖给你写了一段代码,(代码中有不合理的地方,自己參照改动,实在没用过C#)例如以下:



主要代码例如以下:

using System.Runtime.InteropServices;



上述结构在C#中定义例如以下:

[ StructLayout( LayoutKind.Sequential )]   

public class OSVersionInfo 

{


public int OSVersionInfoSize;

public int majorVersion; 

public int minorVersion;

public int buildNumber;

public int platformId;



[ MarshalAs( UnmanagedType.ByValTStr, SizeConst=128 )]    

public String versionString;

public Int16  wServicePackMajor;  

public Int16  wServicePackMinor;  

public Int16  wSuiteMask;  

public Byte  wProductType;  

public Byte  wReserved;

}





public class GetSysApi

{

   [ DllImport( "Kernel32.dll" )]

   public static extern bool GetVersionEx( [In, Out] OSVersionInfo osvi );

}



private void button2_Click(object sender, System.EventArgs e)

{

   OSVersionInfo osvi = new OSVersionInfo();

   osvi.OSVersionInfoSize = Marshal.SizeOf( osvi );

  GetSysApi.GetVersionEx(osvi);

  string tm = osvi.buildNumber+osvi.majorVersion+osvi.minorVersion+

      osvi.platformId +osvi.versionString+osvi.wProductType+

      osvi.wReserved+osvi.wSuiteMask;

   MessageBox.Show(tm);//依据那些成员变量,有足够的信息够你对操作系统进行推断

  //我这里仅仅写了你需求的关于windows xp professional或者windows xp home的推断

  if ( osvi.wProductType == 1)

  {

    if( osvi.majorVersion == 4 )

     MessageBox.Show( "Workstation 4.0 ");

    else if(( osvi.wSuiteMask & 512 )!=0) 

      MessageBox.Show("Win Xp Home Edition " );

    else MessageBox.Show("Win Xp Professional " );

   }



}
