\nWenn man ein Programm mit Vb.net erstellt, ist es in den meisten F\u00e4llen nicht notwendig, die Windows Version abzufragen, auf welchen das Programm ausgef\u00fchrt wird. Doch programmiert man ein Tool\/Programm was auf spezielle Funktionen zur\u00fcckgreift, die nur in von einer bestimmten Windows Version unterst\u00fctzt werden, so ist es ganz praktisch beim Programmstart die Version in Erfahrung zu bringen.
\nDa .net hier sehr viele Funktionen bietet um Systeminformationen abzufragen, ist dies mit einer kleinen Funktion sehr schnell erledigt.
\n\u00dcber den System Zugriff: System.Environment.OSVersion erh\u00e4lt man als R\u00fcckgabewert eine Nummer. Entsprechende Unterabfragen wie platform, major und minor liefern weitere Zahlen, mit welchen sich durch Kombination das Betriebssystem ermitteln l\u00e4sst.
\nIn der MSDN Online Bibliothek kann man nachlesen welche Nummer\/Kombination welchen Betriebssystem entspricht.<\/p>\n\n\n\n\n\n\n
<\/td>\nWindows 98<\/td>\nWindows Me<\/td>\nWindows NT 4.0<\/td>\nWindows 2000<\/td>\nWindows XP<\/td>\nWindows Server 2003<\/td>\nWindows Vista \/2008 Server<\/td>\nWindows 7<\/td>\n<\/tr>\n
Platform<\/td>\n1<\/td>\n1<\/td>\n2<\/td>\n2<\/td>\n2<\/td>\n2<\/td>\n2<\/td>\n2<\/td>\n<\/tr>\n
Version.Major<\/td>\n4<\/td>\n4<\/td>\n4<\/td>\n5<\/td>\n5<\/td>\n5<\/td>\n6<\/td>\n6<\/td>\n<\/tr>\n

In der Funktion lassen sich \u00fcber Select Case Anweisungen das Betriebssystem „filtern“.<\/p>\n

R\u00fcckgabe der Version
\nDie komplette Funktion sieht wie folgt aus:<\/p>\n
