XP 和 2K的Major 都是5, Minor不同,2k对应0,XP对应1. System.Environment.OSVersion.Version.Major System.Environment.OSVersion.Version.Minor

Version ver = System.Environment.OSVersion.Version;
string strClient = "";
if (ver.Major == 5 && ver.Minor == 1)
{
strClient = "Win XP";
}
else if (ver.Major == 6 && ver.Minor == 0)
{
strClient = "Win Vista";
}
else if (ver.Major == 6 && ver.Minor == 1)
{
strClient = "Win 7";
}
else if (ver.Major == 5 && ver.Minor == 0)
{
strClient = "Win 2000";
}
