直接提供Winform程序：
OperatingSystem os = Environment.OSVersion;
switch (os.Platform)
{
case PlatformID.Win32Windows:
switch (os.Version.Minor)
{
case 0:
label1.Text = "Windows 95 ";
break;
case 10:
if (os.Version.Revision.ToString() == "2222A ")
label1.Text = "Windows 98 第二版 ";
else
label1.Text = "Windows 98 ";
break;
case 90:
label1.Text = "Windows Me ";
break;
}
break;
case PlatformID.Win32NT:
switch (os.Version.Major)
{
case 3:
label1.Text = "Windows NT 3.51 ";
break;
case 4:
label1.Text = "Windows NT 4.0 ";
break;
case 5:
switch (os.Version.Minor)
{
case 0:
label1.Text = "Windows 200 ";
break;
case 1:
label1.Text = "Windows XP ";
break;
case 2:
label1.Text = "Windows 2003 ";
break;
}
break;
case 6:
switch (os.Version.Minor)
{
case 0:
label1.Text = "Windows Vista ";
break;
case 1:
label1.Text = "Windows 7 ";
break;
}
break;
}
break;
}
當然，大家直接可以通過 OperatingSystem os = Environment.OSVersion;然後判斷os.Version.Major是否是等於6，就可以判斷系統是不是windows Vista以上版本
