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;

}

当然，大家直接可以通过 OperatingSystem os = Environment.OSVersion;然后判断os.Version.Major是否是等于6，就可以判断系统是不是windows Vista以上版本
