Dynamically / Programatically get IIS Version

you can get the IIS Version programically by using following way. If you are using Windows 2003 or Windows Vista then you can get by using

DirectoryEntry dirRoot = new DirectoryEntry(IISRoot);
DirectoryEntry child = dirRoot.Children.Find("Info", "IIsWebInfo");
foreach (PropertyValueCollection c in child.Properties)
{
if (string.Compare(c.PropertyName, "MajorIIsVersionNumber", StringComparison.CurrentCultureIgnoreCase) == 0)
{
return Convert.ToInt16(c.Value, CultureInfo.InvariantCulture);
}
}

But if you are using windows XP then It is difficult to get it as it store in a binary. So I tried following way to get the IIS Version and in my case it works fine.

try
{
FileVersionInfo fvi = FileVersionInfo.GetVersionInfo(Environment.SystemDirectory + @"\inetsrv\inetinfo.exe");
Console.WriteLine("Version:" + fvi.FileVersion +"\nMajor Part: " + fvi.FileMajorPart + "." + fvi.FileMinorPart);
}
catch (FileNotFoundException ex)
{
throw ex;
}
