    How to know which IIS versions are installed from a WinForm in C#?

    Reply Contact

    Hello,

     I was looking all over the Internet to find an answer I'm sure there must be an easy way to get the IIS versions running on the Server.

    My old methods aren't working anymore on Windows 7 and Windows Server 2008:
    Old broken Method:

    DirectoryEntry entry = null; eWebServerVersions iisVersion = eWebServerVersions.Unknown;

    try

    {

    entry =     new DirectoryEntry("IIS://LOCALHOST/W3SVC/INFO");

    }

    catch

    {

    trace.Log(    EnumTraceLevel.methods, "IISAppPool.cs", "GetIISServerVersion", "UNKNOWN VERSION");

    }

    int ver = 5;

    try

    {

    ver = (    int)entry.Properties["MajorIISVersionNumber"].Value;

    }

     

    I hope there is a nice clean way multiplatform ...

    Something like

    ServerManager iisManager = new ServerManager();

    iisManager.Version !!!!!


    Or do I have to check which platform I'm on and then assume the IIS version from it?

    Like it says here: http://stackoverflow.com/questions/446390/how-to-detect-iis-version-using-c

    I would just check the version of the OS: xp has IIS 5.1, Server 2003 has IIS 6 and vista/Server 2008 has IIS 7.

    Here's how to check the version of the OS.

     Thanks a lot for your help

    The most elegant way to retrieve the IIS version on XP as well as Windows 7 so far is:

    FileVersionInfo verinfo = FileVersionInfo.GetVersionInfo(System.Environment.SystemDirectory + @"\inetsrv\inetinfo.exe");

    string version =  verinfo.FileMajorPart;

    IIS major and minor version is available under the following registry key as well. HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\InetStp

    I found reading in the registry a little bit cumbersome, would you have the C# code to it quickly?

    Thx ;)

    Here is a quick way you can get a Version out of it:

    Note that I typed it in notepad so it could have errors, but the idea should work :)

    Version GetIisVersion() {
      using (RegistryKey componentsKey =
        Registry.LocalMachine.OpenSubKey(@"Software\Microsoft\INETSTP\Components", false)) {

        if (componentsKey != null) {
            int majorVersion = (int)componentsKey.GetValue("MajorVersion", -1);
            int minorVersion = (int)componentsKey.GetValue("MinorVersion", -1);
            if (majorVersion != -1 && minorVersion != -1) {
                return new Version(majorVersion, minorVersion);
            }
        }
        return new Version(0, 0);
    }

    Great! thanks for that, my previous solution wasn't working on Windows 2008 so I'll use the registry method instead.

    CarlosAg>I changed the registry path to where I can read the IIS version to this:

    public Version GetIisVersionMS()
    {
    using (RegistryKey     componentsKey =
    Registry.LocalMachine.OpenSubKey(@"Software\Microsoft\InetStp", false    ))
    {
    if (componentsKey != null    )
    {
    int majorVersion = (int)componentsKey.GetValue("MajorVersion"    , -1);
    int minorVersion = (int)componentsKey.GetValue("MinorVersion"    , -1);
    if     (majorVersion != -1 && minorVersion != -1)
    {
    return new Version    (majorVersion, minorVersion);
    }
    }
    return new Version    (0, 0);
    }
    }

    Tested on Windows 7, Windows 2008 and XP :)
