Creating an IIS Site through managed code

Another task I had in the past along with creating the DNS entries via managed code, was creating a new site in IIS. I had to nip various code from various places, but when I got done, it all worked nicely together. You will notice by the try catch block, that again, I was executing this chunk of code from a web based application. Needless to say, chances are you won’t have the permissions to do this unless you do. This code works on IIS 6.0 with Windows 2003 Server Std Edition . I’d imagine it’s more IIS specific than OS specific, but this is the only version of Windows I’ve tested it with.

public static string CreateWebSite(string NewSiteIP, string webSiteName, string pathToRoot, string DomainName)
    int siteID = 1;
    string sSiteID = “”;

        CreatePhysicalDirectory(pathToRoot, webSiteName);

        ManagementScope _scope = new ManagementScope(@”\\WINDOWS\root\MicrosoftIISV2″, null);

        ManagementObject oW3SVC = new ManagementObject(_scope, new ManagementPath(@”IIsWebService=’W3SVC’”), null);
        DirectoryEntry root = new DirectoryEntry(”IIS://WINDOWS/W3SVC”);

        #region get a good site id
        foreach (DirectoryEntry e in root.Children)
            if (e.SchemaClassName == “IIsWebServer”)
                int ID = Convert.ToInt32(e.Name);
                if (ID >= siteID)
                    siteID = ID + 1;

        ManagementScope mScope = null;
        ManagementPath mPath = new ManagementPath();
        mPath.ClassName = “ServerBinding”;
        mPath.NamespacePath = “root\\MicrosoftIISv2″;
        mScope = new ManagementScope(mPath);
        mScope.Path.Server = “WINDOWS”;

        #region Create the new Site
        ManagementBaseObject[] serverBindings = new ManagementBaseObject[2];
        serverBindings[0] = CreateServerBinding(DomainName, NewSiteIP, “80″);
        serverBindings[1] = CreateServerBinding(”www.” + DomainName, NewSiteIP, “80″);

        ManagementBaseObject inputParameters = oW3SVC.GetMethodParameters(”CreateNewSite”);
        inputParameters["ServerComment"] = ConfigurationManager.AppSettings["SitePrefix"] + webSiteName;
        inputParameters["ServerBindings"] = serverBindings;
        inputParameters["PathOfRootVirtualDir"] = pathToRoot + webSiteName;
        inputParameters["ServerId"] = siteID;

        ManagementBaseObject outParameter = null;
        outParameter = oW3SVC.InvokeMethod(”CreateNewSite”, inputParameters, null);
        // return is like IIsWebServer=’W3SVC/2145288186′

        sSiteID = Convert.ToString(outParameter.Properties["ReturnValue"].Value).Replace(”IIsWebServer=’W3SVC/”,”").Replace(”‘”,”");

        ManagementObject site = new ManagementObject(_scope,
            new ManagementPath(Convert.ToString(outParameter.Properties["ReturnValue"].Value)),

        #region Remap ScriptMaps
        ManagementObjectSearcher searcher = new ManagementObjectSearcher(@”root\MicrosoftIISv2″,
            “SELECT * FROM IIsWebVirtualDirSetting WHERE Path = ‘” + pathToRoot.Replace(@”\”,@”\\”) + webSiteName + “‘”) ;

        foreach(ManagementObject queryObj in searcher.Get())
            if (queryObj.Properties["ScriptMaps"] != null)
                Object[] arrScriptMaps = (Object[])(queryObj["ScriptMaps"]);
                foreach (Object arrValue in arrScriptMaps)
                    foreach (PropertyData data in ((ManagementBaseObject)arrValue).Properties)
                            if (data.Name == “ScriptProcessor”)
                                data.Value = @”c:\windows\\framework\v2.0.50727\aspnet_isapi.dll”;
                queryObj.SetPropertyValue(”ScriptMaps”, arrScriptMaps);

        ManagementPath myPath = new ManagementPath();
        myPath.Path = @”IIsWebVirtualDirSetting.Name=’W3SVC/” + siteID.ToString() + “/root’”;
        ManagementObject oWebVDir = new ManagementObject(_scope, myPath, null);

        oWebVDir.Properties["AppFriendlyName"].Value = “mah new app”;
        oWebVDir.Properties["AccessRead"].Value = true;
        //oWebVDir.Properties["ServerAutoStart"].Value = true;
        oWebVDir.Properties["AuthFlags"].Value = 5; // Integrated Windows Auth.
        oWebVDir.Properties["AccessScript"].Value = true;
        oWebVDir.Properties["AuthAnonymous"].Value = true;
        oWebVDir.Properties["AppPoolId"].Value = “MyAppPoolName”;

        site.InvokeMethod(”Start”, null);
    catch (Exception ex)
        HttpContext.Current.Response.Write(ex.Message + “<BR>”);

    return sSiteID;
