      <defaultDocument enabled="true">

Sample Code

The following examples enable default documents on a Web site named Contoso then add a file named Home.html to the list of default documents for the site.


appcmd.exe set config "Contoso" /section:defaultDocument /enabled:true /+files.[value='home.html']

            ConfigurationSection defaultDocumentSection = config.GetSection("system.webServer/defaultDocument");
            defaultDocumentSection["enabled"] = true;
            ConfigurationElementCollection filesCollection = defaultDocumentSection.GetCollection("files");
            ConfigurationElement addElement = filesCollection.CreateElement("add");
            addElement["value"] = @"home.html";
            filesCollection.AddAt(0, addElement);
