namespace AdministrationSnippets
    public class AdministrationSectionDefinition
        // List all configuration sections in applicationHost.config
        public void ShowAllSections()
            ServerManager manager = new ServerManager();
            SectionGroup rootGroup = 
            ShowGroup(rootGroup, -1);


        private void ShowGroup(SectionGroup group, int indentLevel)
            Console.Write("".PadLeft(++indentLevel, ' '));
            string grpName = String.IsNullOrEmpty(group.Name) ? "{root}" : group.Name;
            Console.WriteLine("+ Section Group: {0}; Sub-groups: {1}; Sections: {2}",
                grpName, group.SectionGroups.Count, group.Sections.Count);

            foreach (SectionGroup grp in group.SectionGroups)
                ShowGroup(grp, indentLevel);

            string path = String.Concat(group.Name, "/");

            foreach (SectionDefinition def in group.Sections)
                Console.Write("".PadLeft(indentLevel, ' '));
                Console.WriteLine("|_Name:                {0}", String.Concat(path,def.Name));
                Console.Write("".PadLeft(indentLevel, ' '));
                Console.WriteLine("|_AllowDefinition:     {0}", def.AllowDefinition);
                Console.Write("".PadLeft(indentLevel, ' '));
                Console.WriteLine("|_AllowLocation:       {0}", def.AllowLocation);
                Console.Write("".PadLeft(indentLevel, ' '));
                Console.WriteLine("|_OverrideModeDefault: {0}", def.OverrideModeDefault);
                Console.Write("".PadLeft(indentLevel, ' '));
                Console.WriteLine("|_Type:                {0}\r\n", 
                    String.IsNullOrEmpty(def.Type) ? "null" : def.Type);



Declaring a configuration section defines a new element for the configuration file. The new element contains settings that a configuration section handler reads. The attributes and child elements of a section you define depend on the section handler you use to read your settings.

The following <configuration> element contains an example of the <section> element that the SectionDefinition class represents.



<section name="sampleSection"




<sampleSection setting1="Value1" setting2="value two"

setting3="third value" />

Name Name Name Name

Gets the name of the current configuration section definition.

OverrideModeDefault OverrideModeDefault OverrideModeDefault OverrideModeDefault
