GenericEnumConverter Class
Assembly: System.Configuration (in system.configuration.dll)
This type, like all the other configuration converter types, converts strings found in the configuration file to and from the related strongly typed properties.
In particular, the GenericEnumConverter object converts a String value, assigned to a configuration property, to an Enum value and vice versa.
The following code example shows how to access a custom section property that uses the GenericEnumConverter type.
using System; using System.IO; using System.ComponentModel; using System.Configuration; namespace Samples.AspNet { public sealed class UsingGenericEnumConverter { public static void GetPermission() { try { CustomSection section = ConfigurationManager.GetSection("CustomSection") as CustomSection; Console.WriteLine("Default Permission: {0", section.Permission.ToString()); catch (System.Exception e) { Console.WriteLine(e.Message); public static void SetPermission() { try { System.Configuration.Configuration config = ConfigurationManager.OpenExeConfiguration( ConfigurationUserLevel.None); CustomSection section = config.Sections.Get("CustomSection") as CustomSection; section.Permission = CustomSection.Permissions.FullControl; section.SectionInformation.ForceSave = true; config.Save(ConfigurationSaveMode.Full); config.Save(); Console.WriteLine("Current Protection: {0", section.Permission.ToString()); catch (System.Exception e) { Console.WriteLine(e.Message);
The following code example shows how to define a custom enumerator property accessed in the previous example. Notice that there is no need to specify the GenericEnumConverter type; it is implicitly invoked by the system.
public enum Permissions { FullControl = 0, Modify = 1, ReadExecute = 2, Read = 3, Write = 4, SpecialPermissions = 5 [ConfigurationProperty("permission", DefaultValue = Permissions.Read)] public Permissions Permission { get { return (Permissions)this["permission"]; set { this["permission"] = value;
The following is a configuration excerpt used by the previous example.
