copied!<p>When key value pairs are not enough I use Configuration Sections as they are not complex to use (unless you need a complex section):</p> <p>Define your custom section:</p> <pre><code> public class CustomSection : ConfigurationSection { [ConfigurationProperty("LastName", IsRequired = true, DefaultValue = "TEST")] public String LastName { get { return (String)base["LastName"]; } set { base["LastName"] = value; } } [ConfigurationProperty("FirstName", IsRequired = true, DefaultValue = "TEST")] public String FirstName { get { return (String)base["FirstName"]; } set { base["FirstName"] = value; } } public CustomSection() { } } </code></pre> <p>Programmatically create your section (if it doesn't already exist):</p> <pre><code> // Create a custom section. static void CreateSection() { try { CustomSection customSection; // Get the current configuration file. System.Configuration.Configuration config = ConfigurationManager.OpenExeConfiguration(@"ConfigurationTest.exe"); // Create the section entry // in the <configSections> and the // related target section in <configuration>. if (config.Sections["CustomSection"] == null) { customSection = new CustomSection(); config.Sections.Add("CustomSection", customSection); customSection.SectionInformation.ForceSave = true; config.Save(ConfigurationSaveMode.Full); } } catch (ConfigurationErrorsException err) { //manage exception - give feedback or whatever } } </code></pre> <p>Following CustomSection definition and actual CustomSection will be created for you:</p> <pre><code><?xml version="1.0" encoding="utf-8" ?> <configuration> <configSections> <section name="CustomSection" type="ConfigurationTest.CustomSection, ConfigurationTest, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null" allowLocation="true" allowDefinition="Everywhere" allowExeDefinition="MachineToApplication" overrideModeDefault="Allow" restartOnExternalChanges="true" requirePermission="true" /> </configSections> <CustomSection LastName="TEST" FirstName="TEST" /> </configuration> </code></pre> <p>Now Retrieve your section properties:</p> <pre><code> CustomSection section = (CustomSection)ConfigurationManager.GetSection("CustomSection"); string lastName = section.LastName; string firstName = section.FirstName; </code></pre>
