Custom Config section in App.config C#
c#, configuration, custom-configuration
Solution
App.config:
<?xml version="1.0" encoding="utf-8" ?>
<configuration>
<configSections>
<sectionGroup name="customAppSettingsGroup">
<section name="customAppSettings" type="System.Configuration.AppSettingsSection, System.Configuration, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a" />
</sectionGroup>
</configSections>
<customAppSettingsGroup>
<customAppSettings>
<add key="KeyOne" value="ValueOne"/>
<add key="KeyTwo" value="ValueTwo"/>
</customAppSettings>
</customAppSettingsGroup>
</configuration>
Usage:
NameValueCollection settings =
ConfigurationManager.GetSection("customAppSettingsGroup/customAppSettings")
as System.Collections.Specialized.NameValueCollection;
if (settings != null)
{
foreach (string key in settings.AllKeys)
{
Response.Write(key + ": " + settings[key] + "<br />");
}
}
Problem
I'm a quite beginner with config sections in c# I want to create a custom section in config file. What I've tried after googling is as the follows Config file: ``` <?xml version="1.0" encoding="utf-8" ?> <configuration> <configSections> <sectionGroup name="MyCustomSections"> <section name="CustomSection" type="CustomSectionTest.CustomSection,CustomSection"/> </sectionGroup> </configSections> <MyCustomSections> <CustomSection key="Default"/> </MyCustomSections> </configuration> ``` CustomSection.cs ``` namespace CustomSectionTest { public class CustomSection : ConfigurationSection { [ConfigurationProperty("key", DefaultValue="Default", IsRequired = true)] [StringValidator(InvalidCharacters = "~!@#$%^&*()[]{}/;'\"|\\", MinLength = 1, MaxLength = 60)] public String Key { get { return this["key"].ToString(); } set { this["key"] = value; } } } } ``` When I use this code to retrieve Section I get an error saying configuration error. ``` var cf = (CustomSection)System.Configuration.ConfigurationManager.GetSection("CustomSection"); ``` What am I missing? Thanks. Edit What I need ultimately is ``` <CustomConfigSettings> <Setting id="1"> <add key="Name" value="N"/> <add key="Type" value="D"/> </Setting> <Setting id="2"> <add key="Name" value="O"/> <add key="Type" value="E"/> </Setting> <Setting id="3"> <add key="Name" value="P"/> <add key="Type" value="F"/> </Setting> </CustomConfigSettings> ```
