How to Add Custom Tag in Web.Config Page (ASP.NET)

To add a custom tag to Web.config you need to first explicitly specify the new tag name in Web.config via the <configSections> tag

For Example:

<configuration>

<configSections>

<section name="MyAppSettings"
type="System.Configuration.NameValueFileSectionHandler,
System, Version=1.0.3300.0, Culture=neutral,
PublicKeyToken=b77a5c561934e089" />

</configSections>
...
</configuration>

This <section ... /> tag indicates that we are going to be adding New tag named MyAppSettings.

Now we can add a <MyAppSettings> tag to our Web.config file and
add <add ... /> tags to add application-wide parameters,

For Example:

<configuration>

<configSections>

<section name="MyAppSettings"
type="System.Configuration.NameValueFileSectionHandler,
System, Version=1.0.3300.0, Culture=neutral,
PublicKeyToken=b77a5c561934e089" />
</configSections>

<MyAppSettings>
<add key="connString" value="connection string" />
</MyAppSettings>
...
</configuration>

How to Read Custom Tag

To read this custom value from an ASP.NET Web page we use the following syntax:

ConfigurationSettings.GetConfig("MyAppSettings")("connString")
