How to read a personal section in a web.config ?

<MyPersonalSection>
    <add name="toto" enable="true" URL="http://localhost:43242" />
    <add name="titi" enable="false" URL="http://localhost:98762" />
<MyPersonalSection/>

I'd like to get the enable value and/or URL value with the name value.

I also have this mistake : Unrecognized configuration section MyPersonalSection

I been trying

var config = ConfigurationManager.GetSection("MyPersonalSection");

You don't need to write a custom configuration handler to get what you want. There are built-in configuration handlers that you can use if you simply want key-value entries. But, you'll have to use key instead of name and value instead of URL . For example:

<configuration>
 <configSections>
  <section name="MyPersonalSection" type="System.Configuration.NameValueSectionHandler" />
 </configSections>
<MyPersonalSection>
    <add key="toto" value="http://localhost:43242" />
    <add key="titi" value="http://localhost:98762" />
</MyPersonalSection>
</configuration>

And you can access them via code:

var myValues = ConfigurationSettings.GetConfig("MyPersonalSection") as NameValueCollection;
var url = myValues["toto"];

I would suggest naming your keys in a way that makes it clear what the value should be, like "totoUrl" and "titiUrl".

If you want something other than string value pairs, you'll have to write your own custom handler.

You can add appSettings section in your web.config with key that you will need. For example:

<configuration>
   <appSettings>
      <add key="FirstUrl" value="http://localhost:43242"/>
      <add key="SecondUrl" value="http://localhost:98762" />
    </appSettings>
 ...
</configuration>

So, since aspx.cs file, you can declare directive

using System.Configuration;

And later, you can retrieve FirstUrl value in this way:

 var myUrl = ConfigurationManager.AppSettings["FirstUrl"];
