App.config格式和.NET中的访问数据

Question

I'm new with editing app.config. I'd like to have this section in app.config:

<name1>
    <name2>
        <name3 att="something1">value1</name3>
        <name3 att="something2">value2</name3>
        ...
    </name2>
</name1>

How to create it and access it from code? I want to get something1 , something2 , value1 and value2 . I found this tutorial , but it shows only how to get something1 , not something2 , value1 and value2 (Approach Four in tutorial).

Thank you for any help.

Answer 1

You'll need a custom configuration collection by subclassing ConfigurationElementCollection .

Assuming <name1> is a immediate child of the root element you'll need:

• A custom section for <name1>
• It will need a custom collection for <name2>
• A custom element (to be a member of the collection) for each <name3> .

Answer 2

I solved it. First I needed to edit ConfigurationElement class for <name3> , I used the sample in this post . Then I needed to create class from ConfigurationElementCollection - so simpy coppied code for UrlsCollection class from the link and overwrited there all UrlConfigElement to my ConfigurationElement class.

var section = ConfigurationManager.GetSection("name1") as Name1ConfigurationElement;
var collection = section.Name2;
foreach (SqlElement element in collection)
{
    Console.WriteLine(element.Value);
}
