Question

I’d like to be able to extend ConfigurationManager so that I have an app.config some like the following:

<configuration>

<databases>
    <add name="db1" server="someServer" dbName="superDB" userName="" password=""/>
    <add name="db2" server="anotherServer" dbName="ordinaryDB" userName="dba" password="dba"/>
</databases>

</configuration>

And then to be able to access these fields via ConfigurationManager like so

string dbName = ConfigurationManager.Databases["db1"].DBName;

I’ve had a look at customization options available (here for instance) but it doesn’t really give me what I’m trying to achieve. Is this even possible?

(I realise that I could do this by rolling my own configuration manager but I’d really prefer to extend what the .NET framework currently offers if at all possible)

Answer 1

It looks like you should use the ConfigurationManager.ConnectionStrings property in this case.

If you really do want to extend the App.Config to contain your own configuration section(s) you can create a class that derives from ConfigurationSection class. There is a good example here.

What you expressed in your question… to be able to do something like ConfigurationManager.Databases, where Databases is a custom static property on ConfigurationManager class, is not possible.
