Collections

Config.Net supports collections for primitive types and interfaces.

Collection must be always declared as IEnumerable<T> and only have a getter.

At the moment collections are read-only and writing to collections may be supported at some point in future releases.

Primitive Types

Suppose you want to read an array of integers, this can be declared as:

interface IMyConfig
{
   IEnumerable<int> Numbers { get; }
}

Interfaces

Reading an array of primitive types is not that interesting as you can always implement parsing yourself by storing some kind of a delimiter in a string i.e. 1,2,3,4 etc. Config.Net allows you to read a collection of your own complex types like so:

interface ICredentials
{
   string Username { get; }
   string Password { get; }
}

interface IMyConfig
{
   IEnumerable<ICredentials> AllCredentials { get; }
}

Limitations

At the moment this feature is relatively new and not every store supports it. In fact only JSON store supports collections.
