How to add values to Named Array of Class Type?

Question

I have a Array Configuration[] wrapped with ConfigurationArray class, how I can add values to array using ConfigurationArray.

public class ConfigurationArray
{
    [DataMember(Name = "configurations")]
    public Configuration[] Configurations { get; set; }
}

public class Configuration
{        
    [DataMember(Name = "configurationType")]
    public string ConfigurationType { get; set; }

    [DataMember(Name = "configurationValue")]
    public string ConfigurationValue { get; set; }
}

Having a ConfigurationArray class in which itself exposes a Configuration array feels a little weird to me. Instead of wrapping the array, I'd simply expose a List<Configuration> via whoever needs such a list. — Yuval Itzchakov

Agree with @YuvalItzchakov or you could inherent from Collection<Configuration> if you need to provide additional functionality for the collection but i'd still recommend changing the class name. — DGibbs

You can't. An array has a fixed size, so the only thing you can do in order to add one to the array, is to 'expand the array' by creating a new one with a bigger size than the previous one and copy all items over.

The best option you have is to use a List<Configuration> instead of Configuration[], which is capable of sizing itself.
