Key value pairs in C# Params

Question

I\'m looking for a way to have a function such as:

myFunction({\"Key\", value}, {\"Key2\", value});

I\'m sure there\'s something with anonymous

A bit of a hack, but you could have your Message class implement the IEnumerable interface and give it an Add method. You'll then be able to use collection initializer syntax:

Agent.SendMessage
(
    new Message(MessageTypes.SomethingHappened) {{ "foo", 42 }, { "bar", 123 }}
);

// ...

public class Message : IEnumerable
{
    private Dictionary _map = new Dictionary();

    public Message(MessageTypes mt)
    {
        // ...
    }

    public void Add(string key, object value)
    {
        _map.Add(key, value);
    }

    IEnumerator IEnumerable.GetEnumerator()
    {
        return ((IEnumerable)_map).GetEnumerator();
        // or throw a NotImplementedException if you prefer
    }
}
