C# Associative Arrays

To perform key/value pair style associative "arrays" in C# that you may be familiar with from e.g. PHP you can use the Dictionary class to create a nongeneric collection of key/value pairs.

Sample code with iteration example:

private Dictionary<string, int> OutgoingConnections = new Dictionary<string, int>();
	
OutgoingConnections.Add("foo") = 1;
OutgoingConnections.Add("bar") = 2;

foreach (KeyValuePair<string, int> c in OutgoingConnections) {
	// Do something with c.Key/c.Value.
}

You can declare with IDictionary if expected as an argument for something, but I recommend instantiating the new object itself Dictionary class.
