Take a look at https://wiki.gnome.org/Projects/Vala/GeeSamples#Map_Example
Also type inference may be your friend here and save you a bit of typing.

So 


Gee.HashMap<string, string> foo = new Gee.HashMap<string, string>();

would be

var foo = new Gee.HashMap<string, string>();


and


foreach(Gee.Map.Entry<string, string> bar in foo){}
would be


foreach(var bar in foo.entries){}


Hope that helps,
