Say I have a dictionary

<br />
Dictionary<int, Dictionary<int, String>><br />

What is the best way to remove an item from the "nested" dictionary?

For e.g.:

Dictionary<int, Dictionary<int, string>> outer = new Dictionary<int, Dictionary<int, string>>();

This Dictionary is then populated with stuff and I want to remove the existing item outer[1][2], I would usually do:

Dictionary<int, string> inner = outer[1];
outer.Remove(1);
inner.Remove(2);
outer.Add(1, inner);

Is there a better/shorter/more straightforward way?
