The appropriate way to do this would be:
LINQ stands for Language Integrated Query. It is for performing queries on data. Queries do not mutate the underlying structures. Since what you want to do is to mutate one of the queries LINQ is not an appropriate tool.
Also note that
Removereturns a boolean indicating whether or not it actually removed the key. It doesn’t throw an exception. You don’t need to callContainsKeybefore calling remove (this will save you an extra table lookup for each item).
