 How do I ensure that my list contains all unique items in Linq?
I have a List<T> in my class. I want to make sure that it contains unique items.
Everything that has a computer in will fail. Everything in your life, from a watch to a car to, you know, a radio, to an iPhone, it will fail if it has a computer in it. They should kill the people who made those things.- 'Woz'

For the query itself, use the ".Distinct()" clause.
Other than that, use a HashSet (.NET 3.5 or higher) or a Dictionary instead for unique values.

I am not querying the list, though I suppose, I could do that too. I went with a HashSet object.
