Get distinct items from a list

Question

I have a list of objects with three integer properties. How can I get the distinct values of first integer property from my list?

Answer 1

This should work,

List<int> result = YourListObject.Select(o => o.FirstInteger).Distinct().ToList();

Answer 2

Try:

var g = collection.Select(i => i.Property1).Distinct();

Could you post some source code so that we can give you a better example?

EDIT:

In my example, I have a collection collection which contains numerous instances of your class. I'm then selecting Property1 from each class, filtering to the distinct values of that property.
