how does except method work in linq

Question

I have the classes:

class SomeClass
{
   public string Name{get;set;}
   public int SomeInt{get;set;}
}


class SomeComparison: IEqualityComparer

        

Answer 1

This is the way i think about it.

IEnumerable Except(IEnumerable a,IEnumerable b)
{
    return a.Where(x => !b.Contains(x)).Distinct();
}
