LINQ query to return a Dictionary

Question

I have a collection of MyClass that I\'d like to query using LINQ to get distinct values, and get back a Dictionary as the result, but I can\'t figure out

Answer 1

Use the ToDictionary method directly.

var result = 
  // as Jon Skeet pointed out, OrderBy is useless here, I just leave it 
  // show how to use OrderBy in a LINQ query
  myClassCollection.OrderBy(mc => mc.SomePropToSortOn)
                   .ToDictionary(mc => mc.KeyProp.ToString(), 
                                 mc => mc.ValueProp.ToString(), 
                                 StringComparer.OrdinalIgnoreCase);

Answer 2

Look at the ToLookup and/or ToDictionary extension methods.
