Dictionary of Arrays to Single Array

Question

Simple question that I can't seem to find an answer to:

In C#, how do you take a Dictionary< TKey, TValue[] > and make it an TValue[] array - get all values from the dictionary into a single array?

I've tried experimenting with LINQ but can't find a solution, probably easier than I think.

You can use SelectMany from LINQ:

 var array = dic.SelectMany(p => p.Value).ToArray();

Thanks. That worked! I haven't used SelectMany, just Select LINQ.

if it is Dictionary, should that just be dic.Values.ToArray()?

@EthanLi: the result of your code will be TValue[][], not TValue[]
