Convert dictionary values into array


Question

What is the most efficient way of turning the list of values of a dictionary into an array?

For example, if I have a Dictionary where Key is String and Value is Foo, I want to get Foo[]

I am using VS 2005, C# 2.0

Accepted Answer

// dict is Dictionary<string, Foo>

Foo[] foos = new Foo[dict.Count];
dict.Values.CopyTo(foos, 0);

// or in C# 3.0:
var foos = dict.Values.ToArray();

Store it in a list. It is easier;

List<Foo> arr = new List<Foo>(dict.Values);

Of course if you specifically want it in an array;

Foo[] arr = (new List<Foo>(dict.Values)).ToArray();
