Convert dictionary values into array
// 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();
There is a ToArray() function on Values:
Foo[] arr = new Foo[dict.Count];
dict.Values.CopyTo(arr, 0);
But I don't think its efficient (I haven't really tried, but I guess it copies all these values to the array). Do you really need an Array? If not, I would try to pass IEnumerable:
IEnumerable<Foo> foos = dict.Values;
If you would like to use linq, so you can try following:
Dictionary<string, object> dict = new Dictionary<string, object>();
var arr = dict.Select(z => z.Value).ToArray();
I don't know which one is faster or better. Both work for me.
