Initialize runtime value-type array with specific value?

Question

Is there a way I can initialize the following runtime array to all trues without looping over it using a foreach?

Here is the declaration:

bool[] foo = new bool[someVariable.Count];

Thanks!

Answer 1

bool[] foo = Enumerable.Repeat(true, someVariable.Count)
                       .ToArray();

Answer 2

bool[] bools = (new bool[someVariable.Count]).Select(x => !x).ToArray();

Sort of kidding. Kind of. Almost.
