.net - C# Array initialization - with non-default value

Question

What is the slickest way to initialize an array of dynamic size in C# that you know of?

This is the best I could come up with

private bool[] GetPageNumbersToLink(IPagedResult result)
{
   if (result.TotalPages <= 9)
      return new bool[result.TotalPages + 1].Select(b => true).ToArray();

   ...

Answer 1

If by 'slickest' you mean fastest, I'm afraid that Enumerable.Repeat may be 20x slower than a for loop. See http://dotnetperls.com/initialize-array:

Initialize with for loop:             85 ms  [much faster]
Initialize with Enumerable.Repeat:  1645 ms 

So use Dotnetguy's SetAllValues() method.
