Splitting CamelCase

Question

This is all asp.net c#.

I have an enum

public enum ControlSelectionType 
{
    NotApplicable = 1,
    SingleSelectRadioButtons = 2,
    SingleSelectD

Tillito's answer does not handle strings already containing spaces well, or Acronyms. This fixes it:

public static string SplitCamelCase(string input)
{
    return Regex.Replace(input, "(?<=[a-z])([A-Z])", " $1", RegexOptions.Compiled);
}
