How do I replace multiple spaces with a single space in C#?

Question

How can I replace multiple spaces in a string with only one space in C#?

Example:

1 2 3  4    5

would be:

1 2 3 4 5

Without using regular expressions:

while (myString.IndexOf("  ", StringComparison.CurrentCulture) != -1)
{
    myString = myString.Replace("  ", " ");
}

OK to use on short strings, but will perform badly on long strings with lots of spaces.
