Best way to parse a string to a float with both "," and "." as fraction separator? (For a number < 5)

Question

This is kind of related to my previous question, but not really. I have an input of which I don't know the culture. So it can both use ',' and '.' as separator for the fraction. The number will never be >5 though, so we can be rather sure if there's a separator, it will be for the fraction.

I was looking at the TryParse method. It accepts a NumberStyles argument. But I don't see anything about fraction separator or the like..

Am I missing something again or is there a better way to reach my goal?

Try this:

float.TryParse(myString.Replace(',', '.'), out myfloat);

EDIT: as Jon mentioned, the following way is recommended:

float.TryParse(myString.Replace(',', '.'), 
               System.Globalization.NumberStyles.Float, 
               System.Globalization.NumberFormatInfo.InvariantInfo, 
               out myFloat);
