did you try float.Parse()?

This not "convert" (this word is a real curse of CodeProject inquirers, I don't know why), this is "parse":
http://msdn.microsoft.com/en-us/library/fd84bdyt.aspx[^],
http://msdn.microsoft.com/en-us/library/7yd1h1be.aspx[^],
http://msdn.microsoft.com/en-us/library/t9ebt447.aspx[^],
http://msdn.microsoft.com/en-us/library/0kb11ck8.aspx[^],
http://msdn.microsoft.com/en-us/library/994c0zb1.aspx[^],
http://msdn.microsoft.com/en-us/library/3s27fasw.aspx[^].

And yes, for most applications you really want to use double, not Single. For System.Single (alias float), all methods are the same:
http://msdn.microsoft.com/en-us/library/system.single.aspx[^].

The difference the "Try…" forms of methods make is that they do not throw exceptions, ever. (They do not throw and then catch as I thought, they don't throw at all; I checked up this implementation detail by source code.) Instead, you check up the return values to see if the parsing is successful or not.
