.net - Parse string to float number C#

Question

I have float number in string. there is one problem. Number uses "." not "," as decimal point.

This code is not working:

MyNumber = float.Parse("123.5");

I know that I can use string replace function to "repair" this string before Parsing.

MyNumber = float.Parse("123.5".Replace('.',',');

But is there any other way to do it?

Answer 1

Using string replace is very fragile, and will lead to suttle bugs. Specify the IFormatProvider instead. For instance:

MyNumber = float.Parse("123.5", CultureInfo.InvariantCulture);

Or you can specify the NumberFormatInfo using another overload of Parse.
