When I try to convert a string to float:
Console.WriteLine(float.Parse("6.59"));
it throws an exception:
Unhandled Exception: System.FormatException: Input string was not in a correct f ormat.
at System.Number.ParseSingle(String value, NumberStyles options, NumberFormat Info numfmt)
When I try it like this:
Console.WriteLine(Convert.ToSingle("6.59"));
It throws the same exception:
Unhandled Exception: System.FormatException: Input string was not in a correct f ormat.
at System.Number.ParseSingle(String value, NumberStyles options, NumberFormat Info numfmt)
at System.Convert.ToSingle(String value)
Can you explain why this happens?

A FormatException exception can be thrown for one of the following reasons: In a call to a method that converts a string to some other data type, the string doesn't conform to the required pattern. This typically occurs when calling some methods of the Convert class and the Parse and ParseExact methods of some types.
To correct the error, either remove the format string or substitute a valid one. The following example corrects the error by replacing the invalid format string with the "C" (currency) format string. using System; public class Example { public static void Main() { decimal price = 169.32m; Console.
The single argument Parse method uses the current culture to parse the string. If your current culture uses some other decimal separator, this will fail.
Try using the invariant culture:
float.Parse("6.59", CultureInfo.InvariantCulture)
