Remarks

The default implementation of this method will allocate a string and call Convert(String, CultureInfo, CommandLineArgument). Override this method if a direct conversion from a ReadOnlySpanT is possible for the target type.

Exceptions

ArgumentNullException	culture or argument is .
FormatException	The value was not in a correct format for the target type.
OverflowException	The value was out of range for the target type.
CommandLineArgumentException	The value was not in a correct format for the target type. Unlike FormatException and OverflowException, a CommandLineArgumentException thrown by this method will be passed down to the user unmodified.
