fromStringOrThrow

public static byte fromStringOrThrow(string numberAsStr)

The byte equivalent of the string value if the string is a valid byte value and does not overflow (the string value fits within the byte data range).

Parameters

numberAsStr

The string value to convert.

Converts a string to a valid byte value or throws an exception if the value cannot be converted. If the string value is not numeric, System.Exceptions.InvalidNumberException will be thrown. If the string value is outside the range of valid values for the byte data type, System.Exceptions.IntegerOutOfRangeException is thrown.

For string values that are not numeric, System.Exceptions.InvalidNumberException is thrown:

import System;
import System.Exceptions;

try {
    byte x = UInteger8.fromStringOrThrow("100");
}
catch(InvalidNumberException e) {
    // Will not execute because the string value is numeric
    Console.error(e);
}

try {
    byte y = UInteger8.fromStringOrThrow("abc");
}
catch(InvalidNumberException e) {
    Console.error(e);
}

If the string being converted is numeric but does not fit into the byte data range [ 0, 255 ] (inclusive), System.Exceptions.IntegerOutOfRangeException will be thrown.

import System;
import System.Exceptions;

try {
    byte exceedByOne = UInteger8.fromStringOrThrow("256");
}
catch(IntegerOutOfRangeException e) {
    Console.error(e);
}
