fromStringOrThrow

public static unsigned short fromStringOrThrow(string numberAsStr)

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

Parameters

numberAsStr

The string value to convert.

Converts a string to a valid unsigned short 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 unsigned short 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 {
    unsigned short x = UInteger16.fromStringOrThrow("100");
}
catch(InvalidNumberException e) {
    // Will not execute because the string value is numeric
    Console.error(e);
}

try {
    unsigned short y = UInteger16.fromStringOrThrow("abc");
}
catch(InvalidNumberException e) {
    Console.error(e);
}

If the string being converted is numeric but does not fit into the unsigned short data range [ 0, 65535 ] (inclusive), System.Exceptions.IntegerOutOfRangeException will be thrown.

import System;
import System.Exceptions;

try {
    unsigned short exceedByOne = UInteger16.fromStringOrThrow("65536");
}
catch(IntegerOutOfRangeException e) {
    Console.error(e);
}
