Question

I get hex values and need to know if my (parameter that is INT) is in the range of the values.
for example:

public bool IsInTheRange(int parameter) {
    string range = "0A-0F";
    return = ????  
}

How can I check if the parameter is in the range of 0A-0F ?

Answer 1

Does the range really need to be specified as a string?

public bool IsInTheRange(int parameter)
{
    int rangeMin = 0x0A;
    int rangeMax = 0x0F;

    return (parameter >= rangeMin) && (parameter <= rangeMax);
}

…and if it does need to be a string then you’ll still need to parse that string into min and max bounds:

public bool IsInTheRange(int parameter)
{
    string range = "0A-0F";
    string rangeArray = range.Split('-')
                             .Select(x => int.Parse(x, NumberStyles.HexNumber))
                             .ToArray();

    return (parameter >= rangeArray[0]) && (parameter <= rangeArray[1]);
}
