How do I detect non-printable characters in .NET?

Question

I'm just wondering if there is a method in .NET 2.0 that checks whether a character is printable or not – something like isprint(int) from standard C.

I found Char.IsControl(Char).

Could that be used for this purpose?

Answer 1

private bool IsPrintableCharacter(char candidate)
{
    return !(candidate < 0x20 || candidate > 127);
}

Answer 2

Or as an extension method.

public static bool IsPrintable(this char candidate){
    return !(candidate < 0x20 || candidate > 127);
}
