(1). I would like to validate a string, checking if it has only {a-z], [A-Z], [0-9], '-'}
if(minhaString.ContemApenas({[a-z], [A-Z], [0-9], '-'}) == true)
{
// Minha string é válida!
}
(2). I need to also validate if such a string is a Guid.
if(minhaString == Guid){
// String é um Guid Válido!
}
It's pretty easy to do both, see:
using System;
using System.Text.RegularExpressions;
using static System.Console;
public class Program
{
public static void Main()
{
string str = "palavra1-2-3";
Regex rgx = new Regex(@"^[a-zA-Z0-9-]+$");
bool isValid = rgx.IsMatch(str);
WriteLine(isValid);
//Para verificar se a string é uma Guid
Guid result;
bool isGuid = Guid.TryParse(str, out result);
WriteLine(isGuid);
}
}
I would like to validate a string, checking if it has only {a-z], [A-Z], [0-9], '-'}
It can be done like this:
var re = new Regex("[A-Za-z0-9\-]+");
var valido = re.Match("Minha String 1-2-3").Success;
I also need to validate if that string is a
Guid
The fastest way is this:
var guidValido = PInvoke.ObjBase.CLSIDFromString(meuGuid, out valor) >= 0;
