Int32.Parse () VS Convert.ToInt32 ()?
IntID1 = Int32.Parse (MyValue.toString()); intID2 = Convertir.ToInt32 (MyValue);
¿Cuál es mejor y por qué?

Son exactamente iguales, excepto que Convert.ToInt32(null)
devuelve 0
.
Convert.ToInt32
se define como sigue:
public static int ToInt32(String value) {
if (value == null)
return 0;
return Int32.Parse(value, CultureInfo.CurrentCulture);
}

Bueno, el Reflector dice...
public static int ToInt32(string value)
{
if (value == null)
{
return 0;
}
return int.Parse(value, CultureInfo.CurrentCulture);
}
public static int Parse(string s)
{
return Number.ParseInt32(s, NumberStyles.Integer, NumberFormatInfo.CurrentInfo);
}
Así que son básicamente lo mismo excepto que Convert.ToInt32()
hace una comprobación null añadida.
