Comentarios

El uso del ToUInt16(String) método equivale a pasar value al UInt16.Parse(String) método . value se interpreta mediante las convenciones de formato de la referencia cultural actual.

Si prefiere no controlar una excepción si se produce un error en la conversión, puede llamar al UInt16.TryParse método en su lugar. Devuelve un Boolean valor que indica si la conversión se realizó correctamente o no.

Si fromBase es 16, puede prefijar el número especificado por el value parámetro con "0x" o "0X".

Dado que el UInt16 tipo de datos solo admite valores sin firmar, el ToUInt16(String, Int32) método supone que value se expresa mediante una representación binaria sin signo. En otras palabras, todos los 16 bits se usan para representar el valor numérico y un bit de signo no está presente. Como resultado, es posible escribir código en el que un valor entero con signo que está fuera del intervalo del tipo de UInt16 datos se convierte en un UInt16 valor sin que el método produzca una excepción. En el ejemplo siguiente se convierte Int16.MinValue en su representación de cadena hexadecimal y, a continuación, se llama al ToUInt16(String, Int32) método . En lugar de iniciar una excepción, el método muestra el mensaje "0x8000 convierte en 32768".

// Create a hexadecimal value out of range of the UInt16 type.
string value = Convert.ToString(Int16.MinValue, 16);
// Convert it back to a number.

Al realizar operaciones binarias o conversiones numéricas, siempre es responsabilidad del desarrollador comprobar que un método o operador usa la representación numérica adecuada para interpretar un valor determinado. En el ejemplo siguiente se muestra una técnica para asegurarse de que el método no usa inapropiadamente la representación binaria para interpretar un valor que usa la representación complementaria de dos al convertir una cadena hexadecimal en un UInt16 valor. En el ejemplo se determina si un valor representa un entero con signo o sin signo mientras convierte ese valor en su representación de cadena. Cuando el ejemplo convierte el valor en un UInt16 valor, comprueba si el valor original era un entero con signo. Si es así, y si se establece su bit de orden alto (lo que indica que el valor original era negativo), el método produce una excepción.

Comentarios

El valor devuelto es el resultado de invocar el IConvertible.ToUInt16 método del tipo subyacente de value.

provider permite al usuario especificar información de conversión específica de la referencia cultural sobre el contenido de value. Por ejemplo, si value es un String objeto que representa un número, provider podría proporcionar información específica de la referencia cultural sobre la notación utilizada para representar ese número.

Los tipos base omiten provider; sin embargo, el parámetro se puede usar si value es un tipo definido por el usuario que implementa la IConvertible interfaz.

Ejemplos

En el ejemplo siguiente se convierte cada elemento de una matriz de Double valores en un entero de 16 bits sin signo.

double[] numbers = { Double.MinValue, -1.38e10, -1023.299, -12.98,
                    0, 9.113e-16, 103.919, 17834.191, Double.MaxValue };
ushort result;

foreach (double number in numbers)
{
   try {
      result = Convert.ToUInt16(number);
      Console.WriteLine("Converted the {0} value '{1}' to the {2} value {3}.",
                        number.GetType().Name, number,
                        result.GetType().Name, result);
   }
   catch (OverflowException)
   {
      Console.WriteLine("{0} is outside the range of the UInt16 type.", number);
   }
}
// The example displays the following output:
//    -1.79769313486232E+308 is outside the range of the UInt16 type.
