Si `value` es positivo y `toBase` es 2, 8 o 16, la cadena devuelta usa la representación de signo y magnitud.If `value` is positive and `toBase` is 2, 8, or 16, the returned string uses sign-and-magnitude representation. Si `value` es negativo y `toBase` es 2, 8 o 16, la cadena devuelta utiliza la representación del complemento de dos.If `value` is negative and `toBase` is 2, 8, or 16, the returned string uses two's complement representation. Esto significa que el bit de orden superior del byte de orden superior (bit 15) se interpreta como el bit de signo.This means that the high-order bit of the high-order byte (bit 15) is interpreted as the sign bit.

En el ejemplo siguiente se define NumberFormatInfo una clase personalizada que define su signo negativo como la cadena "~" y su signo positivo como la cadena "!".The following example defines a custom NumberFormatInfo class that defines its negative sign as the string "~" and its positive sign as the string "!". A continuación, llama ToString(Int32, IFormatProvider) al método para convertir cada elemento de una matriz de enteros en su representación de cadena equivalente.It then calls the ToString(Int32, IFormatProvider) method to convert each element in an array of integers to its equivalent string representation. La conversión usa la referencia cultural de todos los idiomas y el NumberFormatInfo objeto personalizado.The conversion uses the invariant culture as well as the custom NumberFormatInfo object.

Si `value` es positivo y `toBase` es 2, 8 o 16, la cadena devuelta usa la representación de signo y magnitud.If `value` is positive and `toBase` is 2, 8, or 16, the returned string uses sign-and-magnitude representation. Si `value` es negativo y `toBase` es 2, 8 o 16, la cadena devuelta utiliza la representación del complemento de dos.If `value` is negative and `toBase` is 2, 8, or 16, the returned string uses two's complement representation. Esto significa que el bit de orden superior del byte de orden superior (bit 31) se interpreta como el bit de signo.This means that the high-order bit of the highest-order byte (bit 31) is interpreted as the sign bit.

### Comentarios

Si el `value` parámetro implementa la IConvertible interfaz, el método llama a la IConvertible.ToString(IFormatProvider) implementación de `value`.If the `value` parameter implements the IConvertible interface, the method calls the IConvertible.ToString(IFormatProvider) implementation of `value`. De lo contrario, `value` si el parámetro implementa IFormattable la interfaz, el método llama IFormattable.ToString(String, IFormatProvider) a su implementación.Otherwise, if the `value` parameter implements the IFormattable interface, the method calls its IFormattable.ToString(String, IFormatProvider) implementation. Si `value` no implementa ninguna interfaz, el método `value` llama al método del `ToString()` parámetro y se omite `provider` el parámetro.If `value` implements neither interface, the method calls the `value` parameter's `ToString()` method, and the `provider` parameter is ignored.

El `provider` parámetro se usa si el `value` parámetro implementa la IConvertible interfaz o IFormattable .The `provider` parameter is used if the `value` parameter implements the IConvertible or IFormattable interface. El uso más común del `provider` parámetro consiste en especificar la información específica de la referencia cultural que se usa en la conversión de. `value`The most common use of the `provider` parameter is to specify culture-specific information used in the conversion of `value`. Por ejemplo, si el `value` parámetro es un número decimal negativo, el `provider` parámetro puede proporcionar información específica de la referencia cultural sobre la notación utilizada para el signo negativo y el separador decimal.For example, if the `value` parameter is a negative decimal number, the `provider` parameter can supply culture-specific information about the notation used for the negative sign and decimal separator. En el segundo ejemplo de la sección siguiente se muestra un proveedor de formato que no proporciona información de formato dependiente de la referencia cultural.The second example in the next section illustrates a format provider that does not supply culture-sensitive formatting information.

## ToString(Single, IFormatProvider)ToString(Single, IFormatProvider)ToString(Single, IFormatProvider)ToString(Single, IFormatProvider)

### Comentarios

Si `toBase` no es igual a 10, la cadena devuelta por el Convert.ToString(Byte, Int32) método solo `value` representa según su magnitud.If `toBase` does not equal 10, the string that is returned by the Convert.ToString(Byte, Int32) method represents `value` by its magnitude only. Si se llama al método para crear una cadena que se convertirá más adelante en un número, se debe llamar a un método correspondiente que asuma una representación numérica de solo magnitud para realizar la conversión.If the method is called to create a string that will later be converted back to a number, a corresponding method that assumes a magnitude-only numeric representation should be called to perform the conversion. Estos métodos incluyen Convert.ToByte(String, Int32) o Byte.Parse(String, NumberStyles).Such methods include Convert.ToByte(String, Int32) or Byte.Parse(String, NumberStyles).

## ToString(String)ToString(String)ToString(String)ToString(String)

Devuelve la instancia de la cadena especificada; no se efectúa una conversión real.Returns the specified string instance; no actual conversion is performed.

``````public:
static System::String ^ ToString(System::String ^ value);``````
``public static string ToString (string value);``
``static member ToString : string -> string``
``Public Shared Function ToString (value As String) As String``

#### Parámetros

value
String String String String

Cadena que se va a devolver.The string to return.

#### Devoluciones

`value` se devuelve sin cambios.`value` is returned unchanged.

### Ejemplos

En el ejemplo siguiente se pasa una cadena ToString(String) al método y se Object.ReferenceEquals llama al método para confirmar que el método devuelve la cadena original.The following example passes a string to the ToString(String) method and calls the Object.ReferenceEquals method to confirm that the method returns the original string. En el ejemplo también se String.IsInterned llama al método para asegurarse de que las dos cadenas no son idénticas, ya que se trata de la cadena original.The example also calls the String.IsInterned method to ensure that the two strings are not identical because the original string is interned.

``````using System;

public class Example
{
public static void Main()
{
String article = "An";
String noun = "apple";
String str1 = String.Format("{0} {1}", article, noun);
String str2 = Convert.ToString(str1);
