Devuelve una nueva cadena cuya representación binaria tiene una forma de normalización Unicode determinada.
Sobrecargas
Normalize() |
Devuelve una nueva cadena cuyo valor textual es igual que esta cadena, pero cuya representación binaria tiene la forma de normalización Unicode C. |
Normalize(NormalizationForm) |
Devuelve una nueva cadena cuyo valor textual es igual que esta cadena, pero cuya representación binaria tiene la forma de normalización Unicode especificada. |
Ejemplos
En el ejemplo siguiente se normaliza una cadena en cada uno de los cuatro formularios de normalización, se confirma que la cadena se normalizó en el formulario de normalización especificado y, a continuación, enumera los puntos de código de la cadena normalizada.

Devuelve una nueva cadena cuyo valor textual es igual que esta cadena, pero cuya representación binaria tiene la forma de normalización Unicode C.
public:
System::String ^ Normalize();
public string Normalize ();
member this.Normalize : unit -> string
Public Function Normalize () As String
Devoluciones
Una nueva cadena normalizada cuyo valor textual es igual que esta cadena, pero cuya representación binaria tiene la forma de normalización C.
Excepciones
La instancia actual contiene caracteres Unicode no válidos.
Comentarios
Algunos caracteres Unicode tienen varias representaciones binarias equivalentes que constan de conjuntos de caracteres Unicode combinados o compuestos. Por ejemplo, cualquiera de los siguientes puntos de código puede representar la letra "ắ":
U+1EAF
U+0103 U+0301
U+0061 U+0306 U+0301
La existencia de varias representaciones para un solo carácter complica la búsqueda, la ordenación, la coincidencia y otras operaciones.
El estándar Unicode define un proceso denominado normalización que devuelve una representación binaria cuando se da cualquiera de las representaciones binarias equivalentes de un carácter. La normalización se puede realizar con varios algoritmos, denominados formularios de normalización, que cumplen diferentes reglas. .NET admite los cuatro formularios de normalización (C, D, KC y KD) definidos por el estándar Unicode. Cuando dos cadenas se representan en el mismo formulario de normalización, se pueden comparar mediante la comparación ordinal.
Para normalizar y comparar dos cadenas, haga lo siguiente:
Obtenga las cadenas que se van a comparar desde un origen de entrada, como un archivo o un dispositivo de entrada de usuario.
Llame al Normalize() método para normalizar las cadenas al formulario de normalización C.
Para comparar dos cadenas, llame a un método que admita la comparación de cadenas ordinales, como el Compare(String, String, StringComparison) método y proporcione un valor de StringComparison.Ordinal o StringComparison.OrdinalIgnoreCase como argumento StringComparison . Para ordenar una matriz de cadenas normalizadas, pase un
comparer
valor de StringComparer.Ordinal o StringComparer.OrdinalIgnoreCase a una sobrecarga adecuada de Array.Sort.Emita las cadenas en la salida ordenada según el orden indicado por el paso anterior.
Para obtener una descripción de los formularios de normalización Unicode admitidos, consulte System.Text.NormalizationForm.
Notas a los autores de las llamadas
El IsNormalized método devuelve false
tan pronto como encuentra el primer carácter no normalizado en una cadena. Por lo tanto, si una cadena contiene caracteres no normalizados seguidos de caracteres Unicode no válidos, el Normalize método producirá un ArgumentException aunque IsNormalized devuelve false
.
