Ejemplos

En el ejemplo de código siguiente se muestra una cadena original, las cadenas que genera el ToString método para las claves de ordenación que distinguen mayúsculas de minúsculas y sin distinción entre mayúsculas y minúsculas, y los datos de clave para claves de ordenación que distinguen mayúsculas de minúsculas y sin distinción entre mayúsculas y minúsculas.

    string useCase    = "Use case   ";

// Get a CompareInfo object for the English-Great Britain culture.

// Get a sort key that ignores case for the specified string.

// Get a sort key with no compare option for the specified string.

// Display the original string.

// Display the string equivalent of the two sort keys.

Comentarios

El valor devuelto es la concatenación de la cadena "SortKey - ", el identificador de referencia cultural y las opciones de comparación del objeto actual SortKey y el valor de la OriginalString propiedad .

Este método invalida Object.ToString.
