Comentarios

De forma predeterminada, la comparación se realiza mediante CompareOptions.None. Si una decisión de seguridad depende de una comparación de cadenas o un cambio de caso, debe usar la InvariantCulture propiedad para asegurarse de que el comportamiento sea coherente independientemente de la configuración de referencia cultural del sistema operativo.

Nota

Cuando sea posible, debe llamar a métodos de comparación de cadenas que tengan un parámetro de tipo CompareOptions para especificar el tipo de comparación esperado. Como regla general, use opciones lingüísticas (mediante la referencia cultural actual) para comparar cadenas mostradas en la interfaz de usuario y especificar Ordinal o OrdinalIgnoreCase para comparaciones de seguridad.

Notas a los autores de las llamadas

Los juegos de caracteres incluyen caracteres que se pueden pasar por alto, que son los caracteres que no se tienen en cuenta al realizar una comparación lingüística o en la que se tiene en cuenta la referencia cultural. El Compare(String, String) método no tiene en cuenta estos caracteres cuando realiza una comparación que distingue la referencia cultural. Por ejemplo, una comparación que distingue la referencia cultural de "animal" con "ani-mal" (mediante un guión suave o U+00AD) indica que las dos cadenas son equivalentes, como se muestra en el ejemplo siguiente.

Imports System.Globalization

Module Example
   Public Sub Main()
      Dim ci As CompareInfo = CultureInfo.CurrentCulture.CompareInfo
      Dim s1 As String = "ani" + ChrW(&h00AD) + "mal"
      Dim s2 As String = "animal"
      
      Console.WriteLine("Comparison of '{0}' and '{1}': {2}", 
                        s1, s2, ci.Compare(s1, s2))
  End Sub
End Module
' The example displays the following output:
'       Comparison of 'ani-mal' and 'animal': 0

Para reconocer caracteres ignorables en una comparación de cadenas, llame al Compare(String, String, CompareOptions) método y proporcione un valor de Ordinal o OrdinalIgnoreCase para el options parámetro .

Comentarios

Si una decisión de seguridad depende de una comparación de cadenas o un cambio de caso, debe usar la InvariantCulture propiedad para asegurarse de que el comportamiento sea coherente independientemente de la configuración de referencia cultural del sistema operativo.

Nota

Notas a los autores de las llamadas

Los juegos de caracteres incluyen caracteres que se pueden pasar por alto, que son los caracteres que no se tienen en cuenta al realizar una comparación lingüística o en la que se tiene en cuenta la referencia cultural. El Compare(String, String, CompareOptions) método no tiene en cuenta estos caracteres cuando realiza una comparación que distingue la referencia cultural. Para reconocer caracteres ignorables en la comparación, proporcione un valor de Ordinal o OrdinalIgnoreCase para el options parámetro .

Comentarios

Nota

Cuando sea posible, debe usar métodos de comparación de cadenas que tengan un parámetro de tipo CompareOptions para especificar el tipo de comparación esperado. Como regla general, use opciones lingüísticas (mediante la referencia cultural actual) para comparar cadenas mostradas en la interfaz de usuario y especificar Ordinal o OrdinalIgnoreCase para comparaciones de seguridad.

Notas a los autores de las llamadas

Los juegos de caracteres incluyen caracteres que se pueden pasar por alto. El Compare(String, Int32, Int32, String, Int32, Int32) método no tiene en cuenta estos caracteres cuando realiza una comparación lingüística o sensible a la referencia cultural. Para reconocer caracteres ignorables en la comparación, llame al Compare(String, Int32, Int32, String, Int32, Int32, CompareOptions) método y proporcione un valor de Ordinal o OrdinalIgnoreCase para el options parámetro .
