Comentarios

De forma predeterminada, la comparación se realiza CompareOptions.Nonemediante.By default, the comparison is performed by using CompareOptions.None. Si una decisión de seguridad depende de una comparación de cadenas o de un cambio de mayúsculas InvariantCulture y minúsculas, debe usar la propiedad para asegurarse de que el comportamiento sea coherente independientemente de la configuración de la referencia cultural del sistema operativo.If a security decision depends on a string comparison or a case change, you should use the InvariantCulture property to ensure that the behavior is consistent regardless of the culture settings of the operating system.

Nota

Cuando sea posible, debe llamar a métodos de comparación de cadenas que tengan un CompareOptions parámetro de tipo para especificar el tipo de comparación esperada.When possible, you should call string comparison methods that have a parameter of type CompareOptions to specify the kind of comparison expected. Como norma general, use las opciones lingüísticas (con la referencia cultural actual) para comparar las cadenas que se muestran en la Ordinal interfaz OrdinalIgnoreCase de usuario y especifique o para las comparaciones de seguridad.As a general rule, use linguistic options (using the current culture) for comparing strings displayed in the user interface and specify Ordinal or OrdinalIgnoreCase for security comparisons.

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.Character sets include ignorable characters, which are characters that are not considered when performing a linguistic or culture-sensitive comparison. El Compare(String, String) método no tiene en cuenta estos caracteres cuando realiza una comparación dependiente de la referencia cultural.The Compare(String, String) method does not consider such characters when it performs a culture-sensitive comparison. Por ejemplo, una comparación dependiente de la referencia cultural de "animal" con "Ani-malintencionado" (con un guion blando o U + 00AD) indica que las dos cadenas son equivalentes, como se muestra en el ejemplo siguiente.For instance, a culture-sensitive comparison of "animal" with "ani-mal" (using a soft hyphen, or U+00AD) indicates that the two strings are equivalent, as the following example shows.

[!code-vbSystem.Globalization.CompareInfo.Compare#1][!code-vbSystem.Globalization.CompareInfo.Compare#1]

Para reconocer los caracteres que se van a pasar por alto en Compare(String, String, CompareOptions) una comparación de cadenas, llame al Ordinal método y proporcione options un valor de o OrdinalIgnoreCase para el parámetro.To recognize ignorable characters in a string comparison, call the Compare(String, String, CompareOptions) method and supply a value of either Ordinal or OrdinalIgnoreCase for the options parameter.

Si una decisión de seguridad depende de una comparación de cadenas o de un cambio de mayúsculas InvariantCulture y minúsculas, debe usar la propiedad para asegurarse de que el comportamiento sea coherente independientemente de la configuración de la referencia cultural del sistema operativo.If a security decision depends on a string comparison or a case change, you should use the InvariantCulture property to ensure that the behavior is consistent regardless of the culture settings of the operating system.

Nota

Cuando sea posible, debe llamar a métodos de comparación de cadenas que tengan un CompareOptions parámetro de tipo para especificar el tipo de comparación esperada.When possible, you should call string comparison methods that have a parameter of type CompareOptions to specify the kind of comparison expected. Como norma general, use las opciones lingüísticas (con la referencia cultural actual) para comparar las cadenas que se muestran en la Ordinal interfaz OrdinalIgnoreCase de usuario y especifique o para las comparaciones de seguridad.As a general rule, use linguistic options (using the current culture) for comparing strings displayed in the user interface and specify Ordinal or OrdinalIgnoreCase for security comparisons.

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.Character sets include ignorable characters, which are characters that are not considered when performing a linguistic or culture-sensitive comparison. El Compare(String, String, CompareOptions) método no tiene en cuenta estos caracteres cuando realiza una comparación dependiente de la referencia cultural.The Compare(String, String, CompareOptions) method does not consider such characters when it performs a culture-sensitive comparison. Para reconocer los caracteres que se van a pasar por alto en la Ordinal comparación OrdinalIgnoreCase , proporcione options un valor de o para el parámetro.To recognize ignorable characters in your comparison, supply a value of Ordinal or OrdinalIgnoreCase for the options parameter.

Si una decisión de seguridad depende de una comparación de cadenas o de un cambio de mayúsculas InvariantCulture y minúsculas, debe usar la propiedad para asegurarse de que el comportamiento sea coherente independientemente de la configuración de la referencia cultural del sistema operativo.If a security decision depends on a string comparison or a case change, you should use the InvariantCulture property to ensure that the behavior is consistent regardless of the culture settings of the operating system.

Nota

Cuando sea posible, debe llamar a métodos de comparación de cadenas que tengan un CompareOptions parámetro de tipo para especificar el tipo de comparación esperada.When possible, you should call string comparison methods that have a parameter of type CompareOptions to specify the kind of comparison expected. Como norma general, use las opciones lingüísticas (con la referencia cultural actual) para comparar las cadenas que se muestran en la Ordinal interfaz OrdinalIgnoreCase de usuario y especifique o para las comparaciones de seguridad.As a general rule, use linguistic options (using the current culture) for comparing strings displayed in the user interface and specify Ordinal or OrdinalIgnoreCase for security comparisons.

El Compare(String, Int32, String, Int32, CompareOptions) método no tiene en cuenta estos caracteres al realizar una comparación dependiente de la referencia cultural.The Compare(String, Int32, String, Int32, CompareOptions) method does not consider such characters when performing a culture-sensitive comparison.
