Uwagi

Domyślnie porównanie jest wykonywane przy użyciu CompareOptions.None.By default, the comparison is performed by using CompareOptions.None. Jeśli decyzja dotycząca zabezpieczeń zależy od porównania ciągów lub zmiany wielkości liter, należy użyć InvariantCulture właściwości, aby upewnić się, że zachowanie jest spójne niezależnie od ustawień kultury systemu operacyjnego.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.

Uwaga

Jeśli to możliwe, należy wywołać metody porównywania ciągów, które mają parametr typu CompareOptions , aby określić oczekiwany rodzaj porównania.When possible, you should call string comparison methods that have a parameter of type CompareOptions to specify the kind of comparison expected. Ogólną zasadą jest użycie opcji językowych (przy użyciu bieżącej kultury) do porównywania ciągów wyświetlanych w interfejsie użytkownika Ordinal i OrdinalIgnoreCase określania lub do porównania zabezpieczeń.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.

Uwagi dotyczące wywoływania

Zestawy znaków zawierają znaki do pominięcia. Są to znaki nieuwzględniane podczas porównywania pod względem językowym lub z uwzględnieniem ustawień kulturowych.Character sets include ignorable characters, which are characters that are not considered when performing a linguistic or culture-sensitive comparison. Compare(String, String) Metoda nie uwzględnia takich znaków, gdy wykonuje porównanie z uwzględnieniem kultury.The Compare(String, String) method does not consider such characters when it performs a culture-sensitive comparison. Na przykład porównanie wrażliwe na kulturę "zwierzę" z "lub" niezłośliwe "(przy użyciu łącznika miękkiego lub U + 00AD) wskazuje, że dwa ciągi są równoważne, jak pokazano w poniższym przykładzie.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]

Aby rozpoznać ignorowanie znaków w porównaniu ciągów, wywołaj Compare(String, String, CompareOptions) metodę i podaj wartość albo Ordinal lub OrdinalIgnoreCase dla options parametru.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.

Compare(String, String, CompareOptions) Compare(String, String, CompareOptions) Compare(String, String, CompareOptions) Compare(String, String, CompareOptions)

Uwagi

Jeśli decyzja dotycząca zabezpieczeń zależy od porównania ciągów lub zmiany wielkości liter, należy użyć InvariantCulture właściwości, aby upewnić się, że zachowanie jest spójne niezależnie od ustawień kultury systemu operacyjnego.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.

Uwaga

Jeśli to możliwe, należy wywołać metody porównywania ciągów, które mają parametr typu CompareOptions , aby określić oczekiwany rodzaj porównania.When possible, you should call string comparison methods that have a parameter of type CompareOptions to specify the kind of comparison expected. Ogólną zasadą jest użycie opcji językowych (przy użyciu bieżącej kultury) do porównywania ciągów wyświetlanych w interfejsie użytkownika Ordinal i OrdinalIgnoreCase określania lub do porównania zabezpieczeń.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.
