Commenti

Questo metodo confronta value con la sottostringa alla fine di questa istanza è uguale alla lunghezza valuee restituisce un valore che indica se sono uguali.This method compares value to the substring at the end of this instance that is the same length as value, and returns an indication whether they are equal. Per essere uguali, value deve essere un riferimento alla stessa istanza o corrisponde alla fine di questa istanza.To be equal, value must be a reference to this same instance or match the end of this instance.

Questo metodo esegue un confronto di word (maiuscole/minuscole e distinzione delle impostazioni cultura) usando le impostazioni cultura correnti.This method performs a word (case-sensitive and culture-sensitive) comparison using the current culture.

Note per i chiamanti

Come illustrato in Best Practices for Using Strings, è consigliabile evitare di chiamare i metodi di confronto tra stringhe che sostituiscono i valori predefiniti e invece chiamano metodi che richiedono parametri per specificare in modo esplicito.As explained in Best Practices for Using Strings, we recommend that you avoid calling string comparison methods that substitute default values and instead call methods that require parameters to be explicitly specified. Per determinare se una stringa termina con una particolare sottostringa tramite le regole di confronto delle impostazioni cultura correnti, chiamare il EndsWith(String, StringComparison) overload del metodo con un valore di CurrentCulture per la relativa comparisonType parametro.To determine whether a string ends with a particular substring by using the string comparison rules of the current culture, call the EndsWith(String, StringComparison) method overload with a value of CurrentCulture for its comparisonType parameter.

Il EndsWith metodo confronta la value parametro con la sottostringa alla fine di questa stringa e restituisce un valore che indica se sono uguali.The EndsWith method compares the value parameter to the substring at the end of this string and returns a value that indicates whether they are equal. Per essere uguali, value deve essere un riferimento a questa stessa stringa, deve essere una stringa vuota (""), oppure deve corrispondere alla fine di questa stringa.To be equal, value must be a reference to this same string, must be the empty string (""), or must match the end of this string. Il tipo di confronto eseguito dal EndsWith metodo dipende dal valore della comparisonType parametro.The type of comparison performed by the EndsWith method depends on the value of the comparisonType parameter.

Determina se la fine di questa istanza di stringa corrisponde alla stringa specificata se confrontata mediante le impostazioni cultura specificate.Determines whether the end of this string instance matches the specified string when compared using the specified culture.

public:
 bool EndsWith(System::String ^ value, bool ignoreCase, System::Globalization::CultureInfo ^ culture);
public bool EndsWith (string value, bool ignoreCase, System.Globalization.CultureInfo culture);
member this.EndsWith : string * bool * System.Globalization.CultureInfo -> bool
Public Function EndsWith (value As String, ignoreCase As Boolean, culture As CultureInfo) As Boolean

Parametri

value
String String String String

Stringa da confrontare con la sottostringa alla fine di questa istanza.The string to compare to the substring at the end of this instance.

ignoreCase
Boolean Boolean Boolean Boolean

true per ignorare la distinzione tra maiuscole e minuscole durante il confronto; in caso contrario, false.to ignore case during the comparison; otherwise, false.

culture
CultureInfo CultureInfo CultureInfo CultureInfo

Informazioni relative alle impostazioni cultura che determinano le modalità di confronto fra questa istanza e il parametro value.Cultural information that determines how this instance and value are compared. Se culture è null, verranno usate le impostazioni cultura correnti.If culture is null, the current culture is used.

Restituisce

true se il parametro value corrisponde alla fine di questa stringa; in caso contrario, false.if the value parameter matches the end of this string; otherwise, false.

Esempi

Nell'esempio seguente determina se una stringa si verifica alla fine di un'altra stringa.The following example determines whether a string occurs at the end of another string. Il EndsWith metodo viene chiamato più volte con distinzione maiuscole/minuscole e maiuscole/minuscole diverse impostazioni cultura che determinano i risultati della ricerca.The EndsWith method is called several times using case sensitivity, case insensitivity, and different cultures that influence the results of the search.

Commenti

Questo metodo confronta la value parametro per la sottostringa alla fine di questa stringa che rappresenta la stessa lunghezza valuee restituisce un valore che indica se sono uguali.This method compares the value parameter to the substring at the end of this string that is the same length as value, and returns a value that indicates whether they are equal. Per essere uguali, value deve essere un riferimento alla stessa istanza oppure corrispondere alla fine di questa stringa.To be equal, value must be a reference to this same instance or match the end of this string.

Questo metodo esegue un confronto (dipendenti dalle impostazioni cultura) di word usando le maiuscole e minuscole specificata e le impostazioni cultura.This method performs a word (culture-sensitive) comparison using the specified casing and culture.
