Poznámky

Tato metoda porovnává value parametr s podřetězcec na konci tohoto řetězce, který má stejnou délku jako valuea vrátí hodnotu, která označuje, zda jsou si rovny. Chcete-li být rovni, value musí být odkaz na stejnou instanci nebo odpovídat konci tohoto řetězce.

Tato metoda provede porovnání slov (s citlivými na jazykovou verzi) pomocí zadaných písmen a jazykové verze.

Poznámky

Metoda EndsWith porovnává value parametr s podřetězcec na konci tohoto řetězce a vrátí hodnotu, která označuje, zda jsou si rovny. Chcete-li být rovni, value musí být odkazem na stejný řetězec, musí být prázdný řetězec (""), nebo musí odpovídat konci tohoto řetězce. Typ porovnání provedený metodou EndsWith závisí na hodnotě parametru comparisonType .

Následující příklad definuje metodu StripEndTags , která používá metodu EndsWith(String) k odebrání koncových značek HTML z konce řádku. Všimněte si StripEndTags , že metoda je volána rekurzivně, aby se zajistilo, že se na konci řádku odebere více koncových značek HTML.

Poznámky

Tato metoda porovnává value s podřetěžcem na konci této instance, který má stejnou délku jako valuea vrátí indikaci, zda jsou si rovny. Aby byla rovna, value musí být odkazem na stejnou instanci nebo odpovídat konci této instance.

Tato metoda provádí porovnání slov (velká a malá písmena a specifika jazykové verze) použitím aktuální jazykové verze.

Poznámky pro volající

Jak je vysvětleno v části Osvědčené postupy pro používání řetězců, doporučujeme vyhnout se volání metod porovnání řetězců, které nahrazují výchozí hodnoty, a místo toho volejte metody, které vyžadují explicitní zadání parametrů. Chcete-li zjistit, zda řetězec končí na konkrétní podřetězce pomocí pravidel porovnání řetězců aktuální jazykové verze, signalizovat váš záměr explicitně voláním EndsWith(String, StringComparison) přetížení metody s hodnotou CurrentCulture pro její comparisonType parametr. Pokud nepotřebujete lingvistické porovnání, zvažte použití Ordinal.
