예제

다음 예제에서는 "en-US" 및 "es-ES" 문화권을 사용하여 문자열 "llama"와 "en-US" 및 "es-ES" 전통 문화권을 비교합니다.

다음 예제에서는 클래스를 SortKey 사용하여 큰 배열을 정렬하고 검색하는 데 광범위하게 의존하는 애플리케이션의 성능을 향상시키는 방법을 보여 줍니다. 이 예제에서는 순서가 지정되지 않은 이름 배열을 만듭니다. 이 경우 13개의 요소가 있습니다. 그런 다음 각 이름의 정렬 키를 메서드에 전달하는 병렬 배열에 Sort(Array, Array) 저장합니다. 결과는 정렬된 배열입니다. 그런 다음, 배열에서 세 개의 문자열을 검색합니다. 각 검색 문자열에 GetSortKey(String, CompareOptions) 대해 메서드를 호출하여 문자열의 정렬 키를 검색한 다음, 정렬 키 배열에서 해당 정렬 키의 인덱스 검색을 위해 메서드를 호출 Array.FindIndex 합니다. 이름 및 정렬 키 배열은 병렬이므로 반환된 인덱스는 배열에 있는 names 이름의 인덱스이기도 합니다.
