두 정렬 키를 비교합니다.
public:
static int Compare(System::Globalization::SortKey ^ sortkey1, System::Globalization::SortKey ^ sortkey2);
public static int Compare (System.Globalization.SortKey sortkey1, System.Globalization.SortKey sortkey2);
static member Compare : System.Globalization.SortKey * System.Globalization.SortKey -> int
Public Shared Function Compare (sortkey1 As SortKey, sortkey2 As SortKey) As Integer
- sortkey1
- SortKey
비교할 첫째 정렬 키입니다.
- sortkey2
- SortKey
비교할 둘째 정렬 키입니다.
sortkey1
과(와) sortkey2
간의 관계를 나타내는 부호 있는 정수입니다.
값 | 조건 |
---|---|
0보다 작음 | sortkey1 가 sortkey2 보다 작은 경우
|
0 | sortkey1 이(가) sortkey2 와 같은 경우.
|
0보다 큼 | sortkey1 가 sortkey2 보다 큰 경우
|
sortkey1
또는 sortkey2
가 null
인 경우
다음 코드 예제에서는 메서드와 동등한 CompareInfo.Compare(String, String, CompareOptions) 메서드를 Compare 사용하는 두 문자열을 비교합니다.
