SortKey.Compare(SortKey, SortKey) 메서드

정의

네임스페이스:

System.Globalization

어셈블리:

System.Runtime.dll

Source:

SortKey.cs

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

매개 변수

sortkey1

SortKey

비교할 첫째 정렬 키입니다.

sortkey2

SortKey

비교할 둘째 정렬 키입니다.

반환

Int32

sortkey1과(와) sortkey2 간의 관계를 나타내는 부호 있는 정수입니다.

값	조건
0보다 작음	sortkey1가 sortkey2보다 작은 경우
0	sortkey1이(가) sortkey2와 같은 경우.
0보다 큼	sortkey1가 sortkey2보다 큰 경우

예외

ArgumentNullException

sortkey1 또는 sortkey2가 null인 경우

예제

다음 코드 예제에서는 메서드와 동등한 CompareInfo.Compare(String, String, CompareOptions) 메서드를 Compare 사용하는 두 문자열을 비교합니다.

// This code example demonstrates the CompareInfo.Compare() and
