DateTime.Compare(DateTime, DateTime) DateTime.Compare(DateTime, DateTime) DateTime.Compare(DateTime, DateTime) DateTime.Compare(DateTime, DateTime) Method

정의

DateTime의 두 인스턴스를 비교하고 첫 번째 인스턴스가 두 번째 인스턴스보다 빠른지, 같은지, 늦은지를 나타내는 정수를 반환합니다.Compares two instances of DateTime and returns an integer that indicates whether the first instance is earlier than, the same as, or later than the second instance.

public:
 static int Compare(DateTime t1, DateTime t2);
public static int Compare (DateTime t1, DateTime t2);
static member Compare : DateTime * DateTime -> int
Public Shared Function Compare (t1 As DateTime, t2 As DateTime) As Integer

매개 변수

t1
DateTime DateTime DateTime DateTime

비교할 첫 번째 개체입니다.The first object to compare.

t2
DateTime DateTime DateTime DateTime

비교할 두 번째 개체입니다.The second object to compare.

반환

t1t2의 상대 값을 나타내는 부호 있는 숫자입니다.A signed number indicating the relative values of t1 and t2.

값 형식Value Type 조건Condition
0보다 작음Less than zero t1t2보다 이전인 경우t1 is earlier than t2.
0Zero t1t2와 같은 경우t1 is the same as t2.
0보다 큼Greater than zero t1t2보다 나중인 경우t1 is later than t2.

예제

다음 예제는 Compare 메서드.The following example demonstrates the Compare method.

using System;

public class Example
{
   public static void Main()
   {
      DateTime date1 = new DateTime(2009, 8, 1, 0, 0, 0);
      DateTime date2 = new DateTime(2009, 8, 1, 12, 0, 0);
      int result = DateTime.Compare(date1, date2);
      string relationship;
      
      if (result < 0)
         relationship = "is earlier than";
      else if (result == 0)
         relationship = "is the same time as";         
      else
         relationship = "is later than";

      Console.WriteLine("{0} {1} {2}", date1, relationship, date2);
   }
}
// The example displays the following output:
//    8/1/2009 12:00:00 AM is earlier than 8/1/2009 12:00:00 PM
Module Example
   Public Sub Main()
      Dim date1 As Date = #08/01/2009 12:00AM#
      Dim date2 As Date = #08/01/2009 12:00PM#
      Dim result As Integer = DateTime.Compare(date1, date2)
      Dim relationship As String
      
      If result < 0 Then
         relationship = "is earlier than"
      ElseIf result = 0 Then
         relationship = "is the same time as"         
      Else
         relationship = "is later than"
      End If
      
      Console.WriteLine("{0} {1} {2}", date1, relationship, date2)
   End Sub
End Module
' The example displays the following output:
'    8/1/2009 12:00:00 AM is earlier than 8/1/2009 12:00:00 PM

설명

관계를 확인 하려면 t1t2, Compare 메서드 비교를 Ticks 속성을 t1t2 무시 하지만 해당 Kind 속성.To determine the relationship of t1 to t2, the Compare method compares the Ticks property of t1 and t2 but ignores their Kind property. 비교 하기 전에 DateTime 개체를 개체 동일한 표준 시간대의 시간을 나타내는 것을 확인 합니다.Before comparing DateTime objects, ensure that the objects represent times in the same time zone.
