# DateTime.Compare(DateTime, DateTime) 메서드

## 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

비교할 첫 번째 개체입니다.The first object to compare.

t2
DateTime

비교할 두 번째 개체입니다.The second object to compare.

#### 반환

Int32

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

값 형식Value Type 조건Condition
0보다 작습니다.Less than zero `t1``t2`보다 이전인 경우`t1` is earlier than `t2`.
0Zero `t1``t2`와 같은 경우`t1` is the same as `t2`.
0보다 큽니다.Greater than zero `t1``t2`보다 나중인 경우`t1` is later than `t2`.

## 예제

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

``````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 for en-us culture:
//    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

`t2``t1` 관계를 확인 하기 위해 Compare 메서드는 `t1``t2`Ticks 속성을 비교 하지만 Kind 속성은 무시 합니다.To determine the relationship of `t1` to `t2`, the Compare method compares the Ticks property of `t1` and `t2` but ignores their Kind property. DateTime 개체를 비교 하기 전에 개체가 동일한 표준 시간대의 시간을 표시 하는지 확인 합니다.Before comparing DateTime objects, ensure that the objects represent times in the same time zone.
