이 인스턴스를 지정된 개체와 비교하고 상대 값의 표시를 반환합니다.

public:
 virtual int CompareTo(System::Object ^ target);
public int CompareTo(object target);
public int CompareTo(object? target);
abstract member CompareTo : obj -> int
override this.CompareTo : obj -> int
Public Function CompareTo (target As Object) As Integer

매개 변수

target
Object

비교할 개체 또는 null.

반품

Int32

이 인스턴스의 상대 값을 나타내는 부호 있는 숫자입니다 target.

값 의미
0보다 작음 이 인스턴스의 값이 .의 target값보다 작습니다.
0 이 인스턴스의 값은 의 값 target과 같습니다.
0보다 큼 이 인스턴스의 값이 값보다 target크거나 target 입니다 null.

구현

CompareTo(Object)

예외

ArgumentException

target 이 인스턴스는 동일한 형식이 아닙니다.

InvalidOperationException

이 인스턴스는 형식SByte, ,Int16Int32, Int64, Byte, UInt16UInt32또는 UInt64.

NullReferenceException

이 인스턴스는 null입니다.

예제

다음 예제에서는 컨텍스트에서의 CompareTo 사용을 보여 줍니다 Enum.

using System;

public class CompareToTest {
    enum VehicleDoors { Motorbike = 0, Sportscar = 2, Sedan = 4, Hatchback = 5 };

        VehicleDoors yourVeh = VehicleDoors.Motorbike;
        VehicleDoors otherVeh = VehicleDoors.Sedan;

        Console.WriteLine("Does a {0} have more doors than a {1}?", myVeh, yourVeh);
        Console.WriteLine( "{0}{1}", myVeh.CompareTo(yourVeh) > 0 ? "Yes" : "No", Environment.NewLine );

        Console.WriteLine("Does a {0} have more doors than a {1}?", myVeh, otherVeh);
        Console.WriteLine( "{0}", myVeh.CompareTo(otherVeh) > 0 ? "Yes" : "No" );
    }
}
// The example displays the following output:
