Point.Equality(Point, Point) Operator

Definition

Point 구조체가 같은지 여부를 비교합니다.Compares two Point structures for equality.

public:
 static bool operator ==(System::Windows::Point point1, System::Windows::Point point2);
public static bool operator == (System.Windows.Point point1, System.Windows.Point point2);
static member ( = ) : System.Windows.Point * System.Windows.Point -> bool
Public Shared Operator == (point1 As Point, point2 As Point) As Boolean

Parameters

point1
Point

비교할 첫 번째 Point 구조체입니다.The first Point structure to compare.

point2
Point

비교할 두 번째 Point 구조체입니다.The second Point structure to compare.

Returns

Boolean

point1point2XY 좌표가 모두 같으면 true이고, 그렇지 않으면 false입니다.true if both the X and Y coordinates of point1 and point2 are equal; otherwise, false.

Examples

다음 예제에서는 두 가지 경우를 확인 하는 방법을 보여 줍니다 Point 구조체가 다른 오버 로드 된 (= =) 연산자를 사용 합니다.The following example shows how to check if two Point structures are equal using the overloaded (==) operator.

private Boolean overloadedEqualityOperatorExample()
{
    Point point1 = new Point(10, 5);
    Point point2 = new Point(15, 40);

    // Check if two Points are equal using the overloaded equality operator.
    // areEqual is False.
    Boolean areEqual = (point1 == point2);

    return areEqual;
}
Private Function overloadedEqualityOperatorExample() As Boolean
    Dim point1 As New Point(10, 5)
    Dim point2 As New Point(15, 40)

    ' Check if two Points are equal using the overloaded equality operator.
    ' areEqual is False.
    Dim areEqual As Boolean = (point1 = point2)

    Return areEqual

End Function

Remarks

사용 하 여 점의 좌표는 설명 Double 값입니다.A point's coordinates are described using Double values. 때문에 값 Double 간 비교에서 산술 작업을 수행할 때 정밀도 떨어질 수 Point 논리적으로 동일한 값을 실패할 수 있습니다.Because the value of Double can lose precision when arithmetic operations are performed on them, a comparison between two Point values that are logically equal might fail.
