Vector.Equality(Vector, Vector) 操作员

public:
 static bool operator ==(System::Windows::Vector vector1, System::Windows::Vector vector2);

public static bool operator ==(System.Windows.Vector vector1, System.Windows.Vector vector2);

static member ( = ) : System.Windows.Vector * System.Windows.Vector -> bool

Public Shared Operator == (vector1 As Vector, vector2 As Vector) As Boolean

参数

返回

如果和组件相等，则为 />;否则为 >。

示例

以下示例演示如何使用此运算符 （==） 检查两 Vector 个结构是否相等。

private Boolean overloadedEqualityOperatorExample()
{
    Vector vector1 = new Vector(20, 30);
    Vector vector2 = new Vector(45, 70);

    // If the two vectors are equal, areEqual is True,
    // otherwise it is False. In this example it is False.
    Boolean areEqual = (vector1 == vector2);

    return areEqual;
}

Private Function overloadedEqualityOperatorExample() As Boolean
    Dim vector1 As New Vector(20, 30)
    Dim vector2 As New Vector(45, 70)

    ' If the two vectors are equal, areEqual is True,
    ' otherwise it is False. In this example it is False.
    Dim areEqual As Boolean = (vector1 = vector2)

    Return areEqual

End Function

注解

使用值描述X向量Y和Double属性。 由于算术运算对它执行算术运算时的值 Double 可能会丢失精度，因此在逻辑上相等的两 Vector 个结构之间的比较可能会失败。
