Point.Inequality(Point, Point) 运算符

定义

命名空间:

System.Windows

程序集:

WindowsBase.dll

比较两个 Point 结构是否不相等。

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 op_Inequality : System.Windows.Point * System.Windows.Point -> bool

Public Shared Operator != (point1 As Point, point2 As Point) As Boolean

参数

point1

Point

要比较的第一个点。

point2

Point

要比较的第二个点。

返回

Boolean

如果 point1 和 point2 有不同的 X 或 Y 坐标，则为 true；如果 point1 和 point2 有相同的 X 和 Y 坐标，则为.false。

示例

以下示例演示如何使用重载的 (！=) 运算符检查两 Point 个结构是否不相等。

private Boolean overloadedInequalityOperatorExample()
{
    Point point1 = new Point(20, 30);
    Point point2 = new Point(45, 70);

    // Check whether the two Points are not equal, using the overloaded 
    // inequality operator.
    // areNotEqual is True.
    Boolean areNotEqual = (point1 != point2);

    return areNotEqual;
}

Private Function overloadedInequalityOperatorExample() As Boolean
    Dim point1 As New Point(20, 30)
    Dim point2 As New Point(45, 70)

    ' Check whether the two Points are not equal, using the overloaded 
    ' inequality operator.
    ' areNotEqual is True.
    Dim areNotEqual As Boolean = (point1 <> point2)

    Return areNotEqual

End Function

注解

使用值描述Double点和YX坐标。 由于 Double 值在操作时可能会丢失精度，因此在逻辑上相等的两 Point 个值之间的比较可能会失败。
