示例

以下示例演示如何检查两 Point 个结构是否不相等。 它还说明了在声明结构时以及如何在声明结构之后向结构赋值 Point 。

// Checks if two Points are equal using the overloaded inequality operator.
private Boolean pointInequalityExample()
{
    // Checks if two Points are not equal using the overloaded inequality operator.

    // Declaring point1 and initializing x,y values
    Point point1 = new Point(10, 5);

    // Declaring point2 without initializing x,y values
    Point point2 = new Point();

    // Boolean to hold the result of the comparison
    Boolean areNotEqual;

    // assigning values to point2
    point2.X = 15;
    point2.Y = 40;

    // Compare Point structures for equality.
    // areNotEqual is True
    areNotEqual = (point1 != point2);

    return areNotEqual;
}

' Checks if two Points are equal using the overloaded inequality operator.
Private Function pointInequalityExample() As Boolean
    ' Checks if two Points are not equal using the overloaded inequality operator.

    ' Declaring point1 and initializing x,y values
    Dim point1 As New Point(10, 5)

    ' Declaring point2 without initializing x,y values
    Dim point2 As New Point()

    ' Boolean to hold the result of the comparison
    Dim areNotEqual As Boolean

    ' assigning values to point2
    point2.X = 15
    point2.Y = 40

    ' Compare Point structures for equality.
    ' areNotEqual is True
    areNotEqual = (point1 <> point2)

    Return areNotEqual

End Function

注解

在 XAML 中XY，分隔符与值Point之间的分隔符可以是逗号或空格。

某些区域性可能会使用逗号字符作为小数分隔符，而不是句点字符。 固定区域性的 XAML 处理默认在大多数 XAML 处理器实现中 en-US，并且预期句点为小数分隔符。 如果在 XAML 中指定Point字符，则应避免使用逗号字符作为小数分隔符，因为这将与属性值的字符串类型转换Point和XY组件冲突。

XAML 属性用法

<object property="x,y"/>
-or-
<object property="x y"/>

XAML 值

x 此对象的 Pointx 坐标。

y 的 y 坐标 Point。
