Point.X Point.X Point.X Point.X Property

定义

获取或设置此 X 结构的 Point 坐标值。Gets or sets the X-coordinate value of this Point structure.

public:
 property double X { double get(); void set(double value); };
public double X { get; set; }
member this.X : double with get, set
Public Property X As Double

属性值

X 结构的 Point 坐标值。The X-coordinate value of this Point structure. 默认值为0The default value is 0.

示例

下面的示例演示如何检查两个Point结构是否不相等。The following example shows how to check if two Point structures are not equal. 它还说明了在声明结构时以及Point在声明结构后如何向结构分配值。It also illustrates how to assign values to a Point structure when the structure is being declared and after the structure has been declared.

// 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
