Point.X Свойство

Определение

Получает или задает значение координаты X этой структуры Point.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``

Значение свойства

Значение координаты X этой структуры Point.The X-coordinate value of this Point structure. Значение по умолчанию — `0`.The default value is `0`.

Примеры

В следующем примере показано, как проверить, не Point равны ли две структуры.The following example shows how to check if two Point structures are not equal. Также показано, как присвоить значения Point структуре при объявлении структуры и после объявления структуры.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;
}
