Hodnota X-souřadnice této Point struktury. Výchozí hodnota je 0.

Příklady

Následující příklad ukazuje, jak zkontrolovat, jestli se dvě Point struktury nerovnají. Ukazuje také, jak přiřadit hodnoty ke Point struktuře, když je struktura deklarována a po deklaraci struktury.

// 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;
}
