Point.X Eigenschaft

Definition

Ruft den X-Koordinatenwert dieser Point-Struktur ab oder legt den Wert fest.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

Eigenschaftswert

Der X-Koordinatenwert dieser Point-Struktur.The X-coordinate value of this Point structure. Der Standardwert ist 0(null).The default value is 0.

Beispiele

Im folgenden Beispiel wird gezeigt, wie Sie über Point prüfen können, ob zwei-Strukturen ungleich sind.The following example shows how to check if two Point structures are not equal. Außerdem wird veranschaulicht, wie einer Point Struktur Werte zugewiesen werden, wenn die Struktur deklariert wird und nachdem die Struktur deklariert wurde.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
