Vector3D.X Proprietà

Definizione

Ottiene o imposta il componente X di questa struttura Vector3D.

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

Valore della proprietà

Double

Componente X di questa struttura Vector3D. Il valore predefinito è 0.

Esempio

Nell'esempio seguente viene illustrato come calcolare il prodotto punto di due Vector3D strutture. Viene inoltre illustrato come assegnare valori a una Vector3D struttura quando la struttura viene dichiarata e dopo che la struttura è stata dichiarata.

    // Calculates the Dot Product of two Vectors.

    // Declaring vector1 and initializing x,y,z values
    Vector3D vector1 = new Vector3D(20, 30, 40);

    // Declaring vector2 without initializing x,y,z values
    Vector3D vector2 = new Vector3D();

    // A Double to hold the result of the operation
    Double dotProduct;

    // Assigning values to vector2
    vector2.X = 45;
    vector2.Y = 70;
    vector2.Z = 80;

    // Calculating the dot product of vector1 and vector2
    dotProduct = Vector3D.DotProduct(vector1, vector2);

    // vectorResult is equal to (6200)
' Calculates the Dot Product of two Vectors.

' Declaring vector1 and initializing x,y,z values
Dim vector1 As New Vector3D(20, 30, 40)

' Declaring vector2 without initializing x,y,z values
Dim vector2 As New Vector3D()

' A Double to hold the result of the operation
Dim dotProduct As Double

' Assigning values to vector2
vector2.X = 45
vector2.Y = 70
vector2.Z = 80

' Calculating the dot product of vector1 and vector2
dotProduct = Vector3D.DotProduct(vector1, vector2)

' vectorResult is equal to (6200)
