# Vector3D.XVector3D.XVector3D.XVector3D.X Property

## Definition

Ruft die X-Komponente dieser Vector3D-Struktur ab oder legt diese fest.Gets or sets the X component of this Vector3D 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

Die X-Komponente dieser Vector3D-Struktur.The X component of this Vector3D structure. Der Standardwert ist `0`.The default value is `0`.

## Beispiele

Das folgende Beispiel zeigt, wie berechnet das Skalarprodukt von zwei Vector3D Strukturen.The following example shows how to calculate the dot product of two Vector3D structures. Darüber hinaus erfahren Sie, wie Werte zu einem Vector3D Struktur, während die Struktur deklariert wird und nachdem die Struktur deklariert wurde.It also shows how to assign values to a Vector3D structure when the structure is being declared and after the structure has been declared.

``````// 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
