# Vector3D.Y プロパティ

## 定義

この Vector3D 構造体の Y コンポーネントを取得または設定します。Gets or sets the Y component of this Vector3D structure.

``````public:
property double Y { double get(); void set(double value); };``````
``public double Y { get; set; }``
``member this.Y : double with get, set``
``Public Property Y As Double``

#### プロパティ値

Double

この Vector3D 構造体の Y コンポーネント。The Y component of this Vector3D structure. 既定値は `0` です。The default value is `0`.

## 例

``````    // 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)
