## 定義

Vector3D 結構加入至 Point3D 結構，或加入至另一個 Vector3D 結構。Adds a Vector3D structure to a Point3D structure or to another Vector3D structure.

## 多載

 將兩個 Vector3D 結構相加，並傳回結果做為 Vector3D 結構。Adds two Vector3D structures and returns the result as a Vector3D structure. 依指定的 Point3D 結構平移指定的 Vector3D 結構，並傳回結果做為 Point3D 結構。Translates the specified Point3D structure by the specified Vector3D structure and returns the result as a Point3D structure.

static System::Windows::Media::Media3D::Vector3D operator +(System::Windows::Media::Media3D::Vector3D vector1, System::Windows::Media::Media3D::Vector3D vector2);``````
``public static System.Windows.Media.Media3D.Vector3D operator + (System.Windows.Media.Media3D.Vector3D vector1, System.Windows.Media.Media3D.Vector3D vector2);``
``static member ( + ) : System.Windows.Media.Media3D.Vector3D * System.Windows.Media.Media3D.Vector3D -> System.Windows.Media.Media3D.Vector3D``
``Public Shared Operator + (vector1 As Vector3D, vector2 As Vector3D) As Vector3D``

vector1
Vector3D

vector2
Vector3D

#### 傳回

`vector1``vector2` 的總和。The sum of `vector1` and `vector2`.

### 範例

``````// Adds a Vector3D to a Vector3D using the overloaded + operator.
// Returns a Vector3D.

Vector3D vector1 = new Vector3D(20, 30, 40);
Vector3D vector2 = new Vector3D(45, 70, 80);
Vector3D vectorResult = new Vector3D();

vectorResult = vector1 + vector2;
// vectorResult is equal to (65, 100, 120)
``````
