範例

此範例展示了如何 Vector3D 利用過載減法（-）運算子和 Vector3D 靜態 Subtract 方法來減去結構。

以下程式碼說明如何使用 Vector3D 減法方法。 首先， Vector3D 結構被實例化。 Vector3D結構會用過載（-）運算子減去，然後再用靜態Subtract方法減去結構。

// Subtracts two 3-D Vectors using the Subtract method and -

// 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();

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

// Subtracting vectors using overload - operator
Vector3D vectorResult1 = new Vector3D();
vectorResult1 = vector1 - vector2;
// vectorResult1 is equal to (-25, -40, -40)

// Subtracting vectors using static Subtract method
Vector3D vectorResult2 = new Vector3D();
vectorResult2 = Vector3D.Subtract(vector1, vector2);
// vector2 is equal to (-25, -40, -40)
