Public Shared Operator - (vector1 As Vector3D, vector2 As Vector3D) As Vector3D

参数

vector1
Vector3D

作为被减数的 Vector3D 结构。

vector2
Vector3D

要从 vector1 中减去的 Vector3D 结构。

返回

vector2vector1 所得的结果。

示例

下面的示例演示如何使用重载减法运算符从 Vector3D 结构中减去 Vector3D 结构。

// Subtracts a Vector3D from 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;
// vector Result is equal to (-25, -40, -40)
' Subtracts a Vector3D from a Vector3D using the overloaded - operator.  
' Returns a Vector3D.

Dim vector1 As New Vector3D(20, 30, 40)
Dim vector2 As New Vector3D(45, 70, 80)
Dim vectorResult As New Vector3D()

vectorResult = vector1 - vector2
' vector Result is equal to (-25, -40, -40)
