# Complex.Multiply 运算符

## 重载

 Multiply(Complex, Complex) 将两个指定复数相乘。Multiplies two specified complex numbers. Multiply(Double, Complex) 将一个指定双精度实数乘以一个指定复数。Multiplies a specified double-precision real number by a specified complex number. Multiply(Complex, Double) 将一个指定复数乘以一个指定双精度实数。Multiplies the specified complex number by a specified double-precision real number.

## 注解

Multiply 运算符允许执行涉及复数的乘法运算。The Multiply operator allows performing multiplication operations that involve complex numbers. 它可以实现如下所示的代码：It enables code such as the following:

``````Complex c1 = Complex.One;
Complex c2 = new Complex(1.4, 2.3);
Complex c3 = c1 * c2;
``````
``````Dim c1 As Complex = Complex.One
Dim c2 As New Complex(1.4, 2.3)
Dim c3 As Complex = c1 * c2
``````

## Multiply(Complex, Complex)

``````public:
static System::Numerics::Complex operator *(System::Numerics::Complex left, System::Numerics::Complex right);``````
``public static System.Numerics.Complex operator * (System.Numerics.Complex left, System.Numerics.Complex right);``
``static member ( * ) : System.Numerics.Complex * System.Numerics.Complex -> System.Numerics.Complex``
``Public Shared Operator * (left As Complex, right As Complex) As Complex``

left
Complex

right
Complex

#### 返回

`left``right` 的乘积。The product of `left` and `right`.

### 注解

（ac-bd） + （ad + bc） i(ac - bd) + (ad + bc)i

## Multiply(Double, Complex)

``````public:
static System::Numerics::Complex operator *(double left, System::Numerics::Complex right);``````
``public static System.Numerics.Complex operator * (double left, System.Numerics.Complex right);``
``static member ( * ) : double * System.Numerics.Complex -> System.Numerics.Complex``
``Public Shared Operator * (left As Double, right As Complex) As Complex``

left
Double

right
Complex

#### 返回

`left``right` 的乘积（为复数）。The product of `left` and `right`, as a complex number.

## Multiply(Complex, Double)
