# Complex.Addition 运算符

## 重载

 Addition(Complex, Complex) 将两个复数相加。Adds two complex numbers. Addition(Double, Complex) 将一个双精度实数与一个复数相加。Adds a double-precision real number to a complex number. Addition(Complex, Double) 将一个复数与一个双精度实数相加。Adds a complex number to a double-precision real number.

## 示例

``````using System;
using System.Numerics;

public class Example
{
public static void Main()
{
Complex[] values= { new Complex(12.3, -1.4),
new Complex(-6.2, 3.1),
new Complex(8.9, 1.5) };
foreach (var c1 in values)
foreach (var c2 in values)
Console.WriteLine("{0} + {1} = {2}", c1, c2, c1 + c2);
}
}
// The example displays the following output:
//       (12.3, -1.4) + (12.3, -1.4) = (24.6, -2.8)
//       (12.3, -1.4) + (-6.2, 3.1) = (6.1, 1.7)
//       (12.3, -1.4) + (8.9, 1.5) = (21.2, 0.1)
//       (-6.2, 3.1) + (12.3, -1.4) = (6.1, 1.7)
//       (-6.2, 3.1) + (-6.2, 3.1) = (-12.4, 6.2)
//       (-6.2, 3.1) + (8.9, 1.5) = (2.7, 4.6)
//       (8.9, 1.5) + (12.3, -1.4) = (21.2, 0.1)
//       (8.9, 1.5) + (-6.2, 3.1) = (2.7, 4.6)
//       (8.9, 1.5) + (8.9, 1.5) = (17.8, 3)

## 注解

Addition 运算符允许执行涉及复数的加法运算。The Addition operator allows performing addition 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 = new Complex(1.2, 2.3);
Complex c2 = new Complex(2.1, 3.2);
Complex c3 = c1 + c2;
``````
``````Dim c1 As New Complex(1.2, 2.3)
Dim c2 As New Complex(2.1, 3.2)
Dim c3 As Complex = c1 + c2
``````

## Addition(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` 的和。The sum of `left` and `right`.

### 注解

（a + c） + （b + d） i(a + c) + (b + d)i

## Addition(Double, Complex)

``````public:
