使用指定的實數和虛數,初始化 Complex 結構的新執行個體。
public:
Complex(double real, double imaginary);
C#
public Complex(double real, double imaginary);
new System.Numerics.Complex : double * double -> System.Numerics.Complex
Public Sub New (real As Double, imaginary As Double)
- real
- Double
複數的實數部分。
- imaginary
- Double
複數的虛數部分。
下列範例會具現化兩個複數,然後另外使用複數、減法、乘法和除法運算。
C#
using System;
using System.Numerics;
public class Example
{
public static void Main()
{
Complex complex1 = new Complex(17.34, 12.87);
Complex complex2 = new Complex(8.76, 5.19);
Console.WriteLine("{0} + {1} = {2}", complex1, complex2,
complex1 + complex2);
Console.WriteLine("{0} - {1} = {2}", complex1, complex2,
complex1 - complex2);
Console.WriteLine("{0} * {1} = {2}", complex1, complex2,
complex1 * complex2);
Console.WriteLine("{0} / {1} = {2}", complex1, complex2,
complex1 / complex2);
