1、usingSystem;usingSystem.Collections.Generic;usingSystem.Text;namespace_010921{classComplexNumber{privatedoublereal,image;publicComplexNumber()//无参构造函数{real=0;image=0;}publicComplexNumber(doubler)//只有实部的构造函数{real=r;image=0;}publicComplexNumber(doubler,doublei)//含有实部和

2、虚部的构造函数{real=r;image=i;}publicdoubleReal//实部{set{real=value;}get{returnreal;}}publicdoubleImage//虚部{set{image=value;}get{returnimage;}}publicComplexNumberAddComplex(ComplexNumberc1,ComplexNumberc2)//复数c1与c2相加{returnnewComplexNumber(c1.real+c2.real,c1.image+c2.image)

3、;}publicComplexNumberSubComplex(ComplexNumberc1,ComplexNumberc2)//复数c1与c2相减{returnnewComplexNumber(c1.real-c2.real,c1.image-c2.image);}publicComplexNumberMultiplyComplex(ComplexNumberc1,ComplexNumberc2)//复数c1与c2相乘{returnnewComplexNumber(c1.real*c2.real-c1.image*c2.i

6、dLine());Console.WriteLine("请输入第一个复数的虚部:");c1.Image=double.Parse(Console.ReadLine());Console.WriteLine("请输入第二个复数的实部:");c2.Real=double.Parse(Console.ReadLine());Console.WriteLine("请输入第二个复数的虚部:");c2.Image=double.Parse(Console.ReadLine());Console.WriteLine("您输入的第一个复数c1
