Answer 1

谢谢过楼上的了，去看了一下，不过都是用VB编的，我以前没有学过VB，不知道用C#怎么编写？

Answer 2

public struct Complex
{
    public int real;
    public int imaginary;    public Complex(int real, int imaginary)  //constructor
    {
        this.real = real;
        this.imaginary = imaginary;
    }    // Declare which operator to overload (+),
    // the types that can be added (two Complex objects),
    // and the return type (Complex):
    public static Complex operator +(Complex c1, Complex c2)
    {
        return new Complex(c1.real + c2.real, c1.imaginary + c2.imaginary);
    }    // Override the ToString() method to display a complex number in the traditional format:
    public override string ToString()
    {
        return (System.String.Format("{0} + {1}i", real, imaginary));
    }
}class TestComplex
{
    static void Main()
    {
        Complex num1 = new Complex(2, 3);
        Complex num2 = new Complex(3, 4);        // Add two Complex objects through the overloaded plus operator:
        Complex sum = num1 + num2;        // Print the numbers and the sum using the overriden ToString method:
        System.Console.WriteLine("First complex number:  {0}", num1);
        System.Console.WriteLine("Second complex number: {0}", num2);
        System.Console.WriteLine("The sum of the two numbers: {0}", sum);
    }
}//一个简单的复数类。。

        public static Complex operator -(Complex c1, Complex c2) //重载"-"运算符

        public static bool operator > (Complex c1,Complex c2)//重载">"运算符

     }        public static bool operator ==(Complex c1, Complex c2)//重载"<"运算符
     {
            if ((c1.real == c2.real) && (c1.imaginary == c2.imaginary))
                return true;
             else return false;
     }
          
         public static bool operator !=(Complex c1,Complex c2)
{
if((c1.real==c2.real)&&(c1.imaginary==c2.imaginary))
 return false;
else return true;
}
        public override string ToString( )
        {
            return (String.Format("{0} + {1} I", real, imaginary));
        }
        /// <summary>
        /// 应用程序的主入口点。
        /// </summary>
        
        public static void Main(  )
        {
               Complex value1= new  Complex(4,3);
               Complex value2 = new Complex(5,4);
               Complex sum = value1 + value2;
               Console.WriteLine("第一个复数是：  {0}",value1);
               Console.WriteLine("第二个复数是：  {0}", value2);
               Console.WriteLine("两个复数的和是： {0}", sum);
              
               
  
           
        }
    }
}
这是自己编的，怎么也运行不出来,不知道问题出在哪里？？？？？？？？？？
