请教，用C#写一个复数类！

[bufan2000]

写一个复数类，实现
（1）构造函数重载（三种：缺省，实部＋虚部，幅角＋模）
（2）实现＋，－，×，/运算，尤其是注意/运算分母不等于零，包含和整数，和浮点数，和复数相乘的情况。
（3）定义>，<,==,!=等
（4）实现实数到复数的转换（显式，隐式），实现复数到实数的转换（显式，隐式），如果可以的话，如果不可以请显示错误信息。
请各位大侠，帮帮忙！！！

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？

[hooo]

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。。

帮顶一下,这个应该不难,不过得花点时间,我现在做项目遇到问题了暂时没空.如果问题解决了帮你写出来

这一步怎么实现呢?还是不会啊

这是自己编的，怎么也运行不出来,不知道问题出在哪里？？？？？？？？？？
