1、实验 1 熟悉 C#语言：数组和类的定义实验目的：理解 C#的基本概念及其基本操作，重点是数组的处理和新的类型的定义。题意：1. 定义和初始化数组，在数组中查找特定数据，对数组中的数据进行排序。2. 设计复数类，实现复数的基本操作。1. 泛型方法C#语言中泛型的优越性在下面的一段例子中应能较好的显示出来。对于同样的运算逻辑（例子中是交换两个变量的内容） ，但仅是数据的类型不一样，可能就需要定义一堆相似的方法；而应用泛型特性则可仅定义一个泛型方法（例子中是 swap） 。static void Main(string args) int a = 3; int b = 7;swapint(ref
2、a, ref b);double ad = 3.5; double bd = 7.5;swapdouble(ref ad, ref bd);swap(ref a, ref b);static void swapint(ref int a, ref int b) int x = a;a = b;b = x;static void swapdouble(ref double a, ref double b) double x = a;a = b;b = x;static void swap(ref T a, ref T b) T x = a;a = b;b = x; 2. 定义和初始化数组，在数组
3、中查找特定数据，对数组中的数据进行排序。class Program static void Main(string args) int a = new int20;RandomizeData(a);Show(a);int i = Array.IndexOf(a, 10);Console.WriteLine(10s index is: 0, i);Console.WriteLine(Sorted Array: );Array.Sort(a);Show(a);private static void Show(int a) for (int i = 0; i (ca, new Complex();i
4、nt i = Array.IndexOf(ca, ca5);Console.WriteLine(0s index is: 1, ca5, i);Console.WriteLine(Sorted Array: ); Array.Sort(ca);Show(ca);private static void Show(Complex a) for (int i = 0; i 0)s = rp.ToString(F) + + + ip.ToString(F) + j;else if (ip 0)s = ip.ToString(F) + j;else if (ip = Math.Abs(c.ip) e =
5、 c.ip / c.rp;f = c.rp + e * c.ip;x = (rp + ip * e) / f;y = (ip - rp * e) / f;else e = c.rp / c.ip;f = c.ip + e * c.rp;rp = (rp * e + ip) / f;ip = (ip * e - rp) / f;return this;/* 计算复数的模* * return double型，指定复数的模*/public double Abs() return (Math.Sqrt(rp*rp +ip*ip);/* 计算复数的实幂指数* * param x - 待求实幂指数的幂次*
