C# 关于自定义泛型类，泛型方法，泛型接口 <实现算法重用>
1.main 调用处代码段

        static void Main(string[] args)
        {
            IFactory<string, string, int, string, int, double> fct = new MyClass<string, string, int, string, int, double>();
            var eat1 = fct.Eat();
            Console.WriteLine("eat1返回值：{0}",eat1);

            fct.Eat("我爱吃大熊猫");

            var sayhi1=fct.sayHi();
            Console.WriteLine(sayhi1);

            var sayhello1 = fct.sayHello("写轮眼");
            Console.WriteLine("sayhello1返回值：{0}", sayhello1);

            Console.ReadKey();
        }

2.泛型接口代码段

 /// <summary>
    /// 泛型接口
    /// </summary>
    /// <typeparam name="T"></typeparam>
    /// <typeparam name="U"></typeparam>
    /// <typeparam name="V"></typeparam>
    /// <typeparam name="HL"></typeparam>
    /// <typeparam name="W"></typeparam>
    /// <typeparam name="HE"></typeparam>
    public interface IFactory<T, U, V, HL, W, HE>
    {
        T sayHi();//返回值泛型
        HL sayHello(U msg);//参数泛型
        V Eat();
        void Eat(HL str);
    }

3.泛型类&泛型方法 代码段

/// <summary>
    /// 泛型类实现泛型接口
    /// </summary>
    /// <typeparam name="T">string</typeparam>
    /// <typeparam name="U">string</typeparam>
    /// <typeparam name="V">int</typeparam>
    /// <typeparam name="HL">string</typeparam>
    /// <typeparam name="W">int</typeparam>
    /// <typeparam name="HE">double</typeparam>
    public class MyClass<T, U, V, HL, W, HE> : IFactory<T, U, V, HL, W, HE>
    {
        /// <summary>
        /// 返回值泛型
        /// </summary>
        /// <returns></returns>
        public V Eat()
        {
            object obj = 5;
            return (V)obj;
        }

        /// <summary>
        /// 参数列表泛型
        /// </summary>
        /// <param name="str"></param>
        public void Eat(HL str)
        {
            Console.WriteLine(str);
        }

        /// <summary>
        /// 参数列表&返回值均泛型
        /// </summary>
        /// <param name="msg"></param>
        /// <returns></returns>
        public HL sayHello(U msg)
        {
            Console.WriteLine("这是sayHello泛型方法参数：{0}", msg);
            object rest = (object)msg;
            return (HL)rest;
        }

        public T sayHi()
        {
            object ret = "小鸟说早早早";
            return (T)ret;
        }
    }
