C#使用Dynamic实现简化反射

class Program
    {
        static void Main(string[] args)
        {
            int times = 1;
            DynamicSample dynamicSample = new DynamicSample();
            var addMethod = typeof(DynamicSample).GetMethod("Add");
            Stopwatch watch1 = Stopwatch.StartNew();
            int result = 0;
            for (int i = 0; i < times; i++)
            {
                result = (int)addMethod.Invoke(dynamicSample, new object[] { 1, 2 });
            }
            Console.WriteLine(string.Format("正常的反射耗时：{0}毫秒", watch1.ElapsedMilliseconds));
            Console.WriteLine("正常反射的结果："+result);
            dynamic dynamicSample2 = new DynamicSample();
            int result2 = 0;
            Stopwatch watch2 = Stopwatch.StartNew();
            for (int i = 0; i < times; i++)
            {
                result2 = dynamicSample2.Add(1, 2);
            }
            Console.WriteLine(string.Format("Dynamic的反射耗时：{0}毫秒", watch2.ElapsedMilliseconds));
            Console.WriteLine("Dynamic反射的结果："+result2);
            DynamicSample reflectSamplebetter = new DynamicSample();
            var addMethod2 = typeof(DynamicSample).GetMethod("Add");
            var delg = (Func<DynamicSample, int, int, int>)Delegate.CreateDelegate(typeof(Func<DynamicSample, int, int, int>), addMethod2);
            int result3 = 0;
            Stopwatch watch3 = Stopwatch.StartNew();
            for (int i = 0; i < times; i++)
            {
                result3=delg(reflectSamplebetter,1,2);
            }
            Console.WriteLine(string.Format("优化的反射耗时：{0}毫秒", watch3.ElapsedMilliseconds));
            Console.WriteLine("优化的反射结果："+result3);
            Console.Read();
        }
    }

public class DynamicSample
    {
        public string Name { get; set; }
        public int Add(int a, int b)
        {
            return a + b;
        }
