應用反射動態調用類庫中的各類的方法

namespace ClassLibrary1
{
    public class  Translation
    {
        public Translation()
        {
        }

        public virtual string reuturn()
        {
            return "this is 交通工具";
        }
    }

    public class car:Translation
    {
        public override string reuturn()
        {
            return "this is 汽車";
        }
    }

    public class ship:Translation
    {
        public override string reuturn()
        {
            return "this is 輪船";
        }
    }

    public class plan:Translation
    {
        public override string reuturn()
        {
            return "this is 飛機";
        }
    }
}

用反射的方法獲得對該類庫方法的使用

class Program
    {
        static void Main(string[] args)
        {

            System.Reflection.Assembly a = System.Reflection.Assembly.LoadFile
                    (@"C:\Documents and Settings\Administrator\桌面\C#\TEST\ClassLibrary1.dll");
            Type[] c= a.GetTypes();
           
            foreach (Type objType in c)
            {
                string b = objType.ToString();
               
              // string aaaa= a.CreateInstance(b).reuturn();

                object objClass = a.CreateInstance(b);

                System.Reflection.MethodInfo moth = objType.GetMethod("reuturn");

                Console.WriteLine(moth.Invoke(objClass,null));
            }

            Console.ReadLine();
        }
    }
