C#通过反射调用程序集DLL类中的方法_补充第3篇

1、直接上代码
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Reflection;
namespace _11调用方法
{
class Program
{
static void Main(string[] args)
{
Type stu = typeof(Student);
// 1、string
//MethodInfo meth = stu.GetMethod(“Say”, new Type[] { typeof(string) });
// object obj = Activator.CreateInstance(stu);
// meth.Invoke(obj, new object[] { “你好啊” });
// Console.ReadKey();

        // 2、int
        //**MethodInfo** meth = stu.**GetMethod**("Say", new Type[] { typeof(int) });
        //object obj = **Activator**.CreateInstance(stu);
        //meth.Invoke(obj, new object[] { 23 });
        //Console.ReadKey();


        // 3、无参
        MethodInfo meth = stu.GetMethod("Say", new Type[] { });
        object obj = Activator.CreateInstance(stu);
        meth.Invoke(obj, null);
        Console.ReadKey();
    }

    public class Student
    {
        public void Say(string str)
        {
            Console.WriteLine("++++++++++++++ " + str);
        }
        public void Say(int num)
        {
            Console.WriteLine(num);
        }
        public void Say()
        {
            Console.WriteLine("------------------- ");
        }
    }
}

}
