反射的总结

1.反射的可扩展性，可以把要加载的dll文件放在App.config中

<?xml version="1.0" encoding="utf-8" ?>
<configuration>
  <startup>
    <supportedRuntime version="v4.0" sku=".NETFramework,Version=v4.5.2" />
  </startup>
  <appSettings>
    <add key="ConsoleApplication1" value="ConsoleApplication1.dll"/>
  </appSettings>
</configuration>

2.使用反射创建对象并调用方法

        private void button1_Click(object sender, EventArgs e)
        {
            var assembly = Assembly.Load("ConsoleApplication1");
            Type[] trye = assembly.GetTypes();
            object obj = Activator.CreateInstance(trye[0]);

            Console.WriteLine("----------GetModules--------------");
            foreach (var item in assembly.GetModules())
            {
                Console.WriteLine(item.Name);
            }

            Console.WriteLine("----------GetMethods--------------");
            foreach (var item in trye[0].GetMethods())
            {
                Console.WriteLine(item.Name);
                //item.Invoke(obj, null);
            }

            MethodInfo methodinfo = trye[0].GetMethod("SayGoodmorning");
            methodinfo.Invoke(obj, null);

        }

3.使用反射找重载的方法 public MethodInfo GetMethod(string name, Type[] types);
