通过反射获取DLL的类实现加载窗体

namespace Testassembly
{
    public partial class Form1 : Form
    {
        public Form1()
        {
            InitializeComponent();
        }

        private void Form1_Load(object sender, EventArgs e)
        {
            string ss = AppDomain.CurrentDomain.BaseDirectory + "Debug\\TestDll.dll";
            Assembly assembly = Assembly.LoadFile(ss);

            //获取类型，参数（名称空间+类）   
            Type type = assembly.GetType("TestDll.Form1");

            //创建该对象的实例，object类型，参数（名称空间+类）   
            
           // System.Reflection.MethodInfo method = type.GetMethod("Show");//方法的名称
            object instance = assembly.CreateInstance("TestDll.Form1");
            Form frm = (Form)instance;
            frm.Show();
           // method.Invoke(instance,Object[] parametors = new Object[] { "param" });
        }
    }
}
