关于反射的一个问题，懂得进来帮我看下代码！！！！！！！！

Question

程序 using System;using System.Collections.Generic;using System.ComponentModel;using System.Data;using System.Drawing;using System.Text;using System.Windows.Forms; using System.Reflection; namespace Test{    public partial class Form3 : Form    {        public Form3()        {            InitializeComponent();        }         private object Invoke(string lpFileName, string Namespace, string ClassName, string lpProcName)        {            try            { // 载入程序集                 Assembly MyAssembly = Assembly.LoadFrom(lpFileName);                Type[] type = MyAssembly.GetTypes();                foreach (Type t in type)                {// 查找要调用的命名空间及类                     if (t.Namespace == Namespace && t.Name == ClassName)                    {// 查找要调用的方法并进行调用                         MethodInfo m = t.GetMethod(lpProcName);                        if (m != null)                        {                            object o = Activator.CreateInstance(t);                            return m.Invoke(o, null);                        }                        else MessageBox.Show(" 装载出错 !");                    }                }            }//try             catch (System.NullReferenceException e)            {                MessageBox.Show(e.Message);            }//catch             return (object)0;         }         private void button1_Click(object sender, EventArgs e)        {            MessageBox.Show(" 点击获取字符串 " + Invoke("DataLogic.dll", "DataLogic", "Form1", "getArray").ToString());         }    }} 被调用的DLL程序 using System;using System.Collections.Generic;using System.ComponentModel;using System.Data;using System.Drawing;using System.Text;using System.Windows.Forms; namespace DataLogic{    public partial class Form1 : Form    {                public Form1()        {            InitializeComponent(); 　　}          public string getArray()        {             string va = "aaaaaa";            return va;        } 我只是想反射得到getArray()方法里“aaaaaa”,不知道为什么object o = Activator.CreateInstance(t);报错，我不知道错在哪了，大家帮我看下。

你的代码没有问题，我试过，再查查dll的引用，invoke的参数是否传对了。
