未经处理的异常: System.IO.FileNotFoundException: 未能加载文件或程序集“accessDA
1.调试时出现图片：上面写着：“System.IO.FileNotFoundException”类型的未经处理的异常出现在 mscorlib.dll 中。
其他信息: 未能加载文件或程序集“accessDAL”或它的某一个依赖项。系统找不到指定的文件
2.工厂(DALFactor)的代码：using System;
using System.Reflection;
namespace DALFactory
{
public sealed class DataAccess
{
private static string path = "accessDAL";
public static object CreateObject(string className)
{
string classname = path + "." + className;
return Assembly.Load(path).CreateInstance(classname);
}
}
3.实现类accessDAL的代码：using System;
using System.Collections.Generic;
using System.Data.OleDb;
namespace accessDAL
{
public class ABook:IDAL.IBook
{
private static string conn = "Provider=Microsoft.Jet.OleDb.4.0;Data Source='I:/软件工程/book.mdb'";
public Model.Book getBook(string b_name)
{
string sqlstring = "select * from book where b_name like " + "'%" + b_name + "%'";
OleDbConnection ole = new OleDbConnection(conn);
OleDbCommand dbc = new OleDbCommand(sqlstring, ole);
ole.Open();
OleDbDataReader p = dbc.ExecuteReader();
if (p.Read() == true)
return new Model.Book(p.GetString(0), p.GetFloat(1), p.GetInt32(2), p.GetString(3));
else
return null;
}
}
}

本人经过各种努力，还是解决不了该问题。。。实在没辙了，希望各位大神帮帮小弟
[解决办法]
你需要加载的dll相关文件在不在运行目录下？
给几个链接看看吧：
