关于反射

[xiaosong8023]

请问各位大大,要怎么才能反射.net中的内置对象,如:System.Data.SqlClient.SqlDataAdapter

给你个例子，自己参考做。

使用反射查看某个dll文件的实现

string _strPath = AppDomain.CurrentDomain.BaseDirectory;

            string str = _strPath + "Platform.dll";

            Assembly m_Assembly = Assembly.LoadFrom(str);//载入装配件


//枚举一个dll下的成员

        static void EnumCls(Assembly m_Assembly)

        {

            Type[] types = m_Assembly.GetTypes();

            foreach (Type t in types)

            {

                Console.WriteLine(t.Name);

            }

        }

使用反射调用某个dll文件下的方法

string str = _strPath + "BLL.dll";

            Assembly m_Assembly = Assembly.LoadFrom(str);//载入装配件

            string clsName = "Bll";

            object o = ActivetorMethodOutObject(clsName, m_Assembly);//返回装配件下的类

            Bll bl = (Bll)o;

            bl.Greeting();

//返回指定dll下的类

        static object ActivetorMethodOutObject(string clsName,Assembly m_Assembly)

        {

            object _result = null;

            try

            {

                string _tmpCls = "BLL." + clsName;

                Type _CurrentType = m_Assembly.GetType(_tmpCls,false);

                _result = Activator.CreateInstance(_CurrentType);

            }

            catch { }

            return _result;

        }

BLL.dll

using System;

using System.Collections.Generic;

using System.Text;


namespace BLL

{

    public class Bll

    {

        public void Greeting()

        {

            Console.WriteLine("Hello from your classmate DongYi Wang,who is now working in ShangHai " +

                "as a coder,he sometimes miss you very much.How time flies,it's almost 4 years since " +

                "the last meet.Thanks for your gift.Remember me to your family and wish you success." +

                "Enjoy every day.Keep touching.yours sincerely.");

        }

    }

}

Reflector工具可以很方便的反射dll文件

[wzp144650]

用反射调用那个DLL

[xiaosong8023]

还要找到SqlDataAdapter的.dll文件吗?
