下面就是实际调用的程序原文件using System;using System.Collections;using System.ComponentModel;using System.Drawing;using System.Web;using System.Web.SessionState;using System.Web.UI;using System.Web.UI.WebControls;using System.Web.UI.HtmlControls;using System.Text;using clubstar.IPlug;using clubstar.IPlug.DataOp;using clubstar.uc;using clubstar.DataOp;namespace clubstar{/// /// WebForm1 的摘要说明。/// public class InsertUser : System.Web.UI.Page{protected System.Web.UI.WebControls.Button Button1;protected System.Web.UI.WebControls.Button Button2;public RandomNum SessionID; private void Page_Load(object sender, System.EventArgs e){Common dai=new Common();//session("verifycode")=rndnum//Response.Write(SessionID.Text.ToString());this.Button1.Click += new System.EventHandler(OnPluginClick);}public delegate void PerformInsert(string plugname,StringBuilder sql);private void OnPluginClick(object sender,EventArgs args){ StringBuilder sql=new StringBuilder(); sql.Append("insert into clubuser (ID,sessionID,username) values (2,'123123','fuck')");Common InsertUser=new Common();PerformInsert Insert=new PerformInsert(InsertUser.PerformInsert); Insert("clubstar.IPlug.DataOp.User",sql); //调用插件所代理的方法}#region Web 窗体设计器生成的代码override protected void OnInit(EventArgs e){//// CODEGEN: 该调用是 ASP.NET Web 窗体设计器所必需的。//InitializeComponent();base.OnInit(e);}/// /// 设计器支持所需的方法 - 不要使用代码编辑器修改/// 此方法的内容。/// private void InitializeComponent(){this.Button2.Click += new System.EventHandler(this.Button2_Click);this.Load += new System.EventHandler(this.Page_Load);}#endregionprivate void Button2_Click(object sender, System.EventArgs e){}}}而上面文件中的PerformInsert代理针对如下事件函数进行操作using System;using System.Configuration;using clubstar.IPlug;using System.Text;using System.Data.OleDb;namespace clubstar{/// /// Common 的摘要说明。/// public class Common{public Common(){}private PluginCollection m_plugins = null; //被回调用于对插件进行插入操作public void PerformInsert(string plugname,StringBuilder sql) //执行插入操作{ m_plugins = (PluginCollection )ConfigurationSettings.GetConfig("IPlugs");PlugSqlOp context = new PlugSqlOp(sql.ToString());foreach(IPlugStarClub plugin in m_plugins){if(plugin.Name==plugname){plugin.PerformInsert(context);return ;}}}public void PerformDelete(string plugname,StringBuilder sql)//执行删除操作{m_plugins = (PluginCollection )ConfigurationSettings.GetConfig("IPlugs");PlugSqlOp context = new PlugSqlOp(sql.ToString());foreach(IPlugStarClub plugin in m_plugins){if(plugin.Name==plugname){plugin.PerformDelete(context);return ;}}}public void PerformUpdate(string plugname,StringBuilder sql)//执行更新操作{m_plugins = (PluginCollection )ConfigurationSettings.GetConfig("IPlugs");PlugSqlOp context = new PlugSqlOp(sql.ToString());foreach(IPlugStarClub plugin in m_plugins){if(plugin.Name==plugname){plugin.PerformUpdate(context);return ;}}}private OleDbDataReader dr;public OleDbDataReader PerformSelect(string plugname,StringBuilder sql)//执行查询操作{//OleDbDataReader dr=new OleDbDataReader();m_plugins = (PluginCollection )ConfigurationSettings.GetConfig("IPlugs");PlugSqlOp context = new PlugSqlOp(sql.ToString());foreach(IPlugStarClub plugin in m_plugins){if(plugin.Name==plugname){dr=plugin.PerformSelect(context);return dr;}}return dr;}//如何使用上面的功能:先在前端文件中生成如下代理://public delegate void PerformInsert(string plugname,StringBuilder sql);//public delegate void PerformDelete(string plugname,StringBuilder sql);//public delegate OleDbDataReader PerformSelect(string plugname,StringBuilder sql);//public delegate void PerformUpdate(string plugname,StringBuilder sql);/* 插入示例StringBuilder sql=new StringBuilder();sql.Append("insert into clubuser (ID,sessionID,username) values (2,'123123','fuck')");Common InsertUser=new Common();PerformInsert Insert=new PerformInsert(InsertUser.PerformInsert);Insert("clubstar.IPlug.DataOp.User",sql); //调用插件所代理的方法*//* 删除示例StringBuilder sql=new StringBuilder();sql.Append("delete from clubuser where ID=2");Common DeleteUser=new Common();PerformDelete Delete=new PerformDelete(DeleteUser.PerformDelete);Delete("clubstar.IPlug.DataOp.User",sql); //调用插件所代理的方法*//* 查询示例StringBuilder sql=new StringBuilder();sql.Append("select * from clubuser where ID=2");Common SelectUser=new Common();PerformSelect Select=new PerformSelect(SelectUser.PerformSelect);dr=Select("clubstar.IPlug.DataOp.User",sql); //调用插件所代理的方法do{ Response.Write(dr["username"].ToString()+""); Response.Write(dr["nickname"].ToString()+"");}while(dr.Read());*//* 更新示例StringBuilder sql=new StringBuilder();sql.Append("update clubuser set ID=3 where ID=2");Common UpdateUser=new Common();PerformUpdate Update=new PerformUpdate(UpdateUser.PerformUpdate);Update("clubstar.IPlug.DataOp.User",sql); //调用插件所代理的方法*/}}最后，只需要在WEBCONFIG中写入插件的信息就可以调用前面所写的插件了：<?xml version="1.0" encoding="utf-8" ?> .........由于这是本人第一次写文章，加之时间仓促，望各个大侠见谅。关闭本页
