MVP不仅避免了View和Model之前的耦合，更进一步地隆低了Presenter对View的依赖。View实现了接口IView。此处以一个微小的实例展示，废话不多说，直接上代码。

IView：

public interface IDisplayView    {        void DisplayInfo(IList
     
       blogs);        event EventHandler
      
        Commit;    }
      
     

Model：此处以BlogRepostory作为Model提供数据

public class BlogsRepostory    {        public static IList
     
       blogs = new List
      
       ();        public BlogsRepostory()        {                   }            }
      
     

Presenter:处理用户请求

public class BlogPresenter    {        public IDisplayView View { get; private set; }        public BlogPresenter(IDisplayView view)        {            this.View = view;            this.View.Commit += new EventHandler
     
      (Commit);        }        public void Initalize()        {                   }        protected void Commit(object sender,CommitEventArgs e)        {            BlogsRepostory.blogs.Add(e.blog);            this.View.DisplayInfo(BlogsRepostory.blogs);        }    }
     

在UI中实现了IView：

public partial class WebForm1 : System.Web.UI.Page, IDisplayView    {        public event EventHandler
     
       Commit;        public BlogPresenter Presenter { get; private set; }        public WebForm1()        {            this.Presenter = new BlogPresenter(this);        }        protected void Page_Load(object sender, EventArgs e)        {        }        public void DisplayInfo(IList
      
        blogs)        {            if (blogs != null && blogs.Count > 0)            {                var sb = new StringBuilder("
       
        ");                foreach (var blog in blogs)                {                    sb.AppendFormat("
", blog.Title, blog.Content);                }                sb.Append("
        
         
          
{0}
          
{1}
         
        
       
");                this.Lb_Info.Text = sb.ToString();            }        }        protected void Btn_Commit_Click(object sender, EventArgs e)        {            if (Commit != null)            {                Commit(this, new CommitEventArgs(new BlogInfo { Title = TB_Title.Text, Content = TB_Content.Text }));            }        }    }
      
     

功能看上去很简单，提交数据然后再显示出来。无非是把最肤浅的东西拿出来说一说，此模式的精妙之处还不甚了解，望各位高人指点一二，不胜感激......
