MOSS关于EventHander编程

今天来给大家介绍关于EventHander的编程，在我们的实际MOSS的开发过程中，会遇到很多关于EventHander开发的需求，如，当我们在LIST里面创建一个ITEM的时候 ，我们希望做那些事情，监控那个LIST的时候，我们就可以用EventHander来做拉，在开发EventHander的时候，类库需要强命名，需要把开发的EventHandeR放到GAC里面，还要必须继承SPItemEventReceiver 类，这样就可以重在很多方法拉。那些方法 ，我相信大家看看就明白拉。下面是我测试的一个Demo！

using System;
using System.Collections.Generic;
using System.Text;
using Microsoft.SharePoint;

namespace LhEventHandlerConsole
{
    class Program
    {
        static void Main(string[] args)
        {
            SPSite site = new SPSite(@"http://lh-vmpc/personal/test/ShowJob");
            SPWeb web = site.OpenWeb();
            SPList list = web.Lists["SearchJob"];
            string Name = "LHEventHandler,Version=1.0.0.0,Culture=Neutral,PublicKeyToken=3c5da5cf700fd014,processorArchitecture=MSIL";
            string className = "LHEventHandler.ShowEventHandler";
            list.EventReceivers.Add(SPEventReceiverType.ItemAdding, Name, className);

            list.EventReceivers.Add(SPEventReceiverType.ItemAdded,Name,className);
            list.EventReceivers.Add(SPEventReceiverType.ItemUpdated, Name, className);
            list.EventReceivers.Add(SPEventReceiverType.ItemDeleting, Name, className);

           

            Console.WriteLine("It's OK");
            Console.ReadLine();
        }
    }
}



using System;
using System.Collections.Generic;
using System.Text;
using Microsoft.SharePoint;
namespace LHEventHandler
{
    class ShowEventHandler:SPItemEventReceiver
    {
        public override void ItemAdding(SPItemEventProperties properties)
        {
            //base.ItemAdding(properties);

            SPListItem item = properties.ListItem;
            string name = item["SearchResult"].ToString();
            string date = Convert.ToDateTime(item["SearchJobTime"]).ToShortDateString();
            item["标题"] = name + date+"AA";
            item.Update();

        }

        public override void ItemAdded(SPItemEventProperties properties)
        {
            //base.ItemAdded(properties);

            SPListItem item = properties.ListItem;
            string name = item["SearchResult"].ToString();
            string date = Convert.ToDateTime(item["SearchJobTime"]).ToShortDateString();
            item["标题"] = name+date;
            item.Update();

        }

        public override void ItemUpdated(SPItemEventProperties properties)
        {
            SPListItem item = properties.ListItem;
            string name = item["SearchResult"].ToString();
            string date = Convert.ToDateTime(item["SearchJobTime"]).ToShortDateString();
            item["标题"] = name + date;
            item.Update();

        }

        public override void ItemDeleting(SPItemEventProperties properties)
        {
            //base.ItemDeleting(properties);
            properties.ErrorMessage = "ShowGm say:~~~New no Delete Info!";
            properties.Cancel = true;
        }
    }
}
