sharepoint中eventhandler的ItemUpdated
最近在开发Sharepoint的EventHandler的时候发现一个问题，更新事件的接受处理程序的特殊性，要被调用很多次，会达不到我们想要的效果，需要用 this.DisableEventFiring();来关闭事件监听器，在写完更新事件的代码之后要用this.EnableEventFiring();来开启事件监听器。这个我也是在网上找到的。using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.IO;
using Microsoft.SharePoint;
using Microsoft.SharePoint.Administration;
namespace CorpTrendEventDemo
{
public class IitemList : SPItemEventReceiver
{
public override void ItemUpdated(SPItemEventProperties properties)
{
SPListItem item = properties.ListItem;
SPWeb web = item.Web;
SPSite site = web.Site;
this.DisableEventFiring();
//修改审批状态
item["_ModerationStatus"] = (int)SPModerationStatusType.Approved;
item.Update();
item.CopyTo(properties.WebUrl + "/"+properties.OpenWeb().Lists["未发布动态"].RootFolder.Url+"/"+ item.Name);
item.Delete();
this.EnableEventFiring();
}
}
}
