大家知道，SharePoint 2010支持客戶端的對(duì)象模型訪問(wèn)，主要有三種方式：

　　1..NET 的客戶端對(duì)象模型，2.Javascript 的客戶端對(duì)象模型 3.Silverlight的客戶端對(duì)象模型，這里就簡(jiǎn)單實(shí)現(xiàn)一個(gè)Silverlight的網(wǎng)頁(yè)計(jì)數(shù)器，來(lái)達(dá)到熟悉客戶端對(duì)象模型的目的。

　　其實(shí)這個(gè)簡(jiǎn)單的訪問(wèn)計(jì)數(shù)器主要就是統(tǒng)計(jì)了頁(yè)面刷新了多少次，邏輯很簡(jiǎn)單，當(dāng)頁(yè)面被load的時(shí)候，就將次數(shù)+1，將次數(shù)和頁(yè)面的地址作為一個(gè)Item存放在一個(gè)SharePoint list中。下面介紹具體的步驟：

　　1、準(zhǔn)備工作：在SharePoint 2010的某一個(gè)site下創(chuàng)建用來(lái)存放訪問(wèn)次數(shù)和頁(yè)面地址的list，我們可以取名為Hit Count list。

　　2、VS2010中創(chuàng)建Silverlight Application Project，然后添加客戶端對(duì)象模型的dll引用，在SharePoint2010中，Silverlight的支持客戶端對(duì)象模型的dll文件一般存放在c:/Program Files/Common Files/Microsoft Shared/Web Server Extensions/14/TEMPLATE/LAYOUTS/ClientBin下，所以我們?cè)陧?xiàng)目中先Add Reference，在上面的路徑下添加Microsoft.SharePoint.Client.Silverlight.dll 和 Microsoft.SharePoint.Client.Silverlight.Runtime.dll兩個(gè)dll。

　　3、在項(xiàng)目中添加一個(gè)Class，ClientOMProxy.cs作為silverlight訪問(wèn)SharePoint2010數(shù)據(jù)的代理類，因?yàn)镾ilverlight訪問(wèn)采用異步的方式，所以幾個(gè)基本的操作方法如下：

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Configuration;
using System.Xml;
using System.NET;
using Microsoft.SharePoint.Client;


namespace ADSK.AEC.SP2010.ClientOM
{
    public class ClientOMProxy:IDisposable
    {
        private ClientContext clientContext = null;
        public ListItemCollection listItems = null;
        public ClientOMProxy(string siteURL)
        {
            this.SiteURL = siteURL;
            clientContext = new ClientContext(this.SiteURL);
        }

        public  void GetListItemsAsync(string listName, string viewXML, out ListItemCollection listItems,  ClientRequestSucceededEventHandler successEventHandler, ClientRequestFailedEventHandler failEventHandler)
        {
            clientContext.Load(clientContext.Web);
            List targetList = clientContext.Web.Lists.GetByTitle(listName);
            clientContext.Load(targetList);
            CamlQuery camlQuery = new CamlQuery();
            camlQuery.ViewXml = viewXML;
            listItems = targetList.GetItems(camlQuery);
            clientContext.Load(listItems);
            clientContext.ExecuteQueryAsync(successEventHandler, failEventHandler);
        }

        public void CreateListItemAsync(string listName, Dictionary<string, object> fieldValueDic, ClientRequestSucceededEventHandler onSuccess, ClientRequestFailedEventHandler onFail)
        {
            clientContext.Load(clientContext.Web);
            List targetList = clientContext.Web.Lists.GetByTitle(listName);
            clientContext.Load(targetList);
            ListItemCreationInformation itemCreateInfo = new ListItemCreationInformation();
            ListItem oListItem = targetList.AddItem(itemCreateInfo);
            foreach (KeyValuePair<string, object> pair in fieldValueDic)
            {
                oListItem[pair.Key] = pair.Value;
            }
            oListItem.Update();
            clientContext.Load(oListItem);
            clientContext.ExecuteQueryAsync(onSuccess, onFail);
        }

        public void UpdateListItemAsync(string listName, ListItem item, Dictionary<string, object> fieldValueDic, ClientRequestSucceededEventHandler onSuccess, ClientRequestFailedEventHandler onFail)
        {
            clientContext.Load(clientContext.Web);
            List targetList = clientContext.Web.Lists.GetByTitle(listName);
            clientContext.Load(targetList);
            ListItem oListItem = item;
            foreach (KeyValuePair<string, object> pair in fieldValueDic)
            {
                oListItem[pair.Key] = pair.Value;
            }
            oListItem.Update();
            clientContext.Load(oListItem);
            clientContext.ExecuteQueryAsync(onSuccess, onFail);
        }

        public void Dispose()
        {
            if (null != clientContext)
                clientContext.Dispose();
        }
    }
}
