Wince 中访问WCF服务

由于本文并非WinCE开发普及篇，所以一些WinCE开发和WCF开发的基础还请移步百度和谷歌寻找答案，然后结合本文开发出WinCE中如何访问WCF，谢谢。

开发环境

IDE：Visual Studio 2008 （2010、2012、2013目前都不支持）

OS：Win 7(64位)

Tools：ActiveSync Win7 v6.1（设备中心，给Pocket PC 2003模拟器提供网络）

模拟器网络连接攻略一份：http://www.jb51.net/softjc/42088.html

创建WinCE项目

请恕本文并非WinCE开发普及篇，所以这些请百度吧。

WCF服务端

app.config中关键代码

<service behaviorConfiguration="SystemDispatchServiceForPDABehavior" name="SystemManageServiceLibrary.SystemDispatchServiceForPDA">        <!--PDA系统分配-->        <endpoint address="http://localhost:20003/SystemDispatchForPDA/SystemDispatchServiceForPDA"          binding="webHttpBinding"          contract="SystemManageServiceLibrary.SystemDispatch.ISystemDispatchServiceForPDA" >        </endpoint>        <!--PDA系统分配元数据-->        <endpoint address="http://localhost:20003/SystemDispatchForPDA/SystemDispatchServiceForPDA/mex"          binding="mexHttpBinding" contract="IMetadataExchange" />        <host>          <baseAddresses>            <add baseAddress="http://localhost:20003/SystemDispatchForPDA"/>          </baseAddresses>          <timeouts openTimeout="00:00:30" />        </host>      </service>

服务契约 - 公布WCF REST（详细的可以百度搜索 WCF REST）

    [ServiceContract]    public interface ISystemDispatchServiceForPDA    {        /// <summary>        /// PDA获取集群信息        /// </summary>        /// <param name="strPDA_IMEI">PDA内部出厂序号</param>        /// <returns></returns>        [OperationContract]        //UriTemplate 实际就是通过http协议发送请求的url规则，把{strPDA_IMEI}替换成真实的PDA串号即可        [WebGet(UriTemplate = "GetClusterInfo/{strPDA_IMEI}")]        CLUSTER GetClusterInfo(string strPDA_IMEI);    }

HttpWrapper.cs - Http请求的封装，访问WCF提供的REST服务

    public class HttpWrapper    {        public static string SendRequest(string url)        {            HttpWebResponse response = null;            HttpWebRequest request = WebRequest.Create(url) as HttpWebRequest;            request.Method = "GET";            request.AllowWriteStreamBuffering = false;            request.KeepAlive = true;            request.ContentType = "application/x-www-form-urlencoded";            // 接收返回的页面            response = request.GetResponse() as HttpWebResponse;            Stream responseStream = response.GetResponseStream();            StreamReader reader = new System.IO.StreamReader(responseStream, Encoding.UTF8);            string strResult = reader.ReadToEnd();            reader.Close();            response.Close();            return strResult;        }    }

xmlAdapter.cs - Xml适配器，用于将Xml转换成类

    public class XmlAdapter    {        public static T ConvertToClass<T>(string strXML) where T : class        {            XmlSerializer xmlSerializer = new XmlSerializer(typeof(T));            MemoryStream reader = new MemoryStream(Encoding.UTF8.GetBytes(strXML));            T obj = xmlSerializer.Deserialize(reader) as T;            reader.Dispose();            return obj;        }    }

调用方法

        PRivate static string URL = "http://ip:20003/SystemDispatchForPDA/SystemDispatchServiceForPDA/";        public static CLUSTER GetClusterInfo(string strPDA_IMEI)        {            string strResponse = HttpWrapper.SendRequest(URL + "GetClusterInfo/" + strPDA_IMEI);            CLUSTER cluster = XmlAdapter.ConvertToClass<CLUSTER>(strResponse);            return cluster;        }

真正需要注意的其实就是几点：

1.安装设备中心

2.设置模拟器网络连接

3.WCF REST

4.WinCE解析WCF返回的XML，以及如何拼接访问的URL
