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>
View Code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; } }
View CodexmlAdapter.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; } }
View Code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
