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);
}
WinCE
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
