WinPhone7使用调用WCF传递对象

很少做手机开发,今天没事,做了个小小的实验,一般来讲,我学东西,只要能连上后台数据,基本上就可以了,因为前台很多东西要么不难,要么需要的是创意和美工,这都是我的薄弱之处,也就没兴趣深入了.

WCF大家估计都必须交熟悉,代码如下:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Runtime.Serialization;
using System.ServiceModel;
using System.ServiceModel.Web;
using System.Text;

namespace WcfService4
{
    // 注意: 使用“重构”菜单上的“重命名”命令，可以同时更改代码和配置文件中的接口名“IService1”。
    [ServiceContract]
    public interface IService1
    {

        [OperationContract]
        string GetData(int value);

        [OperationContract]
        CompositeType GetDataUsingDataContract(CompositeType composite);

        // TODO: 在此添加您的服务操作
    }


    // 使用下面示例中说明的数据约定将复合类型添加到服务操作。
    [DataContract]
    public class CompositeType
    {
        bool boolValue = true;
        string stringValue = "Hello ";

        [DataMember]
        public bool BoolValue
        {
            get { return boolValue; }
            set { boolValue = value; }
        }

        [DataMember]
        public string StringValue
        {
            get { return stringValue; }
            set { stringValue = value; }
        }
    }
}

直接在客户端添加服务引用,是一种方法,但这种方法有个问题,就是如果有复杂对象,就会出问题,没法生成服务所需要的代理代码.解决对象穿越问题,当然可以自己利用序列化和反序列化,中间利用字符串来传递,但这种方法工作量比较大.另外一种方式就是共享service服务接口和实体,这个非常方便,但问题是winphone和一般桌面的环境还是差很远,在wp7中引用实体解决还好点,要引用服务段的wcf契约接口问题很大,而且wp7里的servicemodel的版本和服务端的版本也不一致,调用也非常麻烦,最后找到一种利用silverlight的wcf ria service生成客户端代码工具来生成客户端代理得以解决,一般命令为:SlSvcUtil.exe 服务地址.把生成的文件引入到wp7工程即可用.生成的代码如下,其实大家可以学习它生成的代码,自己整一个通用的方法也是可行的:

调用奇简单:

        {
            BasicHttpBinding theBinding = new BasicHttpBinding();
            theBinding.MaxReceivedMessageSize = int.MaxValue;
            theBinding.MaxBufferSize = int.MaxValue;
            Service1Client theC = new Service1Client(theBinding, new EndpointAddress("http://localhost:1599/Service1.svc"));
            theC.GetDataCompleted += new EventHandler<GetDataCompletedEventArgs>(theC_GetDataCompleted);
            theC.GetDataUsingDataContractCompleted += new EventHandler<GetDataUsingDataContractCompletedEventArgs>(theC_GetDataUsingDataContractCompleted);
            theC.GetDataAsync(100);
            WcfService4.CompositeType theC1 = new WcfService4.CompositeType(){ StringValue="xxxxxx", BoolValue=true};
            theC.GetDataUsingDataContractAsync(theC1);
         
        }

        void theC_GetDataUsingDataContractCompleted(object sender, GetDataUsingDataContractCompletedEventArgs e)
        {
            this.listBox1.Items.Add(e.Result.StringValue);
        }

        void theC_GetDataCompleted(object sender, GetDataCompletedEventArgs e)
        {
            this.listBox1.Items.Add(e.Result);
        }

PS:wp7界面采用的也是wpf,所以很多绑定之类的技巧,也可以参考我前面的博文(silverlight,wpf).一个感觉就是wp7的学习成本对于微软体系的程序员来说很容易,这也是微软的强大之处,你只要学会了微软的这套东西,在手机,桌面,嵌入式,web端等开发之间进行转换很容易.
