SilverLight学习笔记--WCF服务

编写WCF服务接口

using System;

using System.Collections.Generic;

using System.Linq;

using System.Runtime.Serialization;

using System.ServiceModel;

using System.Text;

namespace SilverlightApplication11.Web

{

// 注意: 如果更改此处的接口名称 "IMyWCFService"，也必须更新 Web.config 中对 "IMyWCFService" 的引用。

[ServiceContract]

public interface IMyWCFService

{

[OperationContract]

string ReturnXML();

}

编写服务类

using System;

using System.Collections.Generic;

using System.Linq;

using System.Runtime.Serialization;

using System.ServiceModel;

using System.Text;

namespace SilverlightApplication11.Web

{

// 注意: 如果更改此处的类名 "MyWCFService"，也必须更新 Web.config 中对 "MyWCFService" 的引用。

public class MyWCFService : IMyWCFService

{

public string ReturnXML()

{

string s;

s = @"<body IsMember='true'>

<form_LRB>

</form_LRB>

<head>

<form>

</form>

</head>

<base>

<NSRMC>东莞市愉达玻璃装饰工程有限公司</NSRMC>

</base>

</body>";

return s;

}

修改Web.config

特别注意一定要把binding 改为：basicHttpBinding，默认是wsHttpBinding，否则会出错提示“运行出错“System.ServiceModel.ProtocolException”

<system.serviceModel>

</behavior>

</serviceBehaviors>

</behaviors>

</identity>

</endpoint>

</service>

</services>

</system.serviceModel>

引用代理类

using System;

using System.Collections.Generic;

using System.Linq;

using System.Net;

using System.Windows;

using System.Windows.Controls;

using System.Windows.Documents;

using System.Windows.Input;

using System.Windows.Media;

using System.Windows.Media.Animation;

using System.Windows.Shapes;

using SilverlightApplication11.MyWCF;

using System.Xml;

using System.IO;

using System.ServiceModel.Channels;

using System.ServiceModel;

namespace SilverlightApplication11

{

public partial class Page : UserControl

{

public Page()

{

InitializeComponent();

GetService();

}

private void GetService()

{

Binding binding = new BasicHttpBinding();

EndpointAddress endPoint = new EndpointAddress("http://localhost:4162/MyWCFService.svc");

MyWCFServiceClient Mywcf = new MyWCFServiceClient(binding, endPoint);

Mywcf.ReturnXMLCompleted += new EventHandler<ReturnXMLCompletedEventArgs>(wcf_ReturnXMLCompleted);

Mywcf.ReturnXMLAsync();

}

void wcf_ReturnXMLCompleted(object sender, ReturnXMLCompletedEventArgs e)

{

if (e.Error == null)

{

using (XmlReader responseReader = XmlReader.Create(new StringReader(e.Result)))

{

responseReader.ReadToFollowing("YYSRBQ");

decimal YYSRBQ = responseReader.ReadElementContentAsDecimal();

responseReader.ReadToFollowing("YYCBBQ");

decimal YYCBBQ = responseReader.ReadElementContentAsDecimal();

responseReader.ReadToFollowing("YYLRBQ");

decimal YYLRBQ = responseReader.ReadElementContentAsDecimal();

responseReader.ReadToFollowing("instanceId");

string instanceId = responseReader.ReadInnerXml();

responseReader.ReadToFollowing("NSRMC");

string name = responseReader.ReadInnerXml();

OutputText.Text = "表单实例：" + instanceId + ""n" + name + ""n营业收入：" + YYSRBQ + ""n营业成本：" + YYCBBQ + ""n营业利润：" + YYLRBQ;

}
