SilverLight 初探一_app

概述今天是本人初次接触银光，以前只听说银光何其的牛叉，却一直没有机会学习。今天恰好有时间，也趁公司机子上装的是VS2010。说到这个，我就来气，我的dell 1420装不上VS2010。今天呢，本人就来个银光的数据CURD例子。别人爱说CURD，我也用这个，初次看见这个我还懵了一下，什么事CURD，原来是Create，Update，Read，Delete。废话不多说，来个现实的例子。先新建一个Silv

今天是本人初次接触银光，以前只听说银光何其的牛叉，却一直没有机会学习。今天恰好有时间，也趁公司机子上装的是VS2010。说到这个，我就来气，我的dell 1420装不上VS2010。今天呢，本人就来个银光的数据CURD例子。别人爱说CURD，我也用这个，初次看见这个我还懵了一下，什么事CURD，原来是Create，Update，Read，Delete。废话不多说，来个现实的例子。先新建一个Silverlight Application。

选择Silverlight Application。ok项目建好了，我们再建一个WCF Service Application以及一个Entity Data Model，如下

我们先来写这个WCF服务，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;      using System.Data;      using Model;      namespace DataProvIDer      {          // NOTE: You can use the "Rename" command on the "Refactor" menu to change the class name "Service1" in code, svc and config file together.          public class Service1 : IService1          {              DataEntitIEs dataEntitIEs = new DataEntitIEs();                   /// <summary>              /// 获取实体              /// </summary>              /// <param name="value">主键</param>              /// <returns></returns>              public List<SS_ORGA> GetData()              {                  List<SS_ORGA> ssOrgaList = dataEntitIEs.SS_ORGA.ToList();                  return ssOrgaList;              }                   /// <summary>              /// 删除数据              /// </summary>              /// <param name="ID">主键</param>              public voID DeleteData(string ID)              {                  SS_ORGA ssOrga = dataEntitIEs.SS_ORGA.SingleOrDefault(s => s.C_ORGA_ID == ID);                  dataEntitIEs.SS_ORGA.DeleteObject(ssOrga);                  dataEntitIEs.SaveChanges();              }                   /// <summary>              /// 修改数据              /// </summary>              /// <param name="ssOrga">要修改的实体对象</param>              public voID ModifyData(SS_ORGA ssOrga)              {                  dataEntitIEs.ApplyCurrentValues("SS_ORGA", ssOrga);                  dataEntitIEs.SaveChanges();              }                   /// <summary>              /// 添加数据              /// </summary>              /// <param name="ssOrga">要添加的实体对象</param>              public voID AddData(SS_ORGA ssOrga)              {                  dataEntitIEs.AddToSS_ORGA(ssOrga);                  dataEntitIEs.SaveChanges();              }          }      }    @H_960_404@

ok，WCF写完了，我们再来将它引用到Silverlight项目中。在DataManage项目的References上点击右键，选择Add Service Reference。d出以下界面，我们点击discover，找到了我们刚才写的WCF服务，我们把nameSpace改为MyService。

引用完了，我们把WCF服务发布到IIS服务器，这里我们用的端口是1933。这个发布我就不多说了，大家都会。看看Silverlight服务引用客户端配置，如下

  <configuration>         <system.serviceModel>             <bindings>                 <basichttpBinding>                     <binding name="BasichttpBinding_IService1" maxBufferSize="2147483647"                         maxReceivedMessageSize="2147483647">                         <security mode="None" />                     </binding>                 </basichttpBinding>             </bindings>             <clIEnt>                 <endpoint address="http://localhost:1993/Service1.svc" binding="basichttpBinding"                     bindingConfiguration="BasichttpBinding_IService1" contract="MyService.IService1"                     name="BasichttpBinding_IService1" />             </clIEnt>         </system.serviceModel>     </configuration>   @H_960_404@

ok，我们再看看，WPF端的调用，这里我们只做一个例子，就做个删除吧。先看看前台代码

再看看后台代码
