SilverLight 初探

先新建一個Silverlight Application。express

選擇Silverlight Application。ok項目建好了，咱們再建一個WCF Service Application以及一個Entity Data Model，以下服務器

咱們先來寫這個WCF服務，代碼以下微信

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>
/// 獲取實體
/// </summary>
/// <param name="value">主鍵</param>
/// <returns></returns>
public List<SS_ORGA> GetData()
{
List<SS_ORGA> ssOrgaList = dataEntities.SS_ORGA.ToList();
return ssOrgaList;
}
/// <summary>
/// 刪除數據
/// </summary>
/// <param name="id">主鍵</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>
/// 修改數據
/// </summary>
/// <param name="ssOrga">要修改的實體對象</param>
public void ModifyData(SS_ORGA ssOrga)
{
dataEntities.ApplyCurrentValues("SS_ORGA", ssOrga);
dataEntities.SaveChanges();
}
/// <summary>
/// 添加數據
/// </summary>
/// <param name="ssOrga">要添加的實體對象</param>
public void AddData(SS_ORGA ssOrga)
{
dataEntities.AddToSS_ORGA(ssOrga);
dataEntities.SaveChanges();
}
}
}

ok，WCF寫完了，咱們再來將它引用到Silverlight項目中。在DataManage項目的References上點擊右鍵，選擇Add Service Reference。彈出如下界面，咱們點擊Discover，找到了咱們剛纔寫的WCF服務，咱們把NameSpace改成MyService。ide

引用完了，咱們把WCF服務發佈到IIS服務器，這裏咱們用的端口是1933。這個發佈我就很少說了，你們都會。看看Silverlight服務引用客戶端配置，以下學習

<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>

ok，咱們再看看，WPF端的調用，這裏咱們只作一個例子，就作個刪除吧。先看看前臺代碼this

<UserControl x:Class="DataManage.MainPage"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"

<Grid x:Name="LayoutRoot" Background="White" Width="665">
<data:DataGrid Height="200" AutoGenerateColumns="False" HorizontalAlignment="Left" Margin="65,62,0,0" Name="dataGrid1" VerticalAlignment="Top" Width="524" Background="#FFA0AC9E" Foreground="#FF1010FA">
<data:DataGrid.Columns>
<data:DataGridTemplateColumn Header="請選擇" >
<data:DataGridTemplateColumn.CellTemplate>
<DataTemplate>
<RadioButton Content="" Height="16" HorizontalAlignment="Center" Margin="0,0,0,0" Name="radioButton1" VerticalAlignment="Center" />
</DataTemplate>
</data:DataGridTemplateColumn.CellTemplate>
</data:DataGridTemplateColumn>
<data:DataGridTextColumn Header="部門Id" Binding="{Binding C_ORGA_ID}"></data:DataGridTextColumn>
<data:DataGridTextColumn Header="部門名稱" Binding="{Binding C_ORGA_NM}"></data:DataGridTextColumn>
<data:DataGridTextColumn Header="部門類型" Binding="{Binding C_ORGA_TP}"></data:DataGridTextColumn>
<data:DataGridTextColumn Header="電話" Binding="{Binding C_PHONE}"></data:DataGridTextColumn>
<data:DataGridTextColumn Header="部門描述" Binding="{Binding C_ORGA_DESC}"></data:DataGridTextColumn>
<data:DataGridTextColumn Header="電子郵箱" Binding="{Binding C_EMAIL}"></data:DataGridTextColumn>
</data:DataGrid.Columns>
</data:DataGrid>
<Button Content="刪除" Height="23" HorizontalAlignment="Left" Margin="446,33,0,0" Name="button1" VerticalAlignment="Top" Width="75" Click="button1_Click" />
</Grid>
</UserControl>

再看看後臺代碼spa

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 System.Net.Browser;
namespace DataManage
{
using MyService;
public partial class MainPage : UserControl
{
public MainPage()
{
InitializeComponent();
/*404 not found 加入如下代碼*/
bool registerResult = WebRequest.RegisterPrefix("http://", WebRequestCreator.ClientHttp);
bool httpsResult = WebRequest.RegisterPrefix("https://", WebRequestCreator.ClientHttp);
}
/// <summary>
/// 刪除數據
/// </summary>
/// <param name="sender"></param>
/// <param name="e"></param>
private void button1_Click(object sender, RoutedEventArgs e)
{
MyService.Service1Client client1 = new Service1Client();
client1.DeleteDataCompleted += new EventHandler<System.ComponentModel.AsyncCompletedEventArgs>(ClientDeleteDataCompleted);
client1.DeleteDataAsync(((SS_ORGA)dataGrid1.SelectedItem).C_ORGA_ID);
UserControl_Loaded(sender,e);
}
private void UserControl_Loaded(object sender, RoutedEventArgs e)
{
Brush br=new SolidColorBrush(Color.FromArgb(10,255,0,0));
dataGrid1.RowBackground = br;
dataGrid1.SelectionMode = DataGridSelectionMode.Single;
MyService.Service1Client client1 = new Service1Client();
client1.GetDataCompleted += new EventHandler<GetDataCompletedEventArgs>(ClientGetDataCompleted);
client1.GetDataAsync();
}
void ClientGetDataCompleted(object sender, GetDataCompletedEventArgs e)
{
if (e.Error == null)
{
this.dataGrid1.ItemsSource = e.Result;
}
else
{
MessageBox.Show(e.Error.Message);
}
}
void ClientDeleteDataCompleted(object sender, System.ComponentModel.AsyncCompletedEventArgs e)
{
if (e.Error == null)
{
MessageBox.Show("刪除成功", "提示", MessageBoxButton.OK);
}
else
{
MessageBox.Show("刪除失敗", "提示", MessageBoxButton.OK);
}
}
}
}
