微軟已在 .net compact framework 3.5版中加入了WCF client的功能(但並未支援WCF server)；
要在.net compact framework上使用wcf service必須用到Power Toys for .NET Compact Framework 3.5中的ServiceModel Metadata Tool for the .NET Compact Framework (NetCFSvcUtil)程式來產生Proxies藉以呼叫WCF service。
注意：若你是使用Windows 7以上的OS開發，務必下載支援windows 7的NetCFSvcUtil，否則無法正確產生proxies
以下說明如何建立service及client，
Server端：
Step 1: 新增合約IGreetingService.cs，此例之合約名稱為IGreetingService
namespace WcfDemoService
{
// 注意: 若變更此處的介面名稱 "IGreetingService"，也必須更新 App.config 中 "IGreetingService" 的參考。
[ServiceContract]
public interface IGreetingService
{
[OperationContract]
string DoWork();
}
}
Step 2:實作合約內容GreetingService.cs
namespace WcfDemoService
{
// 注意: 若變更此處的類別名稱 "GreetingService"，也必須更新 App.config 中 "GreetingService" 的參考。
public class GreetingService : IGreetingService
{
public string DoWork()
{
return "This is return string2";
}
}
}
Step 3: 在主程式中撰寫開啟服務的程式碼
class Program
{
static void Main(string[] args)
{
ServiceHost host = new ServiceHost(typeof(GreetingService));
try
{
host.Open();
Console.WriteLine("Server Opened !");
Console.Read();
}
finally
{
if (host.State == CommunicationState.Faulted)
host.Abort();
else
host.Close();
}
}
}
Step 4: 建立App.config
<?xml version="1.0" encoding="utf-8" ?>
<configuration>
<system.serviceModel>
<behaviors>
<serviceBehaviors>
<behavior name="WcfDemoService.GreetingServiceBehavior">
<serviceMetadata httpGetEnabled="true" />
<serviceDebug includeExceptionDetailInFaults="false" />
</behavior>
</serviceBehaviors>
</behaviors>
<services>
<service behaviorConfiguration="WcfDemoService.GreetingServiceBehavior"
name="WcfDemoService.GreetingService">
<endpoint address="GreetingService" binding="basicHttpBinding" contract="WcfDemoService.IGreetingService" bindingConfiguration="basicHttpBindingConfiguration">
<identity>
<dns value="localhost" />
</identity>
</endpoint>
<endpoint address="mex" binding="mexHttpBinding" contract="IMetadataExchange" />
<host>
<baseAddresses>
<add baseAddress="http://192.168.0.103:8731"/>
</baseAddresses>
</host>
</service>
</services>
<bindings>
<basicHttpBinding>
<binding name="basicHttpBindingConfiguration" maxReceivedMessageSize="20971510">
<readerQuotas maxStringContentLength="20971520" maxArrayLength="20971520"/>
</binding>
</basicHttpBinding>
</bindings>
</system.serviceModel>
</configuration>
Client端：
Step 1: 使用
NetCFSvcUtil產生Proxy檔案，方法如下：
a) 先執行host程式
b)在cmd下cd到NetCFSvcUtil.exe的路徑下，輸入NetCFSvcUtil.exe http://host ip:host port/ 按 下enter後會產生兩個檔案GreetingService.cs及CFClientBase.cs
Step 2:建立.net compact framework專案並匯入GreetingService.cs及CFClientBase.cs
Step 3: 在程式中撰寫呼叫wcf service的程式碼
private void btnGetStringByWCF_Click(object sender, EventArgs e)
{
System.ServiceModel.Channels.Binding binding =
GreetingServiceClient.CreateDefaultBinding();
string address = GreetingServiceClient.EndpointAddress.Uri.ToString();
GreetingServiceClient m_proxy =
new GreetingServiceClient(binding, new System.ServiceModel.EndpointAddress(address));
string GetString=m_proxy.DoWork();
this.textBox1.Text = GetString;
}
