WCF Demo – Http、TCP Host

using System.Runtime.Serialization;
using System.ServiceModel;
namespace PublicElements
{
public class publicData
{
[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; }
}
}
}
}
契约接口：
using System.Runtime.Serialization;
using System.ServiceModel;
namespace PublicElements
{
public class publicInterface
{
[ServiceContract]
public interface IService
{
[OperationContract]
string GetData(int value);
[OperationContract]
publicData.CompositeType GetDataUsingDataContract(publicData.CompositeType composite);
}
}
}
服务逻辑类：
namespace WCFService
{
[ServiceBehavior(InstanceContextMode = InstanceContextMode.Single)]
public class Service : PublicElements.publicInterface.IService
{
public string GetData(int value)
{
return string.Format("You entered: {0}", value);
}
public PublicElements.publicData.CompositeType GetDataUsingDataContract(PublicElements.publicData.CompositeType composite)
{
if (composite.BoolValue)
{
composite.StringValue += "Suffix";
}
return composite;
}
}
}
Host配置文件：
<?xmlversion="1.0"encoding="utf-8"?>
<configuration>
<!--配置监听的端口 -->
<appSettings>
<addkey="TcpService"value="net.tcp://localhost:9000/ServoceHost" />
<addkey="HttpService"value="http://localhost:9001/ServoceHost" />
</appSettings>
<system.serviceModel>
<services>
<!-- 服务配置-->
<servicebehaviorConfiguration="MyServiceTypeBehaviors"name="WCFService.Service">
<!— TCP 绑定 -->
<endpointaddress=""binding="netTcpBinding"bindingConfiguration=""
contract="PublicElements.publicInterface+IService" />
<!—Http绑定 -->
<endpointaddress=""binding="wsHttpBinding"bindingConfiguration=""
contract="PublicElements.publicInterface+IService" />
<!—为Http绑定公开元数据 -->
<endpointaddress="mex"binding="mexHttpBinding"
contract="PublicElements.publicInterface+IService" />
</service>
</services>
<!—配置服务器行为，公开http元数据 -->
<behaviors>
<serviceBehaviors>
<behaviorname="MyServiceTypeBehaviors" >
<serviceMetadatahttpGetEnabled="true" />
</behavior>
</serviceBehaviors>
</behaviors>
</system.serviceModel>
</configuration>
Host：
static void Main(string[] args)
{
#region使用配置文件的方法
Service WCFServer = new Service();
Uri tcpAddress = new Uri(ConfigurationManager.AppSettings["TcpService"]);
Uri httpAddress = new Uri(ConfigurationManager.AppSettings["HttpService"]);
ServiceHost serviceHost = new ServiceHost(WCFServer, tcpAddress, httpAddress);
serviceHost.Open();//
Console.WriteLine("服务器已经打开");
Console.WriteLine("按任意键关闭");
Console.Read();
serviceHost.Close();
#endregion
}
这样客户端就可以像WebService那样直接使用服务引用了。但是需要Host时正在运行可能接收到服务的元数据，因此需要添加服务引用必须在Host运行的时候添加引用。
