契约数据类：
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。
