在raspberry pi上安装是单声道最新稳定版,使用.NET 4.5从服务器上的服务轮询数据。
我的服务器端配置:
<system.serviceModel>
<behaviors>
<serviceBehaviors>
<behavior name="vlcBehaviour">
<serviceMetadata httpGetEnabled="true" />
</behavior>
</serviceBehaviors>
</behaviors>
<services>
<service name="ser.Serwys">
<endpoint address="net.tcp://192.168.56.1:9070/WindowService" binding="netTcpBinding" bindingConfiguration="AnonymousTcpBinding"
contract="Window.Service.IWindowServiceHost" />
</service>
</services>
<bindings>
<netTcpBinding>
<binding name="AnonymousTcpBinding" receiveTimeout="00:00:01"
sendTimeout="00:00:01"
maxBufferSize="1000"
maxConnections="100"
maxBufferPoolSize="100"
listenBacklog="200"
maxReceivedMessageSize="1000">
<security mode="None" />
</binding>
</netTcpBinding>
</bindings>
</system.serviceModel>
在客户端:
<system.serviceModel>
<behaviors>
<endpointBehaviors>
<behavior name="maxItems">
<dataContractSerializer maxItemsInObjectGraph="2147483646" />
</behavior>
</endpointBehaviors>
</behaviors>
<bindings>
<netTcpBinding>
<binding name="AnonymousTcpBinding" openTimeout="00:00:01" receiveTimeout="00:00:01" sendTimeout="00:00:01" maxBufferSize="1000" maxConnections="200" listenBacklog="200" maxReceivedMessageSize="1000">
<security mode="None" />
</binding>
</netTcpBinding>
</bindings>
<client>
<endpoint name="WindowService" address="net.tcp://192.168.56.1:9070/WindowService" binding="netTcpBinding" bindingConfiguration="AnonymousTcpBinding" contract="Window.Service.IWindowServiceHost" />
</client>
</system.serviceModel>
服务合同:
namespace Window.Service
{
[ServiceContract(
Namespace = "http://window",
Name = "WindowHost")]
public interface IWindowServiceHost
{
[OperationContract]
void Connect(int windowId);
[OperationContract]
void Disconnect();
[OperationContract]
DisplayData GetData();
}
}
服务的实施:
[ServiceBehavior(InstanceContextMode = InstanceContextMode.Single, ConcurrencyMode = ConcurrencyMode.Single)]
public class Serwys:IWindowServiceHost
调用的方法:
public DisplayData GetData()
{
Console.WriteLine("Called get data {0}:{1}:{2}",DateTime.Now.Minute,DateTime.Now.Second,DateTime.Now.Millisecond);
return new DisplayData
{
BoxesInProgress = 1,
};
}
从客户端调用GetData需要花费越来越多的时间,不知道为什么。 我已经在Ubuntu上测试了它,Mono是最新版本,我如何记录它:
Stopwatch stp = new Stopwatch();
stp.Start();
var data = remote.GetData();
stp.Stop();
log.WarnFormat("Polling service took: {0} ms", stp.ElapsedMilliseconds);
任何解释?我认为这是Mono bug,因为设置是非常基本的,没有并发方法称为死简单,并且轮询时间正在增加。
我在计时器过去时调用它,为了测试我每隔10ms调用一次,但即使我每秒都调用它,它也在增长,但速度较慢,这只会让我在所有崩溃之前有更多的时间。
