我正在尝试连接到作为Windows服务托管的WCF服务。
WCF服务的端点位于:
net.tcp://localhost:9164/GettingStarted/
我可以正常启动服务。
但是,我现在正尝试通过控制台应用程序连接到它。
这是代码:
static void Main(string[] args)
{
// Step 1: Create a URI to serve as the base address.
Uri baseAddress = new Uri("net.tcp://localhost:9164/GettingStarted/");
// Step 2: Create a ServiceHost instance.
ServiceHost selfHost = new ServiceHost(typeof(CalculatorService), baseAddress);
try
{
// Step 3: Add a service endpoint.
selfHost.AddServiceEndpoint(typeof(ICalculator), new NetTcpBinding(), "CalculatorService");
// Step 4: Enable metadata exchange.
ServiceMetadataBehavior smb = new ServiceMetadataBehavior();
smb.HttpGetEnabled = false;
smb.HttpsGetEnabled = false;
selfHost.Description.Behaviors.Add(smb);
// Step 5: Start the service.
selfHost.Open();
Console.WriteLine("The service is ready.");
// Close the ServiceHost to stop the service.
Console.WriteLine("Press <Enter> to terminate the service.");
Console.WriteLine();
Console.ReadLine();
selfHost.Close();
}
catch (CommunicationException ce)
{
Console.WriteLine("An exception occurred: {0}", ce.Message);
selfHost.Abort();
}
}
运行此命令时,我不断收到此异常:
System.ServiceModel.AddressAlreadyInUseException
但是,没有其他东西连接到该服务。
此外,当基于http的时候,我可以通过Web浏览器测试该服务。如何使用net.tcp进行测试?
编辑:
WCF客户端更新:
static void Main(string[] args)
{
ChannelFactory<ICalculator> channelFactory = null;
try
{
NetTcpBinding binding = new NetTcpBinding();
EndpointAddress endpointAddress = new EndpointAddress("net.tcp://localhost:9164/GettingStarted/CalculatorService");
channelFactory = new ChannelFactory<ICalculator>(binding, endpointAddress);
ICalculator channel = channelFactory.CreateChannel();
double result = channel.Add(4.0, 5.9);
}
catch (TimeoutException)
{
//Timeout error
if (channelFactory != null)
channelFactory.Abort();
throw;
}
catch (FaultException)
{
if (channelFactory != null)
channelFactory.Abort();
throw;
}
catch (CommunicationException)
{
//Communication error
if (channelFactory != null)
channelFactory.Abort();
throw;
}
catch (Exception)
{
if (channelFactory != null)
channelFactory.Abort();
throw;
}
}

根据您的描述,您的WCF服务已托管在Windows服务上。现在,您想连接到它。我不明白连接的含义。由于WCF服务托管在Windows服务上,因此您可以根据WCF服务生成一个代理类来调用它,但是我发现您的控制台应用程序仍然希望托管WCF服务。我不知道要做什么,但是如果要在控制台应用程序中托管WCF服务,则需要更改基地址,因为根据您的描述,您需要在Windows服务和控制台应用程序中托管WCF服务。但是它们的地址不能相同,您可以在控制台应用程序中更改基址,例如:
Uri baseAddress = new Uri("net.tcp://localhost:9166/Test/");
ServiceHost selfHost = new ServiceHost(typeof(Service1), baseAddress);
