你好，
是的，至少在我这边，非双工通信的模式下，在服务端关闭了情况下，重启服务端，客户端仍然可以正常调用服务端的服务。
我这里写一个例子，你可以参看下。
Server(Console application)
class Program
{
static void Main(string[] args)
{
using (ServiceHost sh=new ServiceHost(typeof(MyService)))
{
sh.Open();
Console.WriteLine("serivce is ready....");
Console.ReadLine();
sh.Close();
}
}
}
[ServiceContract]
public interface IService
{
[OperationContract]
string SayHello();
}
public class MyService : IService
{
public string SayHello()
{
return DateTime.Now.ToShortTimeString();
}
}
Appconfig(Server).
<system.serviceModel>
<services>
<service name="VM1.MyService" behaviorConfiguration="mybehavior">
<endpoint address="" binding="basicHttpBinding" contract="VM1.IService"></endpoint>
<endpoint address="mex" binding="mexHttpBinding" contract="IMetadataExchange"></endpoint>
<host>
<baseAddresses>
<add baseAddress="http://localhost:6300/"/>
</baseAddresses>
</host>
</service>
</services>
<behaviors>
<serviceBehaviors>
<behavior name="mybehavior">
<serviceMetadata/>
</behavior>
</serviceBehaviors>
</behaviors>
</system.serviceModel>
Client(Console application,invoke the service by adding service reference).
static void Main(string[] args)
{
ServiceReference2.ServiceClient client = new ServiceReference2.ServiceClient();
Console.WriteLine(client.SayHello());
Console.WriteLine(client.State);
Console.WriteLine("请关闭服务端");
Console.ReadLine();
try
{
Console.WriteLine(client.SayHello());
}
catch (Exception)
{
Console.WriteLine("调用失败");
}
Console.WriteLine("请重启服务端");
Console.ReadLine();
Console.WriteLine(client.SayHello());
Console.ReadLine();
}
客户端Appconfig(auto-generated),需要根据实际情况修改终结点为服务器地址，同一台机器上，Localhost就可以了。
<system.serviceModel>
<bindings>
<basicHttpBinding>
<binding name="BasicHttpBinding_IService1" />
</basicHttpBinding>
</bindings>
<client>
<endpoint address="http://10.157.13.69:6300/" binding="basicHttpBinding"
bindingConfiguration="BasicHttpBinding_IService1" contract="ServiceReference2.IService"
name="BasicHttpBinding_IService1" />
</client>
</system.serviceModel>
