If I am executing within the context of a particular service instance and operation, how do I get access to the currently-executing service instance? Service instances don't inherit from any specific common base class or interface and the only pathway into the existing context that I can find is:
如果我在特定服务实例和操作的上下文中执行,如何访问当前正在执行的服务实例?服务实例不从任何特定的公共基类或接口继承,并且我可以找到进入现有上下文的唯一途径:
OperationContext.Current
but I can't seem to find any properties that reference the actual service instance itself so that I can cast it to what I know it should be and perform operations on it.
但我似乎无法找到引用实际服务实例本身的任何属性,以便我可以将其转换为我应该知道的并对其执行操作。
Without exploring why I am doing this (it's irrelevant), please let me know if there is any way to find the reference I am looking for.
如果没有探究我为什么这样做(这是无关紧要的),请告诉我是否有任何方法可以找到我想要的参考。
EDIT:
[ServiceContract]
public interface IInventory
{
[OperationContract]
List<DealInfo> ListDeals(DealQueryOptions options);
}
// This is the object I will need access to the current instance of
public class Inventory : ServiceBase<Inventory>, IInventory
{
public List<DealInfo> ListDeals(DealQueryOptions options)
{
var obj = new Whatever(); // see below
}
}
public class Whatever
{
public Whatever()
{
// how do I get access to the service instance here?
// assume that in this context we are not allowed to
// pass the service instance to this class; this class
// must automatically discover the instance itself.
}
}

var myService = OperationContext.Current.InstanceContext.GetServiceInstance();

OperationContext.Current
should have a property for this IIRC
OperationContext.Current应具有此IIRC的属性
