问题描述
我是否需要在使用 ConcurrencyMode.Multiple 和 InstanceContextMode.PerCall 或 InstanceContextMode.PerSession 的 WCF 服务中实现自己的锁定?由于在每次调用或新会话时都会创建一个新的 ServiceContext 对象，我应该认为我不会，但我不确定.
Do I need to implement my own locking in a WCF service that uses ConcurrencyMode.Multiple and InstanceContextMode.PerCall or InstanceContextMode.PerSession? Since a new ServiceContext object is created at every call or new session I should think that I would not, but I'm far from sure.
示例:
[ServiceBehavior(ConcurrencyMode = ConcurrencyMode.Multiple, InstanceContextMode = InstanceContextMode.PerSession,
IncludeExceptionDetailInFaults = false, MaxItemsInObjectGraph = Int32.MaxValue)]
public class ExampleService : IExample
推荐答案
不，您不必添加锁定.每次调用都会获得一个新实例.
No you don't have to add locking. Each call will get a fresh instance.
但是，如果您需要来自特定调用者的状态，则必须手动处理.
However, if you need state from a particular caller, that will have to be handled manually.
