WCF服务连接 [英] WCF Service connection

问题描述

大家好

我创建了WCF服务，并通过UWP应用程序使用了它.我遇到一个问题，即有时客户端连接会在服务器完成返回之前就断开，从而导致数据不同步.如果客户端没有，我需要服务器回滚 完全接收返回对象.

I have created a WCF service and consumed it with a UWP app. I have an issue where at times the clients connection drops just before the server completes its return causing the data to get out of sync. I need to server to roll back if the client does not fully receive the return object.

我刚刚发现UWP现在支持System.Transaction，因此我无法将服务包装在事务范围中

I have just discovered that UWP does now support System.Transaction so I cannot wrap my service in transaction scope

我正在努力工作，但是受到阻碍，进度停滞了.

I am working on a work around but have be hindered and progress has stalled.

我的问题是:

1.客户端是否可以为每个调用(同一会话)使用相同的WCF服务器端对象?我注意到，每次对该服务的调用都会触发WCF构造函数.

1. is there a way for the Client to use the same WCF server side object for every call (same session)? I have noticed that every call to the service fires the WCF constructor.

和

2.当客户端将数据发送到服务并等待响应时，是否可以在服务器端测试客户端是否成功接收了响应.

2. when the client sends data to the service and is waiting for a response, is there a way to test on the server side that the client received the response successfully.

示例

公共字符串getname(){

public string getname(){

返回"Melinda"； <--当客户收到成功事件或失败事件时是否发生此类事件，或者失败

return "Melinda"; <---is there a success event or such when the client receives this, or a failure

}

谢谢

推荐答案

>>客户端是否可以为每个客户端使用相同的WCF服务器端对象通话(同一会话)?

>>is there a way for the Client to use the same WCF server side object for every call (same session)?

您可以尝试InstanceContextMode = InstanceContextMode.PerSession.但是WCF构造函数将被每次调用都调用.

You could try InstanceContextMode =InstanceContextMode.PerSession. But the WCF constructor will be called by every called.

您可以在下面的链接中获取有关InstanceContextMode = InstanceContextMode.PerSession的更多信息.

You could refer below link for more information about InstanceContextMode =InstanceContextMode.PerSession.

对于此问题，我认为您可以尝试双工，也可以尝试以下链接.

For this issue, I think you could try duplex, and you could try below link.

此外，如果您对第二个问题有任何疑问，我建议您发布一个新主题，然后我们可以将重点放在一个主题中.

In addition, if you have any issue for the second question, I would suggest you post a new thread, and then we could focus on the specific issue in one thread.
