Question

I m trying to stream the response of my wcf dataservice to make waiting time more user friendly. The response is in XML format (I use entity framework 4.1) I have these predefined events

service.SendingRequest += service_SendingRequest;
service.ReadingEntity += service_ReadingEntity;
service.WritingEntity += service_WritingEntity;

之后,我称之为“数据服务”。

var items = myItems.Query.Execute();

这里是休庭事件。

        var response = (HttpWebResponse)e.Request.GetResponse();
        var resStream = response.GetResponseStream();

        var sb = new StringBuilder();
        var buf = new byte[1024];

        string tempString;
        int count;

        do
        {
            count = resStream.Read(buf, 0, buf.Length);

            if (count != 0)
            {
                tempString = Encoding.ASCII.GetString(buf, 0, count);
                sb.Append(tempString);
            }
        }
        while (count > 0);

So the problem is that after that nothing is happening. The next event ReadingEntity is not firing. How can I solve this issue?

您不能改变服务发出请求的方式。活动允许你修改你的要求,但服务机构必须自称。你的法典很可能打破了服务功能。我还认为,你努力做的是可能的。 WCF 数据服务处仍在内部使用周转基金,除非它使用流层,否则将总是等到整个电文传递到上层(正文)。只有在执行

你们试图做些什么,需要草率反应(在“世界合作框架”的流中使用)。由于存在违约的“世界合作框架”特征,加上草率反应,不属于你的控制范围。
