Question

我一直在努力解决这个错误：

接收HTTP响应时发生错误 .... 8332 / Service1.svc。这可能是由于服务端点绑定不使用HTTP协议。这也可能是由于HTTP造成的请求上下文被服务器中止（可能是由于服务关闭）。有关详细信息，请参阅服务器日志。

我追踪了错误，显然它与绑定或连接有关，我无法弄清楚如何解决。 ..我正在把课程和配置文件放在下面。请提前指导我。谢谢。

Answer 1

您无法发送信息流。您需要通过在发送之前将其读取到结尾来实现您的流到实际数据对象（例如字符串或字节数组），或者如果您真的想要流式传输（我怀疑）您可以阅读this。 / p>

Answer 2

问题似乎是通过从类中删除流并单独返回来解决的！但我不知道它是如何帮助解决它的！
