WCF - 这可能是由于服务端点绑定不使用HTTP协议 [英] WCF - This could be due to the service endpoint binding not using the HTTP protocol

问题描述

大家好，



我正在从我的WCF服务中获取异常，返回类型为object []的方法。



异常



收到http：// gcotdvm3722126的HTTP响应时出错/CAT.NextGenService/NextGenService.svc。这可能是由于服务端点绑定不使用HTTP协议。这也可能是由于服务器中止HTTP请求上下文（可能是由于服务关闭）。有关详细信息，请参阅服务器日志。



参考点。

1.我已托管我在IIS中的WCF服务并从WPF应用程序调用它。

2.我可以调试并从返回类型为string和int的所有方法中获取结果，除非使用object []作为返回的方法类型。



对象[] MyMethod（字符串foo1，字符串foo2）

3.我也可以调试上面的方法，点击服务并从我的数据访问层获取结果，但是在之后的上述异常中它会中断。



服务器配置文件

Hi All,

I am getting following exception from the my WCF service one for the method with return type object[].

Exception

An error occurred while receiving the HTTP response to http://gcotdvm3722126/CAT.NextGenService/NextGenService.svc. This could be due to the service endpoint binding not using the HTTP protocol. This could also be due to an HTTP request context being aborted by the server (possibly due to the service shutting down). See server logs for more details.

Reference Points.
1. I have hosted my WCF service in IIS and calling it from a WPF application.
2. I could debug and get result from all the methods with return type string and int except with the method with object[] as the return type.

object [] MyMethod(string foo1, string foo2)
3. I could also debug the above method, hit the service and get results from my data access layer but it breaks after that with the aforementioned exception.
