How to catch ODataErrorException when I am making an OData call through HttpWebRequest in C#?

由 心已入冬 提交于 2020-01-16 15:57:07
问题 I am trying to call an OData service from my .Net console application using c#. I am using HttpWebRequest to make the call. Now if there is an OData specific error, for example, an invalid JSON payload, then an ODataErrorException is thrown from the OData server. My question is how to catch that ODataErrorException and extract the proper message out of it? The exception gets caught in WebException catch block, and it only shows me "400 Bad Request". But it doesn't show me the actual error

问题 We've introduced a few .NET pages into a Classic ASP application. When a user hits one of the .NET pages we use an HttpWebRequest to get session variable values from the ASP side by sending the request to a Class ASP page with the name of the session variable we want. This approach works, except in the following situation. On our production servers our IT folks have disabled the weak cipher algorithms with some registry hacking. We want to force 128 over 128 (or so I'm told by people who know

Should WebException.Response.GetResponseStream() be close / disposed?

由 别来无恙 提交于 2019-12-08 17:58:26
问题 When I catch a .NET WebException , should I close / dispose the Response.GetResponseStream() ? The MSDN example does not close or dispose anything in the exception. Many SO answers recommend disposing the response and / or the stream. I disposed the stream and this caused big problems. Because GetResponseStream() (always? / sometimes?) returns the same instance. So when I get the response stream and then dispose it, then maybe rethrow the exception to another layer that also gets the response

问题 I'm here because I have a problem while downloading some files through ftp protocol. It's weird because it occurs occasionally and even for the same single file.
