我正在返回 HttpResponseMessage ，但是我的代码仍然抱怨并抛出错误，

I am returning HttpResponseMessage, but still my code complains and throw below error,

'TestController.Post()':并非所有代码路径都返回值

'TestController.Post()': not all code paths return a value

这里返回什么?

public async Task<IHttpActionResult> Post() { var response = await IsDataValid(); if (response) return Ok(new HttpResponseMessage(HttpStatusCode.OK)); }

推荐答案

您只需要再添加几行代码即可解决上述错误.

You need to add just few more line of code to deal with the above error.

public async Task<IHttpActionResult> Post() { var response = await IsDataValid(); if (response) return Ok(new HttpResponseMessage(HttpStatusCode.OK)); else return NotFound(); }

其他部分在这里很重要.

The else part is important here.
