据我所知，ControllerBase 类中有辅助方法.只需使用 StatusCode 方法:

From what I can see there are helper methods inside the ControllerBase class. Just use the StatusCode method:

[HttpPost]
public IActionResult Post([FromBody] string something)
{    
    //...
    try
    {
        DoSomething();
    }
    catch(Exception e)
    {
         LogException(e);
         return StatusCode(500);
    }
}

您也可以使用 StatusCode(int statusCode, object value) 重载，它也可以协商内容.

You may also use the StatusCode(int statusCode, object value) overload which also negotiates the content.
