I have a WEB API in dotnet that returns a File

for example

  var fileResult = File(wavAudioBytes, "audio/mpeg");

then return it

 [HttpGet]
 public IActionResult Get()
 {
    
     var fileResult = File(wavAudioBytes, "audio/mpeg");

     return fileResult;
 }

I wanted to know if File contentType if there is a list or built in class that has all the supported list of contentTypes that File supports as its just a string and i don't know which ones it dose or dose not ? Specifically for audio files.

    That parameter ends up being the mime type header of the HTTP response, effectively just a string. It's use is to guide the browser on how to use the file, but nothing else. You can check the list of recognized mime types here: iana.org/assignments/media-types/media-types.xhtml Commented Feb 5 at 15:14

    One liner: var fileResult = File(wavAudioBytes, MimeMapping.GetMimeMapping("FileName")); Commented Feb 5 at 16:51
