如何根据其ActionResult类型处理控制器动作？

public ActionResult(int audioId)
{
    byte[] bytes = getAudio(audioId);
    if (bytes != null) 
    {
        return new FileContentResult(bytes, \"audio/wav\");
    }
    else
    {
        return Json(new { success = false });
    }
}

$.get(\'PLACE_URL_HERE\', function (data, status, jqXHR) {
    var type = jqXHR.getResponseHeader(\'Content-Type\');

    if (type === \'application/json\')
    {
        // Show warning
    }
    else if (type == \'audio/wav\')
    {
        // Open new window
    }
});
