How to stream with ASP.NET Core

Question

How to properly stream response in ASP.NET Core? There is a controller like this (UPDATED CODE):

[HttpGet(\"test\")]
public async Task GetT         


        

Answer 1

It is possible to return null or EmptyResult() (which are equivalent), even when previously writing to Response.Body. It may be useful if the method returns ActionResult to be able to use all the other results aswell (e.g. BadQuery()) easily.

[HttpGet("test")]
public ActionResult Test()
{
    Response.StatusCode = 200;
    Response.ContentType = "text/plain";
    using (var sw = new StreamWriter(Response.Body))
    {
        sw.Write("something");
    }
    return null;
}
