Web API将HttpResponseMessage的描述返回到浏览器

Question

该代码应该导致文件下载...

public HttpResponseMessage Export()
{
    var byteArray = Encoding.UTF8.GetBytes("Hello World!");

    var stream = new MemoryStream(byteArray);

    var result = new HttpResponseMessage(HttpStatusCode.OK)
    {
        Content = new StreamContent(stream),
    };

    result.Content.Headers.ContentDisposition = new ContentDispositionHeaderValue("attachment")
    {
        FileName = "myFile.csv"
    };

    result.Content.Headers.ContentType = new MediaTypeHeaderValue("text/csv");

    return result;
}

相反，我收到此消息...

  

{“版本”：{“主要”：1，“次要”：1，“构建”：-1，“修订”：-1，“主要修订”：-1，“次要修订”：-1}， “ content”：{“ headers”：[]}，“ statusCode”：200，“ reasonPhrase”：“ OK”，“ headers”：[]，“ requestMessage”：null，“ isSuccessStatusCode”：true}

我在做什么错了？
