带Stream的FileStreamResult mvc无法在Chrome中呈现图像

Question

我正在使用MemoryStream在站点外渲染某些图像。像\ renderProductprice.aspx？Pid = xxx。这将返回带有Stream和ContentType的FileStreamResult。

 private ActionResult GetPriceImage()
    {
        Image img = new Bitmap(100, 50);
        Graphics g = Graphics.FromImage(img);
        Font font = new Font("Arial", 24);
        PointF drawingPoint = new PointF(10, 10);
        g.DrawString("$Test Price", font, Brushes.Black, drawingPoint);

        MemoryStream ms = new MemoryStream();
        img.Save(ms, ImageFormat.Jpeg);

        ms.Position = 0;

        return new FileStreamResult(ms, "image/jpeg");
    }

这在除chrome（任何版本）之外的所有浏览器中均可正常显示。
