请求一个action，将图片的二进制字节字符串在视图页面以图片形式输出

有些时候需要将二进制图片字节在发送浏览器以图片形式显示：

下面是一些示例代码：

控制器：

    /// <summary>
    /// 将图片的二进制字节字符串在视图页面以图片形式输出
    /// </summary>
    public class HomeController : Controller
    {

        public ActionResult Test()
        {
            return View();
        }

        //方法一：
        public FileResult TestFileResult_1()
        {
            byte[] mybyte;
            using (WebClient client = new WebClient())
            {
                mybyte = client.DownloadData("http://img.baidu.com/video/img/video_logo_new.gif");
                MemoryStream ms = new MemoryStream(mybyte);
                //System.Drawing.Image img;
                //img = System.Drawing.Image.FromStream(ms); 
            }
            return File(mybyte, "image/gif");
        }

        //方法二：
        public FileResult TestFileResult()
        {
            byte[] mybyte;
            using (WebClient client = new WebClient())
            {
                mybyte = client.DownloadData("http://img.baidu.com/video/img/video_logo_new.gif");
                MemoryStream ms = new MemoryStream(mybyte);
                //System.Drawing.Image img;
                //img = System.Drawing.Image.FromStream(ms); 
            }
            return new FileContentResult(mybyte, "image/gif");
        }

        //方法三：
        public ActionResult TestFileContentResult()
        {
            byte[] mybyte;
            using (WebClient client = new WebClient())
            {
                mybyte = client.DownloadData("http://img.baidu.com/video/img/video_logo_new.gif");
                MemoryStream ms = new MemoryStream(mybyte);
            }
            return new FileContentResult(mybyte, "image/gif");
        }

        //方法四：
        public ActionResult TestFile()
        {
            byte[] mybyte;
            using (WebClient client = new WebClient())
            {
                mybyte = client.DownloadData("http://img.baidu.com/video/img/video_logo_new.gif");
                //MemoryStream ms = new MemoryStream(mybyte);
                //System.Drawing.Image img;
                // img = System.Drawing.Image.FromStream(ms);
            }
            return File(mybyte, "image/gif");
        }




        public ActionResult Index()
        {
            return View();
        }
    }

视图（view）：

@{
    ViewBag.Title = "Test";
    Layout = "~/Views/Shared/_Layout.cshtml";
}

TestFile:<img src="@(Url.Action("TestFile", "Home"))"/>
<br/>
<br/>
TestFileContentResult:<img src="@(Url.Action("TestFileContentResult", "Home"))"/>

<br/>
<br/>
TestFileResult:<img src="@(Url.Action("TestFileResult", "Home"))"/>

<br/>
<br/>
TestFileResult:<img src="@(Url.Action("TestFileResult_1", "Home"))"/>

运行结果如下图所示：
