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：
