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：
1 /// <summary> 2 /// 将图片的二进制字节字符串在视图页面以图片形式输出 3 /// </summary> 4 public class HomeController : Controller 5 { 6 7 public ActionResult Test() 8 { 9 return View(); 10 } 11 12 //方法一： 13 public FileResult TestFileResult_1() 14 { 15 byte[] mybyte; 16 using (WebClient client = new WebClient()) 17 { 18 mybyte = client.DownloadData("http://img.baidu.com/video/img/video_logo_new.gif"); 19 MemoryStream ms = new MemoryStream(mybyte); 20 //System.Drawing.Image img; 21 //img = System.Drawing.Image.FromStream(ms); 22 } 23 return File(mybyte, "image/gif"); 24 } 25 26 //方法二： 27 public FileResult TestFileResult() 28 { 29 byte[] mybyte; 30 using (WebClient client = new WebClient()) 31 { 32 mybyte = client.DownloadData("http://img.baidu.com/video/img/video_logo_new.gif"); 33 MemoryStream ms = new MemoryStream(mybyte); 34 //System.Drawing.Image img; 35 //img = System.Drawing.Image.FromStream(ms); 36 } 37 return new FileContentResult(mybyte, "image/gif"); 38 } 39 40 //方法三： 41 public ActionResult TestFileContentResult() 42 { 43 byte[] mybyte; 44 using (WebClient client = new WebClient()) 45 { 46 mybyte = client.DownloadData("http://img.baidu.com/video/img/video_logo_new.gif"); 47 MemoryStream ms = new MemoryStream(mybyte); 48 } 49 return new FileContentResult(mybyte, "image/gif"); 50 } 51 52 //方法四： 53 public ActionResult TestFile() 54 { 55 byte[] mybyte; 56 using (WebClient client = new WebClient()) 57 { 58 mybyte = client.DownloadData("http://img.baidu.com/video/img/video_logo_new.gif"); 59 //MemoryStream ms = new MemoryStream(mybyte); 60 //System.Drawing.Image img; 61 // img = System.Drawing.Image.FromStream(ms); 62 } 63 return File(mybyte, "image/gif"); 64 } 65 66 67 68 69 public ActionResult Index() 70 { 71 return View(); 72 } 73 }
视图（view）：
1 @{ 2 ViewBag.Title = "Test"; 3 Layout = "~/Views/Shared/_Layout.cshtml"; 4 } 5 6 TestFile:<img src="@(Url.Action("TestFile", "Home"))"/> 7 <br/> 8 <br/> 9 TestFileContentResult:<img src="@(Url.Action("TestFileContentResult", "Home"))"/> 10 11 <br/> 12 <br/> 13 TestFileResult:<img src="@(Url.Action("TestFileResult", "Home"))"/> 14 15 <br/> 16 <br/> 17 TestFileResult:<img src="@(Url.Action("TestFileResult_1", "Home"))"/>
运行结果如下图所示：
