将动态生成的图像转换为 win 形式

Question

我正在尝试通过HttpWebRequest获取图像并以获胜形式显示它imagebox。通过 Fiddler ImageView 选项卡跟踪请求时，我可以看到可以正确查看图像，但在读取流时Stream was not readable我收到错误

Image img = Image.FromStream(stream). 

我错过了什么？

HttpWebRequest req =  HttpWebRequest request = (HttpWebRequest)WebRequest.Create("[URL here]");
HttpWebResponse response = (HttpWebResponse)req.GetResponse();    
Stream stream = response.GetResponseStream();
Image img = Image.FromStream(stream);   // ERROR occurs here
stream.Close();

经过一番挖掘，在这里找到了答案 C# gif 图像到内存流并返回（丢失动画）：

HttpWebRequest req =  HttpWebRequest request = (HttpWebRequest)WebRequest.Create("[URL here]");
HttpWebResponse response = (HttpWebResponse)req.GetResponse();    
Stream stream = response.GetResponseStream();
MemoryStream memoryStream = new MemoryStream();
stream.CopyTo(memoryStream);
memoryStream.Position = 0;
stream = memoryStream;
Image img = Image.FromStream(stream);   
stream.Close();
