例如网上有这个相机：

http://cam-i.switch.ch/login.cgi?t=j&l=1&ch=2

它使用java。我想每隔 X 秒从相机中获取图像并将其显示在图片框上。

这是我试图使用的代码：

string sourceURL = "http://cam-i.switch.ch/login.cgi?t=j&l=1&ch=2";
            byte[] buffer = new byte[100000];
            int read, total = 0;
            // create HTTP request
            HttpWebRequest req = (HttpWebRequest)WebRequest.Create(sourceURL);
            req.Credentials = new NetworkCredential("username", "pass");
            // get response
            WebResponse resp = req.GetResponse();
            // get response stream
            Stream stream = resp.GetResponseStream();
            // read data from stream
            while ((read = stream.Read(buffer, total, 1000)) != 0)
            {
                total += read;
            }
            // get bitmap
            Bitmap bmp = (Bitmap)Bitmap.FromStream(
                          new MemoryStream(buffer, 0, total));

            pictureBox1.Image = bmp;

我在这一行得到 ArgumentException：

Bitmap bmp = (Bitmap)Bitmap.FromStream(
                          new MemoryStream(buffer, 0, total));

我看到缓冲区包含许多数字并且总数包含 15149 参数无效

我想让我输入的每个在线相机链接都能在pictureBox1上获得实时信息
