This is my webmethod to capture image by webcam.
- [WebMethod()]
- public static bool SaveCapturedImage(string data)
- {
- //string hostName = Dns.GetHostName();
- //string myIP = Dns.GetHostByName(hostName).AddressList[0].ToString();
- //myIP = HttpContext.Current.Request.ServerVariables["HTTP_X_FORWARDED_FOR"];
- //if (myIP == "" || myIP == null)
- //{

- //}
- // string fileName = myIP + DateTime.Now.ToString("dd-MM-yy_hh-mm");
- string fileName = DateTime.Now.ToString("dd-MM-yy_hh-mm");
- byte[] imageBytes = Convert.FromBase64String(data.Split(',')[1]);
- //Save the Byte Array as Image File.
- string filePath = HttpContext.Current.Server.MapPath(string.Format("~/CapturedImage/{0}.jpg", fileName));
- File.WriteAllBytes(filePath, imageBytes);
