POUnable to Pass Image in HTTP POST in a HTTP Web Request in ASP.NET

Body
copied!<p>I am having trouble converting an image into bytes and saving it in database.</p> <p>Here is the description,</p> <p>I have an image that will be send from a remote device to the web server using HTTP POST.</p> <p>so what I am doing is I ask them to sent the image to me.</p> <p>Since the data is sent in POST i assume they will send me the Bytes by converting the bytes into string using </p> <p>byte[] img = FileUpload1.FileBytes; Encoding enc = Encoding.ASCII; string img = enc.GetString(img);</p> <p>Then they make a WebRequest using HTTPWebRequest and append this image in HTTP POST.</p> <p>The Whole Code for making the request ---</p> <pre><code> WebRequest request = WebRequest.Create(url); request.Method = "POST"; //Create the POST Data FileUpload img = (FileUpload)imgUpload; Byte[] imgByte = null; if (img.HasFile && img.PostedFile != null) { imgByte = imgUpload.FileBytes; } string imgPh = null; Encoding enc = Encoding.ASCII; if (imgByte != null) { imgPh = enc.GetString(imgByte); } string postData = "sid=8062BD53EB4552AD6D0FBB7E5DC5B7AF&status=Y&uid=123456789012&fname=Dinesh Singh&lname=Malik&ftname=Balwan&yrbirth=1988&gender=Male&address1=Address1&address2=Address2&address3=Address3&address4=Address4&imagePh=" + imgPh; byte[] post = Encoding.UTF8.GetBytes(postData); //Set the Content Type request.ContentType = "application/x-www-form-urlencoded"; request.ContentLength = post.Length; Stream reqdataStream = request.GetRequestStream(); // Write the data to the request stream. reqdataStream.Write(post, 0, post.Length); reqdataStream.Close(); // If required by the server, set the credentials. request.Credentials = CredentialCache.DefaultCredentials; WebResponse response = null; try { // Get the response. response = request.GetResponse(); } catch (Exception ex) { Response.Write("Error Occured."); } </code></pre> <p>On the Page to which Request is made I am getting this image again into bytes using</p> <pre><code> Encoding enc = Encoding.ASCII; byte[] imagePhoto = enc.GetBytes(postData["imageph"]); </code></pre> <p>From Here I save it into my Database</p> <p>But when I retrieve the image using the Handler, it does not show the image.</p> <hr> <p>The issue is the conversion of the image from byte[] to string and then converting string into byte[] at the Web Server. (Because when I save the image directly without this conversion using TestPage on server it shows the image.)</p> <p>So What am I doing wrong in this.</p> <p><strong>Also is there any way in the above code to get the data of HTTP Post as received by the Web Server (retrieve HTTP Headers).</strong> I want to retrieve this data received to sent it back to the Other Development to develop the request at the device in the same format as I am receiving in the HTTP Web Request URL</p> <p>Any help would be appreciated.</p>
