c# - how to convert a ultraQRCodeBarcode1 infragistic Winforms control into image -

i've got qr control generating qr code , when scan phone works perfectly. i'm not able convert image can save database. i've looked on website , can't find anything, have wpf or web nothing on winforms. here how generate qr code

private void btngenerate_click(object sender, eventargs e)     {         string data = string.empty;         var fullname = txtfirstname + " " + txtmiddlename + " " + txtlastname;         if (!string.isnullorempty(txtlicencenumber.text))         {             data = fullname;             data += ", " + environment.newline + txtdistrict.text;             data += ", " + environment.newline + txtlicencenumber.text;             data += ", " + environment.newline + txtregistrationcode;         }         ultraqrcodebarcode1.data = data;     } 

and save method i'm trying convert byte code , save i'm not successful there no property image in one.

 user.qrcode = imagetobytearray(ultraqrcodebarcode1.); 

image converter

 private byte[] imagetobytearray(string imagepath)     {         byte[] data = null;         var fileinfo = new fileinfo(imagepath);         long numbytes = fileinfo.length;         var filestream = new filestream(imagepath, filemode.open, fileaccess.read);         var binaryreader = new binaryreader(filestream);         data = binaryreader.readbytes((int)numbytes);         return data;     } 

ultraqrcodebarcode has saveto method. method has several overloads allowing save qr code image or memory stream. in case create memory stream , convert stream byte array this:

byte[] data; using(memorystream ms = new memorystream()) {     this.ultraqrcodebarcode1.saveto(ms, imageformat.png);     byte[] data = ms.toarray(); }
