I just want the same functionality (take a URL and convert it to base64) but more effecicnt and takes less time because I am dealing with many images and populating a gridview. stringbuilder _sb = new stringbuilder (); //create a byte array that will hold the return value of the getimg method byte [] _byte = this.getimg (url); //appends the argument to the stringbulilder object (_sb) _sb.append (convert.tobase64string (_byte, 0, _byte.length)); //return the complete and final url in a base64 format. We are not comfortable displaying the url in the source code.
