Convert online image to base64 with C#

The following code will convert an online image to a base64 string.

The code was specifically written for use in LINQPad, hence the use of Dump().

String url = "http://ecx.images-amazon.com/images/I/51MVXV3QQ6L._SL500_SS150_.jpg";

Uri uri = new Uri(url);


WebClient client = new WebClient();
byte[] imageBytes = client.DownloadData(uri);


string base64String = Convert.ToBase64String(imageBytes);


base64String.Dump();


base64String.Length.Dump();
("<img src=‘data:image/jpg;base64," + “’ />”).Length.Dump();


client.Dispose();

The length dumps are given to get an idea of what size would be added to a file if added inline.
