converting a base 64 string to an image and saving it

I have a PNG image encoded as a Base64 string. I need to convert this string into PNG format. How can I convert this in C#?

Answer 1

using Convert=System.Convert;
using MemoryStream=System.IO.MemoryStream;
using Image=System.Drawing.Image;
//...

byte[] data = Convert.FromBase64String(base64String);
using(var stream = new MemoryStream(data, 0, data.Length))
{
  Image image = Image.FromStream(stream);
  //TODO: do something with image
}
