C# - Base64 byte array to Image FAILS no matter what I try

Question

I\'m having trouble creating an Image/Bitmap object in C# from a base64 encoded byte array.

Here\'s what I\'m dealing with:

I think your problem is that you are taking a base64 string that was posted to your controller , treating it like ASCII, and then converting it to base64 again.

I think you need to change this line

byte[] imageBytes = Convert.FromBase64String(imageData.EncodeTo64());

to

byte[] imageBytes = Convert.FromBase64String(imageData);

from there your bytes should be correct and you should be able to create your image

--Edit--

I took the sample data you provided in the text document and parsed it before loading it into a Bitmap. I was able to save the image to my hard drive and was greeted by a Spartan (Go Green!!)

Give this code a try and see what happens.

Please note imageData is exactly what's exposed on http://kristianbak.com/test_image.txt. I would have provided the initialization, but it's a pretty big string and would probably break things.

string imageDataParsed = imageData.Substring( imageData.IndexOf( ',' ) + 1 );
byte[] imageBytes = Convert.FromBase64String( imageDataParsed );
using ( var imageStream = new MemoryStream( imageBytes, false ) )
{
   Bitmap image = new Bitmap( imageStream );
}
