use this one using  (MemoryStream ms =  new  MemoryStream(bytes))              {                  image = Image.FromStream(ms);              }

Sachin Singh · Answer

just use another version of memorystream that takes one argument only   using  (var ms =  new  MemoryStream(bytes))    {   .......   write to stream         }

Thanks Sachin for your code. I just digged it, basically for all base64 image this code is working. If its base64 pdf then this issue coming. I am not sure. but looks like. Is there a way to handle it in code.

Rajesh Kumar · Answer

It was working fine for some base64. But when i checked now. for some its same issue. Error triggering from below line   image1 = Image . FromStream ( ms , true );
