Why repost the question? Also, what's wrong with you posting on a respectable site with that nickname, be it a phallus or a rooster I don't care. This is unacceptable

Just go to OPs profile page and report as Spammer\Abusive. A whole bunch of members already got the boot for using abusive names. Once a member has been reported 5 times the account is automatically deactivated.

Guys, please relax. The guy is from India. Stop measuring everything with your Western standards. A name is a name. Many names in some languages sound like taboo words in others.

Anyway, i'm not going to take it personal with your nick name and the like but please do take advise.
Below is the code i would use to convert an image to text, well basically to it's base64 representation, that's if i got your question right:

    System.Drawing.Image img = System.Drawing.Image.FromFile( "img path here" );
    ImageFormat format = ImageFormat.Png;
    MemoryStream memory = new MemoryStream();
    img.Save( memory, format );
    string base64 = Convert.ToBase64String( memory.ToArray() );
    File.WriteAllText( "img.txt", base64 );
    Console.WriteLine( "data written to the chosen text file" );
catch ( Exception ex )
    Console.WriteLine( ex );

This works for me.
Happy coding,
