C # byte stream converted to picture code by BASE64 encoding

You need to load the following namespaces

Using System.IO;
Using System.Drawing;
Using System.Runtime.Serialization.Formatters.Binary;
protected void Page_Load (object sender, EventArgs e)
{
byte[] buffer = ReadFile (Server.MapPath (@ "\sex.txt"));
char[] ch = new ASCIIEncoding (). GetChars (buffer);//or: char[] ch = Encoding.UTF8.GetChars (buffer)
String base64 = ToBase64 ();
Turn into pictures and save
Toimage (base64);
System.Drawing.Image img = toimage (base64);
Img. Save (Server.MapPath (@ "\imgbase64.jpg"));
}

Read. Basestream.seek (0, Seekorigin.begin); Set the file pointer to the file open

FS. Close ();
