read picture with stream
example
string pic = "نام عکس مورد نظر";
string yourpath = Environment.CurrentDirectory + #"\Pic\"+pic;
FileStream stream = new FileStream(yourpath, FileMode.Open, FileAccess.Read);
FileToSend fs = new FileToSend("photo3.jpg",stream);
bot.MakeRequestAsync(new SendPhoto(update.Message.Chat.Id, fs)).Wait();
