大家好，今天跟大家學習寫一個亂數密碼產生器

1. Controller

public ActionResult Index()
            {   //密碼亂數
                string allowedChars = "abcdefghijkmnopqrstuvwxyzABCDEFGHJKLMNOPQRSTUVWXYZ0123456789";
                int passwordLength = 6;//密碼長度
                char[] chars = new char[passwordLength];
                Random rd = new Random();

                for (int i = 0; i < passwordLength; i++)
                {
                    //allowedChars -> 這個String ，隨機取得一個字，丟給chars[i]
                    chars[i] = allowedChars[rd.Next(0, allowedChars.Length)];
                }

                string password = new string(chars);

                ViewBag.password = password;


                return View();
            }

2.View

@{
    ViewBag.Title = "Index";
}

<h2>Index</h2>

@ViewBag.password
