[C#] Gmail Dot Trick

This was one of the first things I made when I started C# so it's kinda messy.

PHP Code:

---

            public String DotTrick(String Email)
        {
            String Str = String.Empty;
            foreach (char character in Email.ToLower())
            {
                if (character.ToString() != "@")
                {
                    Str += character.ToString();

                    for (int x = 0; x < random.Next(random.Next(1, 10), random.Next(11, 15)); x++)
                    {
                        Str += ".";
                    }
                }
                else
                {
                    break;
                }
            }
            Email += "@gmail.com";
            return Email;
        }
