Code:

bool CheckCharName(string Gamertag)

Change:

Code:

---

    bool CheckCharName(string Gamertag)
    {
        char[] AllowedChars = " 1234567890abcdefghijklmnopqrstuvwxyz".ToCharArray();
        foreach (char c in Gamertag)
        {
            if (c.ToString().ToLower().IndexOfAny(AllowedChars) == -1)
            {
                return false;
            }


            if(Gamertag.Length >= 17) // long char name control
            {
                return false;
            }
        }
        return true;
    }

---

BUILD

or Sql Function

Code:

---

  if(LEN(@in_Gamertag) > 16)BEGIN
          select 'fuck' as ResultCode
                RETURN
        END

---

Why is the length check inside of the foreach? Should be like this instead:

Code:

---

bool CheckCharName(string Gamertag)
{
    if (Gamertag.Length >= 17) // long char name control
    {
        return false;
    }

    char[] AllowedChars = "1234567890abcdefghijklmnopqrstuvwxyz".ToCharArray();
    foreach(char c in Gamertag)
    {
        if (c.ToString().ToLower().IndexOfAny(AllowedChars) == -1)
        {
            return false;
        }
    }

    return true;
}
