void Main()
{
       string cardPass="654311";
if (!Regex.IsMatch(cardPass, @"^\d{6}$") || Regex.IsMatch(cardPass, @"^(\d)\1{5}$"))
{
//isSpecialAllowed = false;
}
else
{ 
      if(!IsOrdered(cardPass) || !IsOrdered(new string(cardPass.ToCharArray().Reverse().ToArray())))
  {
  //禁止顺序 倒序   } }
}
static bool IsOrdered(string testStr)
{
if (string.IsNullOrEmpty(testStr))
return false;
  
int count = testStr.Length; for (int i = 0; i < count - 1; i++)
{
if (testStr[i + 1] <= testStr[i])
