Generate a sequence of numbers from 1, 2, 3, ...9, A , B...Z, 10, 11, 12, 13, ......19, 1A.

if you have any solution for this, please provide me

I can write my own code to generate this sequence

class SeqGen
{
  char [] code;

  public SeqGen()
  {
      code = new char[10];
      for(int n=0; n<10; n++) code[n]='0';
  }

  private void inc(int pos)
  {

    if (code[pos] == '9')
        code[pos] = 'A';
    else if (code[pos]=='Z')
    {
      if ( pos==0)
        throw new Exception("overflow");
      code[pos] = '0';
      inc(pos-1);
    }
    else
    {
      code[pos]++;
    }
  }

  public void inc()
  {
    inc(9);
  }
  public  override string ToString()
  {
     return new string(code).TrimStart(new char [] {'0'});
  }
}

class Program
 {
   static void Main()
   {
     SeqGen sg = new SeqGen();
     for (int i = 0; i < 100; i++)
     {
       sg.inc();
       Console.WriteLine("i={0}, code={1}", i, sg.ToString());
     }
   }
 }
