string DecimalToBase(int iDec, int numbase)
        {
            string strBin = "";
            int[] result = new int[32];
            int MaxBit = 32;
            for(; iDec > 0; iDec/=numbase)
            {
                int rem = iDec % numbase;
                    result[--MaxBit] = rem;
            } 
            for (int i=0;i= base10)
                    strBin += cHexa[(int)result.GetValue(i)%base10];
                else
                    strBin += result.GetValue(i);
            strBin = strBin.TrimStart(new char[] {'0'});
            return strBin;
        }
        int BaseToDecimal(string sBase, int numbase)
        {
            int dec = 0;
            int b;
            int iProduct=1;
            string sHexa = "";
            if (numbase > base10)
                for (int i=0;i=0; i--,iProduct *= numbase)
            {
                string sValue = sBase[i].ToString();
                if (sValue.IndexOfAny(cHexa) >=0)
                    b=iHexaNumeric[sHexa.IndexOf(sBase[i])];
                else 
                    b= (int) sBase[i] - asciiDiff;
                dec += (b * iProduct);
            } 
            return dec; 
        }
