In C #, the decimal and 16 binary conversions are simple, as follows:

`int  -  = a.tostring ("x8");`

`int b= int32.parse ("266", System.Globalization.NumberStyles.HexNumber);`

You can also use the following methods:

Length; i++) {String strnum=Nums[i]. ToString ().                    ToUpper (); Switch(strnum) { Case "A": Strnum="Ten";  Break;  Case "B": Strnum=" One";  Break;  Case "C": Strnum=" A";  Break;  Case "D": Strnum=" -";  Break;  Case "E": Strnum=" -";  Break;  Case "F": Strnum=" the";  Break; default:                             Break; }                    DoublePower = Math.pow ( -, Convert.todouble (nums. Length-i-1)); Total+ = Convert.ToInt32 (strnum) *Convert.ToInt32 (Power); }            }            Catch(System.Exception ex) {String Strerorr=Ex.                ToString (); return 0; }            returnTotal ; }`
