C # decimal and 16 binary conversions

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

Decimal to hexadecimal:

1 int a = 100;2 String stra = a.tostring ("x8");

Hexadecimal to decimal:

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

You can also use the following methods:
