Explanation:

In the above program, we created a class ConvertDemo that contains two static methods hex2dec() and Main(). The hex2dec() method is used to convert a hexadecimal number into a decimal number using Parse() method of int structure. In the Main() method, we read the hexadecimal number and pass to the hex2dec() method that returns the converted decimal number then we printed the result on the console screen.
