Console.Write("Enter HEX: ");
string hexValues = Console.ReadLine();
string[] hexValuesSplit = hexValues.Split(new char[] { ' ' }, StringSplitOptions.RemoveEmptyEntries);
Console.WriteLine("HEX = DECIMAL");
foreach (String hex in hexValuesSplit)
{
    // Convert the number expressed in base-16 to an integer. 
    int value = Convert.ToInt32(hex, 16);
    Console.WriteLine(string.Format("{0} = {1}", hex, Convert.ToDecimal(value)));
}

Console.ReadKey();

Answer 2

use string.split(' ') to get your individual hex-numbers as a string-array. Then you can call

int dec = int.Parse(hex, System.Globalization.NumberStyles.HexNumber);

to convert each hex into its decimal representation.
