Hex -> Dec & Dec -> Hex

Question

Does anyone have idea how to implement methods for converting hex number to dec number, and also converting from dec number to hex number?

Thanks

Mike

Answer 1

I found a good code sample at: 

http://www.geekpedia.com/Question8_How-do-I-convert-from-decimal-to-hex-and-hex-to-decimal.html

// Store integer 182
int decValue = 182;
// Convert integer 182 as a hex in a string variable
string hexValue = decValue.ToString("X");
// Convert the hex string back to the number
int decAgain = int.Parse(hexValue, System.Globalization.NumberStyles.HexNumber);

If you want a custom C# implementation that can convert a number from any numeral system to decimal and vice versa, take a look at the following articles:
