How do I convert from decimal to hex and hex to decimal?

If for any reason you want to convert a decimal number to a hex value or vice versa here’s how it’s done in C#.

// 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);

In the above example we convert the decimal stored in the int variable named decValue and store it in a string variable named hexValue.
Then we convert the hex value stored as a string in the hexValue variable and store it in the variable named decAgain.
