C# Hex String into Hex int

Question

Can someone edit this to look better? Thanks!

I'm trying to have a string that is a Hex value but it is set by a third party (Not The Code Itself) and set it back to an int but still be a Hex value. C# Will let you have an int that is equal to a Hex if you have the 0x in front.

Code:

string HexValue = "0x0FC";
int OtherValue = Convert.ToInt(HexValue);

When I try this I get: 'Input string was not in a correct format.'

This question already has an answer here: http://stackoverflow.com/a/4280019/2850543 — Millie Smith, Mar 21 '17 at 03:05

You can convert string into a int hex value by adding this System.Globalization.NumberStyles.HexNumber:

string HexValue = "0x0FC";
int OtherValue = int.Parse(HexValue.Substring(2),System.Globalization.NumberStyles.HexNumber);

Hope it helps!

Had to take away my upvote because you didn't run the code. It doesn't work with `0x` on the front – Millie Smith Mar 21 '17 at 03:04
Ooops, updated my answer. You're not allowed to pass string with leading "0x", so you should remove it thru substring. – mindOfAi Mar 21 '17 at 03:07
@mindOfAi Ok that worked not instead of posting a new thing how would I do this?: string Value = "0.0F"; float NewValue = Value; – Because Of Cancer Mar 21 '17 at 03:13
You can just do this: string Value = "0.2F"; float NewValue = float.Parse(Value.TrimEnd('F')); – mindOfAi Mar 21 '17 at 03:23
