Convert Line Feed from string to hex

Hi,

I'm using the following code to convert a string to hex:

C#

char[] charArray = plainText.ToCharArray();
            StringBuilder sb = new StringBuilder();
            int num;
            string hex;
            for (int i = 0; i < charArray.Length; i++)
            {
                num = Convert.ToInt32(charArray[i]);
                hex = num.ToString("x");
                sb.Append(hex);
            }

The problem here is that, this code is converting all the line feeds into DA instead of 0A. According to the ASCII table to HEX:

DA - Ú
0A - linefeed

Does anyone got an idea about how can I convert the line feeds correctly?? Thanks, Nuno.

It is in fact true that using "x2" in the ToString method, converts the string correctly.

Thanks!

Solution 1

No it isn't: Look more closely and you will see it is actually outputting two values: "D" for Carriage return and "A" for Line feed.
To prove it, add a comma to each sb.Append.

Solution 2

Hi,
This is probably a formatting issue and what you are seeing is a carriage return (0xD) followed by a line feed(0xA). When num is < 0x10 ToString("x") will output only one character. "x2" will ensure that the output is padded with leading zeroes to a length of 2.

Numeric format strings[^]
