Good morning everyone,

I need your help, I thank you in advance

I have a string like "sample". I need to get a string of it in hex format; like this:

%48%65%6C%6C%6F%20%57%6F%72%6C%64%21 <=> 'Hello World!'

I need a metod that let me Conversion from and to hexadecimal format. I'm programming on the Dynamics Nav 2015 platform.


Thank you so much in advance

Michele

    string input = "Hello World!";
char[] values = input.ToCharArray();
foreach (char letter in values)
{
    // Get the integral value of the character.
    int value = Convert.ToInt32(letter);
    // Convert the decimal value to a hexadecimal value in string form.
    string hexOutput = String.Format("{0:X}", value);
    Console.WriteLine("Hexadecimal value of {0} is {1}", letter, hexOutput);
}
/* Output:
   Hexadecimal value of H is 48

    HtmlEncode method of the HttpUtility calss doesn't allow to convert the whole string in hexadecimal format but converts only a part of it :neutral:
