Question

i have a text box on my form. I want to write “0x31” as a string to my textbox and then when i clicked a button, i want to convert this string to 0x31 as a hexadecimal value.

How can i convert this string to hexadecimal value?

Answer 1

string hexValues = "48 65 6C 6C 6F 20 57 6F 72 6C 64 21";
string[] hexValuesSplit = hexValues.Split(' ');
foreach (String hex in hexValuesSplit)
{
    // Convert the number expressed in base-16 to an integer.
    int value = Convert.ToInt32(hex, 16);
    // Get the character corresponding to the integral value.
    string stringValue = Char.ConvertFromUtf32(value);
    char charValue = (char)value;
    Console.WriteLine("hexadecimal value = {0}, int value = {1}, char value = {2} or {3}",
                    hex, value, stringValue, charValue);
}
