Question

I want to receive a hex calculating on:

  static int count = 0;
  string s;
  private void SetClock_Click(object sender, EventArgs e)
   {
        count++;
        label5.Text = count.ToString("X2");
        DateTime time = DateTime.Now;
        s = "4D-" + "1A-" + "2B-" + "3C-" +(label5.Text);
        txtSend.Text = s;
   }

After that i remove the ‘-‘ between the code and i want to add the HEX calculated result after “(label5.text)”:

4D 1A 2B 3C (label5.text) (hex result on (4D 1A 2B 3C (label5.text))).

I can’t understand how to tell my program to get different bytes – 4D/1A/2B… This is actually what we can do with the calculator on Scientific Mode selected “hex function” and typing all those 4D 1A.. by pressing XOR.

Answer 1

As I understand Correctly, You want to apply XOR on your s value and store its result in HEX in to txtSend.Text If so you can try this

s = "4D-" + "1A-" + "2B-" + "3C-" +(label5.Text);
string [] allHaxValues= s.Split(new char[]{'-'});
int result = 0;

foreach(string haxValue in allHaxValues)
{
   result = result ^ Convert.ToInt32(haxValue, 16);
}
txtSend.Text = result.ToString("X");

IF label5.Text Contains 1 then result will be 41

like

result = 4D XOR 1A XOR 2B XOR 3C XOR 1
