 //Code Here.....

}

Thanks for your help. I apologize for the bad english and the narration.

What I have tried:

C#

string hex;
string result;
int count;

 private void button2_Click(object sender, EventArgs e)
        {
            string data = dataBox.Text;
            string hexdata = ConvertToHex(data);

            for (var i = 0; i< hexdata.Length; i+= 2)
            {
                hex = hexdata.Substring(i, 2);
                count += 2;
                result = Convert.ToString(toplam + hexdata.Substring(count,2));
                if(i == hexdata.Length)
                {
                    textBox7.Text = Convert.ToString(result);
                    return;
                }
               
            }
        }

Well, you didn't show us your ConvertToHex method, so I'm assuming that's where you went wrong.

C#

public static byte[] StringToByteArray(string text) 
{
    return Enumerable.Range(0, text.Length)
                     .Where(x => x % 2 == 0)
                     .Select(x => Convert.ToByte(text.Substring(x, 2), 16))
                     .ToArray();
}

Further, I would simply do this for the math part:

C#

string text = "2020202020442042497c31323334414243353637387c";
int total = this.StringToByteArray(text).Sum(x=>x);
string totalStr = string.Format("{0:x}", total);
