C＃十六进制计算器帮助。 [英] C# hex calculator help.

问题描述

朋友你好。我需要一个六角计算器。我做不到。你的建议是什么？我想要的是这样的;



例如;

Hello friends. I need a hex calculator. I could not do. What is your suggestion. What I want is exactly like this ;

for example;

Hexdata = "2020202020442042497c31323334414243353637387c";

计算;



20 + 20 + 20 + 20 + 20 + 44 + 20 + 42 + 49 + 7c + 31 + 32 + 33 + 34 + 41 + 42 + 43 + 35 + 36 + 37 + 38 + 7c = 4f1

calculation;

20+20+20+20+20+44+20+42+49+7c+31+32+33+34+41+42+43+35+36+37+38+7c = 4f1

result= "4f1";

private void HexCalc(string data) 
{

 //Code Here.....

}

感谢您的帮助。我为糟糕的英语和叙述道歉。



我尝试了什么：

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

What I have tried:

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;
                }
               
            }
        }

推荐答案

嗯，你没有显示我们你的ConvertToHex方法，所以我假设那是你出错的地方。

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

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();
}

此外，我只是为数学部分做这个：

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

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