C#字符串解析成16进制,并计算校验和

 代码如下,分成两个步骤:

1、将字符串分割;

2、将字符串按16进制解析成整数;

3、计算校验和;

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;

namespace test
{
    class Program
    {
        static void Main(string[] args)
        {
            string str = "55 AA 00 00 00 00 00 00 01 00 00 00 32 ";
            char[] chs = { ' ' };
            string [] result = str.Split(chs, options: StringSplitOptions.RemoveEmptyEntries);
            byte[] res = new byte[result.Length];

            for (int i = 0; i < result.Length; i++)
            {
                res[i] = Convert.ToByte(result[i], 16);
            }            

            byte checkNum = 0;
            for (int i = 0; i < res.Length - 1; i++) //求校验和
            {
                checkNum += res[i];
            }
            if (checkNum == res[res.Length - 1])
            {
                Console.WriteLine("ok");
            }

            Console.WriteLine(res.Length);

            Console.ReadKey();
        }
    }
}
