通达信trade.dll自动生成绑定账号dll的工具源代码

代码:

using System;
 using System.Collections.Generic;
 using System.IO;
 using System.Linq;
 using System.Text;

 namespace ConsoleOddCreator
 {
     class Program
     {
         static void Main()
         {
             UInt16 a3 = 0x55E;
             string gpdm = "";
             Console.Write("请输入账号：");
             string account = Console.ReadLine().Trim();
             Console.WriteLine("帐号的奇数位为：");
             for(int i= 0; i < account.Length; i+=2)   gpdm+=(account[i]);
             Console.WriteLine(gpdm);
             string result = "";
             for (int i = 0; i < gpdm.Length; i++)
             {
                 bool next = true;
                 int a = gpdm[i];
                 int b = a3 >> 0x8;
                 int c = a ^ b;
                 a3 = (UInt16)(0x207F * (a3 + c) - 0x523D);
                 for (int j = 65; j < 91 && next; j++)
                 {
                     for (int k = 90; k >= 65 && next; k--)
                     {
                         int temp = (1755 + c - k);
                         if (temp % 26 == 0 && temp / 26 == j)
                         {
                             result += (Char)j + "" + (Char)k;
                             next = false;
                         }
                     }
                 }
             }
             Console.WriteLine("生成的密文为：\n");
             Console.WriteLine(result);
             Console.WriteLine("正在绑定dll...");
             FileStreamReadFile("trade_raw.dll", "trade_" + account.Trim() + ".dll", result);
             Console.WriteLine("绑定成功！");
             Console.Read();
         }
