This is the core

Code

1 Private   Static   Long Getnext ( Int Seed)
2 {
3 Int Initseed = ( Int ) (Datetime. Now. ticks - Seed *   10000 );
4 Random ran =   New Random (initseed );
5 Double D;
6 Long RET;
7
8 Do
9 {
10 D = Ran. nextdouble ();
11 RET = Convert. toint64 (d * (Math. Pow ( 10 , 15 )));
12 }
13 While (Ret <= Min | RET > Max );
14
15 Return RET;
16 }

 

Then we use the combined array and the half-lookup method to process duplicate results. The result is random as the seed and the final result is obtained. Then, the 62 hexadecimal class is used to convert the result to 8 characters.
