随机数索引生成代码:
using System; using System.Collections.Generic; using System.Linq; using System.Text; using System.Threading.Tasks; namespace YpDotNetCoreTaskWinForm.Common { internal class RandomHelper { public int GetRandomNumberDelay(int min, int max) { Thread.Sleep(GetRandomNumber(300, 500)); return GetRandomNumber(min, max); } private int GetRandomNumber(int min, int max) { Guid guid=Guid.NewGuid(); //每次生成一个全新的ID string sGuid=guid.ToString(); int seed = DateTime.Now.Millisecond; for (int i = 0; i < sGuid.Length; i++) { switch (sGuid[i]) { case 'a': case 'b': case 'c': case 'd': case 'e': case 'f': case 'g': seed = seed + 1; break; case 'h': case 'i': case 'j': case 'k': case 'l': case 'm': case 'n': seed = seed + 2; break; case 'o': case 'p': case 'q': case 'r': case 's': case 't': seed = seed + 3; break; case 'u': case 'v': case 'w': case 'x': case 'y': case 'z': seed = seed + 3; break; default: seed = seed + 4; break; } } Random random=new Random(seed); return random.Next(min, max); } } }
具体业务实现代码:
