生产不同的 key

Question

求高手,帮我写一段代码,循环产生不同的八个字符的 key.例如:   nGa[rwkH
不知道.为什么,我循环,产生出来的 key 都是相同的.

Answer 1

用下面范围内的字符生成八位字符的Key.
A-Z
a-z
0-9
[]像这样的:  nGa[rwkH 

Answer 2

key是相同的八成是LZ的Random使用有误.
把Random变量改成静态变量试试.

Answer 3

如果是要得到每个字符
用foreach循环遍历就好了

using System;
using System.Collections.Generic;
using System.Text;namespace radam
{
    class Program
    {
        static int GetRandomSeed()
        {
            byte[] bytes = new byte[4];
            System.Security.Cryptography.RNGCryptoServiceProvider rng = new System.Security.Cryptography.RNGCryptoServiceProvider();
            rng.GetBytes(bytes);
            return BitConverter.ToInt32(bytes, 0);
        }        static void Main(string[] args)
        {
            string[] a ={"a","b","c","d","e","f","g","h"
                ,"i","j","k","l","m","n","o","p","q","r"
                ,"s","t","u","v","w","x","y","z","A","B"
                ,"C","D","E","F","G","H","I","J","K","L"
                ,"M","N","O","P","Q","R","S","T","U","V"
                ,"W","X","Y","Z","0","1","2","3","4","5"
                ,"6","7","8","9","[","]"};
            string s = string.Empty;
            for (int i = 0; i <8;i++ )
            {
                Random r = new Random(GetRandomSeed());
                int j=r.Next(0,63);
                 s = s + a[j];
                 
               
            }
            Console.WriteLine(s);
                        }
        }
    
}

Answer 5

string s = string.Empty;
            List<string> key = new List<string>();
            for (int k=0;k<1000;k++)
            {
                for (int i = 0; i < 8; i++)
                {
                    Random r = new Random(GetRandomSeed());
                    int j = r.Next(0, 63);
                    s = s + a[j];
                }
                if (!key.Contains(s))
                    key.Add(s);
                else
                    s = string.Empty;
            }

Answer 6

static int GetRandomSeed()
        {
            byte[] bytes = new byte[4];
            System.Security.Cryptography.RNGCryptoServiceProvider rng = new System.Security.Cryptography.RNGCryptoServiceProvider();
            rng.GetBytes(bytes);
            return BitConverter.ToInt32(bytes, 0);
        } string s = string.Empty;
            List<string> key = new List<string>();
          whilie(key.Count<8)
            {
                for (int i = 0; i < 8; i++)
                {
                    Random r = new Random(GetRandomSeed());
                    int j = r.Next(0, 63);
                    s = s + a[j];
                }
                if (!key.Contains(s))
                    key.Add(s);
                else
                    s = string.Empty;
            }
