【www.gdgbn.com--php函数】

随机数计算的根源,就是随机种子数,我原来用的是时间的毫秒,但是时间太快的话,就会导致取出的数字一样

如果加入调用次数作为参数呢:

asp教程.net中应用

<%@ page language="c#" contenttype="text/html" responseencoding="gb2312" %>
  <script runat="server">
  void page_load(object sender,eventargs e){
   random objrandom=new random();
   label_1.text=convert.tostring(objrandom.next(100));
  }
  </script>

测试实例

public static class getint
{
    public static int c;
    public static int getone()
    {
        c++;
        random ran = new random(datetime.now.millisecond + c);
        return ran.next(0, getarg.getmax());
    }
}

官网实例

byte[] bytes1 = new byte[100];
byte[] bytes2 = new byte[100];
random rnd1 = new random();
random rnd2 = new random();

rnd1.nextbytes(bytes1);
rnd2.nextbytes(bytes2);

console.writeline("first series:");
for (int ctr = bytes1.getlowerbound(0);
     ctr <= bytes1.getupperbound(0);
     ctr++) {
   console.write("{0, 5}", bytes1[ctr]);
   if ((ctr + 1) % 10 == 0) console.writeline();
}
console.writeline();
console.writeline("second series:");       
for (int ctr = bytes2.getlowerbound(0);
     ctr <= bytes2.getupperbound(0);
     ctr++) {
   console.write("{0, 5}", bytes2[ctr]);
   if ((ctr + 1) % 10 == 0) console.writeline();
}
