<br />
<br />
1、不允许使用数据库，所有数据必须在后台生成。<br />
2、股票原始单价为1元,交易量在0-999999之间。<br />
3、涨幅在正负10%，且涨幅可以累加。比如原始单价为1元，第一刷新时上涨10%，此时的单价为1.1，第二次刷新也上涨10%，则此时的单价为1.21。涨、平、跌的概率均为1/3<br />
4、数据刷新时间为5秒。<br />
5、涨幅栏的数据为单次的涨幅。<br />
6、成交价低于0.5时，停止交易20次（即套牢），此行数据显示为灰色。20次交易后重新按原值(1.0)重新上市交易。<br />
7、测试时间为5小时(13:00-18:00)<br />
8、测试结果直接把源文件打包，发送给监考人。<br />
9、分值分布，数据表60分，图形表20分，套牢功能20分。<br />
数据表:初始化成功无错误10分，走势与涨跌10分，涨幅20分，成交价10分，成交金额和成交量10分<br />
图形表:初始化成功10分，图形10分<br />
套牢:套牢功能实现15分，解套5分<br />

如果触发Randm函数间隔时间很短，就有可能造成产生一样的随机数
没有产生相同的随机数啊。
我调试的时候 到这一步
gv.DataSource = dt;
gv.DataBind();
dt里面的值都是不一样的。 页面显示却是一样了。
double zs = rs.NextDouble();
Random rf = new Random();
double zf = rf.Next(0, 1000);
Random rc = new Random();
int zc = rc.Next(0, 999999);你的代码这样写是不行的,
你知不知道什么叫随机种子呀,首先, new Random() 方法必须放在循环外
其次, 你的这几个 new Random() 根本不需要那么多,只需要保留一个Random就可以了,由一个Random对象来产生随机数, 否则你这三个对象产生的对象值都是一样的, 不过是这些值,因为方法不一样,被限制,使得值看起来不一样.然后你不要急着辩解,先照着改完之后,试完再说.
调试的时候,不一样,是因为要判断是否命中断点或是执行语句之间,花的时间太多,导致时间种子不一样了,所以看到数据是不一样的,Random rs = new Random();
Random rf = new Random();
Random rc = new Random();这三个随机数对象,种子都是一样的(因为计算机处理这三条语句所需要的时间差,是Random对象不能识别的,时间差小到被认为是同一时刻,因此他们的种子是一样的),所以他们产生的随机值也是一样的, 这样的三个对象是完全没有意义的,你需要一个就可以了,
以下这样的调用的话, 就不会重复了.Random rand= new Random();
double rd = rand.NextDouble();
double zf = rand.Next(0, 1000);
int zc = rand.Next(0, 999999);
{
DataTable dt = Session["dt"] as DataTable;
Random random = new Random();
foreach ( DataRow dr in dt.Rows )
{
double zs = random.NextDouble();
double zf = random.Next( 0, 1000 );
int zc = random.Next( 0, 999999 );
