求8个 不重复的 随机数
List<int> list = new List<int>();
bool end = true;
int row = -1;
while (end)
{
bool b = true;
if (list.Count == 0)
{
row = new Random().Next(dealerList.Rows.Count);
list.Add(row);
continue;
}
row = new Random().Next(dealerList.Rows.Count);
for (int i = 0; i < list.Count; i++)
{
if (list[i] == row)
{
b = false;
break;
}
}
if (b)
{
list.Add(row);
}
if (list.Count == 8)
{
end = false;
}
}
List<int> list = new List<int>();
var random = new Random(Environment.TickCount);
while(list.Count < 8)
{
var x = random.Next(int.MinValue, int.MaxValue);
if (!list.Contains(x))
list.Add(x);
}
