大家帮我看看那里错了

[zhuzhusexa]

我想出7个不重复的数字，，为什么还会有重复，，帮我看看应该改哪里
namespace 彩票
{
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
}

public int[] Radom()
{
Random random = new Random();
int[] array = new int[7];
array[0] = random.Next(1, 36);

int count = 1; //记录循环到第几位
while (count < 7)
{
int cache = random.Next(1, 36);
for (int i = 1; i < array.Length; i++)
{
if (array[i] == cache)
{
break;
}
else
{
array[count] = cache;
count++;
break;
}
}
}
return array;
}

private void button1_Click(object sender, EventArgs e)
{
DataList myData = new DataList();
myData.Array = Radom();
myData.Print();
}
}

class DataList
{
private int[] array;
public int[] Array
{
get
{
return array;
}
set
{
array = value;
}
}

public void Print()
{
StringBuilder str = new StringBuilder();
for (int i = 0; i < array.Length; i++)
{
str.Append(" " + array[i]);
}
MessageBox.Show(str.ToString());
}
}
}

[wangyue4]

if (array[i] == cache)
{
break;
}
如果重复应该count--后再跳出循环

[wangyue4]

else
{
array[count] = cache;
count++;
break;
}
这几句应该去掉

[wangyue4]

array[count] = cache;
放到for循环体外面

 for (int i = 1; i < array.Length; i++)
  {
  if (array[i] == cache)
  {
  break;
  } 
  array[count] = cache;
  count++;
  break;
  
  }

把 循环改成这样来写

[gomoku]

public int[] Radom()
{
    Random random = new Random();
    int[] array = new int[7];
    int count = 0; //记录循环到第几位
    while (count < 7)
    {
        int num = random.Next(1, 36);
        if (Array.IndexOf<int>(array, num) < 0)
        {
            array[count++] = num;
        }
    }
    return array;
}

上面 给错了 下面代码

 for (int i = 1; i < array.Length; i++)
  {
  if (array[i] == cache)
  {
  break;
  }
  array[count] = cache;
  count++;  
  }
