问题描述
大家好!
我有一个问题,我无法理解,谷歌也不想帮助我:
我正在填写这样的列表框:
Hi everyone!
I have a problem where i can't get my head around, google didn't want to help me either:
I'm filling a listbox like this:
for (int i = 0; i < listbox1.Items.Count; i++)
{
for (int j = 0; j < listbox1.Items.Count; j++)
{
if (i < j)
{
if (generator.Next(0, 2) == 0)
{
listbox2.Items.Add(listbox1.Items[i] + " : " + listbox1.Items[j]);
}
else
{
listbox2.Items.Add(listbox1.Items[j] + " : " + listbox1.Items[i]);
}
}
}
}
在我的案例结果在listbox2中有6个项目(给定listbox1中有4个项目)。
现在我想按给定的顺序对项目进行排序,即:1,3,5, 6,4,2
可视化我想用listbox2获得的地方:
Item1 - > Item1
Item2 - > Item3
Item3 - > Item5
Item4 - > Item6
Item5 - > Item4
Item6 - > Item2
但是我觉得明确的顺序不应该那么重要(或者是它?),如果有一般的方法,我会更感兴趣标记我的项目有一个值,按升序排序......
我知道如何实现它?
which in my case results in listbox2 with 6 items in it (given listbox1 has 4 items in it).
Now i'd like to sort the items by a given order, which is: 1,3,5,6,4,2
Visualization of where i want to get with listbox2:
Item1 --> Item1
Item2 --> Item3
Item3 --> Item5
Item4 --> Item6
Item5 --> Item4
Item6 --> Item2
But i guess the explicit order shouldn't be that important (or is it?), i'd be more interested in if there's a general way of "tagging" my items with a value to ascendingly sort them by...
Any idea how i can implement that?
推荐答案
private void button1_Click(object sender, EventArgs e)
{
int[] array = { 4, 5, 8, 2, 6, 9, 1, 7 };
int[] arrayOdds = new int[array.Length];
int[] arrayPairs = new int[array.Length];
List<int> newArray = new List<int>();
//separate Odds from pairs
for (int i = 0; i < array.Length; i++)
{
if (array[i] % 2 == 1)
{
arrayOdds[i] = array[i];
}
else
{
arrayPairs[i] = array[i];
}
}
//bubble sort
for (int i = 0; i < array.Length; i++)
{
for (int j = 0; j < array.Length - 1; j++)
{
//bubble sort odds ascending
if (arrayOdds[j] > arrayOdds[j + 1])
{
int aux = arrayOdds[j];
arrayOdds[j] = arrayOdds[j + 1];
arrayOdds[j + 1] = aux;
}
//bubble sort pairs descending
if (arrayPairs[j] < arrayPairs[j + 1])
{
int aux = arrayPairs[j];
arrayPairs[j] = arrayPairs[j + 1];
arrayPairs[j + 1] = aux;
}
}
}
//get results together on a list
for (int i = 0; i < array.Length; i++)
{
if (arrayOdds[i] > 0)
newArray.Add(arrayOdds[i]);
}
for (int i = 0; i < array.Length; i++)
{
if (arrayPairs[i] > 0)
newArray.Add(arrayPairs[i]);
}
}
int[] order = new int[] { 1, 3, 5, 6, 4, 2 };
string[] sort = new string[12];
int f = 0;
foreach (object o in listbox2.Items)
{
sort[order[f]] = Convert.ToString(o);
f++;
}
listbox2.Items.Clear();
foreach (object o in sort)
{
if (o != null)
{
listbox2.Items.Add(o);
}
}
