我需要对多个列表框中包含的数据进行排序。用户将能够使用无线电盒在两种不同类型的排序之间进行选择，其中一种默认情况下在表格加载时进行检查。我已经创建了所需的IF语句，以便测试该单选按钮的检查条件是否为真。但我需要一些帮助来创建自定义排序算法。
每个列表包含相似的查看数据，每行开始的唯一区别。例如，第一个列表框中的每一行以前缀“G30”开头，第二个列表框将以“G31”开头，依此类推。总共有10个列表框（就前缀而言为G30-G39）。
第一个搜索算法必须按前13个字符的数字顺序对行进行排序。
实施例： 这是数据在排序之前的样子
G35:45:58:11 JG07
G35:45:20:41 JG01
G35:58:20:21 JG03
G35:66:22:20 JG05
G35:45:85:21 JG02
G35:64:56:11 JG03
G35:76:35:11 JG02
G35:77:97:12 JG03
G35:54:29:11 JG01
G35:55:51:20 JG01
G35:76:24:20 JG06
G35:76:55:11 JG01
这就是它在排序后应该如何看待
G35:45:20:41 JG01
G35:45:58:11 JG07
G35:45:85:21 JG02
G35:54:29:11 JG01
G35:55:51:20 JG01
G35:58:20:21 JG03
G35:64:56:11 JG03
G35:66:22:20 JG05
G35:76:24:20 JG06
G35:76:35:11 JG02
G35:76:55:11 JG01
G35:77:97:12 JG03
如您所见，前缀相同。因此它被排序，最低，首先是下一对整数，然后是下一对和下一对，但不是“JG”之后的值。
第二种排序算法将忽略前13个字符，并按“JG”之后的值的顺序排序，最高位。
任何帮助？有些人为你代表：）

答案 0 :(得分：5)
第一种算法与字母顺序相同，因此您可以直接使用：
int res = string.Compare(first,second);
第二种算法是降序最后两个字符的字母顺序：
int res = -string.Compare(first.Substring(first.Length - 2, 2), second.Substring(first.Length - 2, 2));
要对列表进行排序，您有两个选择;第一个是创建自己的ListBox子类，并覆盖ListBox.Sort Method的MSDN页面上详述的Sort方法。
第二个（更简单和更丑陋）是将所有项目放入集合中，订购集合并替换列表中的项目，如下所示：
using System.Collections.Generic;
using System.Windows.Forms;
namespace WindowsFormsApplication1 {
public partial class Form1 : Form {
void SortListBox() {
List<string> items = new List<string>();
foreach (string value in listBox1.Items) {
items.Add(value);
}
items.Sort((first, second) => string.Compare(first, second));
listBox1.Items.Clear();
listBox1.Items.AddRange(items.ToArray());
}
}
}
希望这会有所帮助......

要更改ListBox的排序行为，必须实现自己的ListBox类。我已经为你编写了解决方案并对其进行了测试。
右键单击您的项目，选择“Add Class ...”并输入类名“CustomListBox”。将以下代码添加到名称空间之间的类中：
using System;
using System.Collections.Generic;
using System.Text;
using System.Windows.Forms; // You need this namespace for ListBox
public class CustomListBox : ListBox
{
public CustomListBox()
: base()
{
}
protected override void Sort()
{
if (this.Items.Count > 1)
{
bool swapped;
do
{
int counter = this.Items.Count - 1;
swapped = false;
while (counter > 0)
{
if (this.Items[counter].ToString().CompareTo(
this.Items[counter - 1].ToString()) == -1)
{
object temp = Items[counter];
this.Items[counter] = this.Items[counter - 1];
this.Items[counter - 1] = temp;
swapped = true;
}
counter -= 1;
}
}
while (swapped);
}
}
}
您需要对排序执行的操作是按字母顺序排序。根据上面的示例，您可以使用CompareTo方法确定哪个字符串位于另一个字符串之前或之后。
现在您已拥有自己的自定义ListBox，您可以向其添加其他属性和字段：
public class CustomListBox : ListBox
{
public bool SortByJG;
// Other code...
}
然后您可以更改排序方法以根据当前排序模式更改搜索，如下所示：
while (counter > 0)
{
bool swap;
if (this.SortByJG)
{
string[] breakDownCurrent = this.Items[counter].ToString().Split(' ');
string[] breakDownPrevious = this.Items[counter - 1].ToString().Split(' ');
if (breakDownCurrent[1].CompareTo(breakDownPrevious[1]) == -1)
{
swap = true;
}
}
else
{
if (this.Items[counter].ToString().CompareTo(
this.Items[counter - 1].ToString()) == -1)
{
swap = true;
}
}
if (swap)
{
object temp = Items[counter];
this.Items[counter] = this.Items[counter - 1];
this.Items[counter - 1] = temp;
swapped = true;
}
counter -= 1;
}
要进行排序，请在Sorted = true;上设置ListBox。
<强>更新 因为OP很难理解，所以这是整个班级：
using System;
using System.Collections.Generic;
using System.Text;
using System.Windows.Forms; // You need this namespace for ListBox
namespace WindowsApplication1
{
public class CustomListBox : ListBox
{
public CustomListBox()
: base()
{
}
public bool SortByJG;
protected override void Sort()
{
if (this.Items.Count > 1)
{
bool swapped;
do
{
int counter = this.Items.Count - 1;
swapped = false;
while (counter > 0)
{
bool swap = false;
if (this.SortByJG)
{
string[] breakDownCurrent = this.Items[counter].ToString().Split(' ');
string[] breakDownPrevious = this.Items[counter - 1].ToString().Split(' ');
if (breakDownCurrent[1].CompareTo(breakDownPrevious[1]) == -1)
{
swap = true;
}
}
else
{
if (this.Items[counter].ToString().CompareTo(
this.Items[counter - 1].ToString()) == -1)
{
swap = true;
}
}
if (swap)
{
object temp = Items[counter];
this.Items[counter] = this.Items[counter - 1];
this.Items[counter - 1] = temp;
swapped = true;
}
counter -= 1;
}
}
while (swapped);
}
}
}
}
您现在还可以添加自己的方法来使用指定的模式进行排序：
public void Sort(bool sortByJG)
{
this.SortByJG = sortByJG;
if (this.Sorted)
{
this.Sort();
}
else
{
this.Sorted = true;
}
}
