自定义列表框排序

我需要对包含在多个列表框中的数据进行排序。 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。

示例：这是排序前数据的外观

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，前缀是相同的。 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，而不是“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，最高的第一个。

任何帮助？ theres一些代表给你:)

Answer 1

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”。 将以下代码添加到命名空间之间的类中：

 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); } } } 

您需要做的排序就是按字母顺序排序。 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; } 

要进行排序工作，请设置Sorted = true; 在ListBox 。

更新：因为OP很难理解，所以这是整个class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; } } 

Answer 2

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，您有两种选择; 第一个是创建自己的ListBox子类，并覆盖ListBox.Sort方法的MSDN页面上详述的Sort 方法 。

第二个（更简单和更丑陋）是将所有项目放在一个集合中，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 items = new List(); 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()); } } } 

希望这可以帮助…
