listview C#按特定列排序[重复]

Question

如何在 WinForms .NET 2.0 中按特定列号对列表视图控件进行排序？例如我有一个名为“行号”的列，其索引为 1，我想按升序对列表视图框中的项目进行排序。

Answer 1

我在很多 Winform 项目中都使用过这个列排序器：

private void listView1_ColumnClick(object sender, 
                   System.Windows.Forms.ColumnClickEventArgs e)
{
   ListView myListView = (ListView)sender;

   // Determine if clicked column is already the column that is being sorted.
   if ( e.Column == lvwColumnSorter.SortColumn )
   {
     // Reverse the current sort direction for this column.
     if (lvwColumnSorter.Order == SortOrder.Ascending)
     {
      lvwColumnSorter.Order = SortOrder.Descending;
     }
     else
     {
      lvwColumnSorter.Order = SortOrder.Ascending;
     }
   }
   else
   {
    // Set the column number that is to be sorted; default to ascending.
    lvwColumnSorter.SortColumn = e.Column;
    lvwColumnSorter.Order = SortOrder.Ascending;
   }

   // Perform the sort with these new sort options.
   myListView.Sort();
}

MSDN 上有示例ListView.ColumnClick article：非常简短。本质上，您编写一个ListViewItemComparer 并在每次单击列时使用它：

 class ListViewItemComparer : IComparer
 {
    private int col = 0;

    public ListViewItemComparer(int column)
    {
        col = column;
    }
    public int Compare(object x, object y)
    {
        return String.Compare(((ListViewItem)x).SubItems[col].Text, ((ListViewItem)y).SubItems[col].Text);
    }
 }

 class MyForm : Form
 {
    // private System.Windows.Forms.ListView listView1;

    // ColumnClick event handler.
    private void ColumnClick(object o, ColumnClickEventArgs e)
    {
        this.listView1.ListViewItemSorter = new ListViewItemComparer(e.Column);
    }
 }
