listview C＃按特定列排序

Question

如何在WinForms .NET 2.0中按特定列號對列表視圖控件進行排序？例如我有一個名爲「Line Number」的索引爲1的列，我想按升序對列表視圖中的項目進行排序。

Answer 1

我已經在很多的Winform項目中使用此列分揀機：

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(); 
}

有例子MSDN上ListView.ColumnClick article：非常簡短。從本質上講，你寫一個ListViewItemComparer，並用它每次單擊列：

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); 
    } 
}
