如何在我的應用程序設置中保存複選框'在樹形視圖中檢查？

Question

我在尋找如何將選中的複選框保存在包含大量文件夾和子文件夾的樹視圖中。是否可以將它們保存在應用程序設置中？

Answer 1

可以存儲Dictionary(Of String, Boolean)和使用每個樹節點的獨特Name（或FullPath）物業：

Dim d As New Dictionary(Of String, Boolean) 
    Dim stack As New Stack(Of TreeNode) 

    For Each n As TreeNode In Me.TreeView1.Nodes 
     stack.Push(n) 
    Next 

    While stack.Count > 0 
     Dim node As TreeNode = stack.Pop() 

     For Each subNode As TreeNode In node.Nodes 
      stack.Push(subNode) 
     Next 

     d.Add(node.Name, node.Checked) 
    End While 

    ' Store d in My.Settings or somewhere else 

要恢復很容易 - 環比字典和名稱（設置Checked值或路徑）。
