範例

以下程式碼範例以控制方式顯示客戶資訊 TreeView 。 根樹節點顯示客戶名稱，子樹節點則顯示分配給每位客戶的訂單號碼。 在此範例中，顯示 1,000 名客戶，每人有 15 筆訂單。 重新上色 TreeView 會被使用 BeginUpdate and EndUpdate 方法抑制，並顯示等待 Cursor 畫面，等待物件 TreeView 的建立與上色 TreeNode 。 這個例子要求你有一個 Customer 物件可以容納一組 Order 物件。 同時也要求你在 上Form建立了一個控制實例TreeView。

備註

這個版本 Add 的方法允許你將先前建立的 TreeNode 物件加入樹節點集合的末尾。

你也可以透過使用 AddRange or Insert 方法新增TreeNode物件到集合中。

要移除你之前新增的 ， TreeNode 請使用 Remove、 RemoveAt或 Clear 方法。

備註

A TreeNode 一次只能指派給一個 TreeView 控制點。 要將樹節點加入新的樹狀檢視控制項，必須先從另一個樹狀檢視中移除或複製它。

建立一個樹狀節點，包含指定的鍵、文字和圖片，並將其加入集合中。

public:
 virtual System::Windows::Forms::TreeNode ^ Add(System::String ^ key, System::String ^ text, int imageIndex, int selectedImageIndex);
public virtual System.Windows.Forms.TreeNode Add(string key, string text, int imageIndex, int selectedImageIndex);
public virtual System.Windows.Forms.TreeNode Add(string? key, string? text, int imageIndex, int selectedImageIndex);
abstract member Add : string * string * int * int -> System.Windows.Forms.TreeNode
override this.Add : string * string * int * int -> System.Windows.Forms.TreeNode
Public Overridable Function Add (key As String, text As String, imageIndex As Integer, selectedImageIndex As Integer) As TreeNode

參數

key
String

樹節點的名稱。

text
String

文字要顯示在樹節點中。

imageIndex
Int32

要在樹節點顯示的影像索引。

selectedImageIndex
Int32

當該影像處於選取狀態時，要在樹節點中顯示的索引。

傳回

TreeNode

被加入集合的樹節點。

備註

該Name性質對應於 中 a 的TreeNodeTreeNodeCollection鍵。

樹節點會被加入集合的末尾。 你也可以透過使用 AddRange or Insert 方法新增TreeNode物件到集合中。

參數imageIndex指的是父 屬性中的ImageListTreeView影像。

參數selectedImageIndex指的是父 屬性中的StateImageListTreeView影像。

適用於

Add(String, String, String, String)
