TreeNode.Text 属性
获取或设置在树节点标签中显示的文本。
**命名空间:**System.Windows.Forms
**程序集:**System.Windows.Forms（在 system.windows.forms.dll 中）
语法
声明
<LocalizableAttribute(True)> _
Public Property Text As String
用法
Dim instance As TreeNode
Dim value As String
value = instance.Text
instance.Text = value
[LocalizableAttribute(true)]
public string Text { get; set; }
[LocalizableAttribute(true)]
public:
property String^ Text {
String^ get ();
void set (String^ value);
}
/** @property */
public String get_Text ()
/** @property */
public void set_Text (String value)
public function get Text () : String
public function set Text (value : String)
属性值
在树节点标签中显示的文本。
备注
如果父 TreeView 的 LabelEdit 属性设置为 false，用户将无法设置此属性。要显式设置此属性，一种替代方法是使用 TreeNode 构造函数之一创建树节点，使其具有表示 Text 属性的字符串参数。如果显示标签，则标签显示在 TreeNode 图像的旁边。
示例
下面的代码示例创建一个要为其分配子树节点的根树节点。将 ArrayList 中的每个 Customer 对象的一个子树节点以及分配给 Customer 对象的每个 Order 对象的一个子树节点添加到根树节点。将 Customer 对象分配给 Tag 属性，并将表示 Customer 对象的树节点用 Orange 文本显示。本示例要求已定义 Customer 和 Order 对象，Form 上具有 TreeView 控件，还要求有一个名为 customerArray 的 ArrayList，其中包含 Customer 对象。
