通过

Xml.AddParsedSubObject(Object) 方法

  • 参考

定义

命名空间:
System.Web.UI.WebControls
程序集:
System.Web.dll

通知服务器控件，分析了一个元素（XML 或 HTML），并将该元素添加到服务器控件的 ControlCollection 对象中。

protected:
 override void AddParsedSubObject(System::Object ^ obj);
protected override void AddParsedSubObject (object obj);
override this.AddParsedSubObject : obj -> unit
Protected Overrides Sub AddParsedSubObject (obj As Object)

参数

obj
Object

一个 Object，表示已经过分析的元素。

例外

HttpException

obj 的类型不是 LiteralControl。

示例
