HtmlTableRowCollection 類別

定義

public ref class HtmlTableRowCollection sealed : System::Collections::ICollection

public sealed class HtmlTableRowCollection : System.Collections.ICollection

type HtmlTableRowCollection = class
    interface ICollection
    interface IEnumerable

Public NotInheritable Class HtmlTableRowCollection
Implements ICollection

繼承

Object

HtmlTableRowCollection

實作

ICollection IEnumerable

範例

以下程式碼範例示範如何透過向集合加入列HtmlTable來動態產生控制項的內容HtmlTableRowCollection。 請注意 Rows ，表的屬性是物件 HtmlTableRowCollection 。
