HtmlTableRowCollection 类

定义

HtmlTableRow 对象的集合,这些对象表示 HtmlTable 控件中的行。A collection of HtmlTableRow objects that represent the rows of an HtmlTable control. 此类不能被继承。This class cannot be inherited.

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

HtmlTableRowCollection
实现

示例

下面的代码示例演示如何通过向HtmlTable HtmlTableRowCollection集合添加行来动态生成控件的内容。The following code example demonstrates how to dynamically generate the contents of an HtmlTable control by adding rows to an HtmlTableRowCollection collection. 请注意, Rows表的属性HtmlTableRowCollection是对象。Notice that the Rows property of a table is the HtmlTableRowCollection object.

注解

使用类以编程方式管理HtmlTableRow对象的集合, 这些对象HtmlTable表示控件中的行。 HtmlTableRowCollectionUse the HtmlTableRowCollection class to programmatically manage a collection of HtmlTableRow objects that represent the rows in an HtmlTable control. 此类通常用于在HtmlTable控件中添加、移除或修改行的内容。This class is commonly used to add, remove, or modify the contents of a row in an HtmlTable control.

备注

控件包含一个Rows表示对象集合的HtmlTableRow属性。 HtmlTableAn HtmlTable control contains a Rows property that represents a collection of HtmlTableRow objects. HtmlTableRow个都表示表中的单个行。Each HtmlTableRow represents an individual row in the table. 包含一个Cells表示对象集合的HtmlTableCell属性。 HtmlTableRowAn HtmlTableRow contains a Cells property that represents a collection of HtmlTableCell objects. 这些对象又分别表示表的各个单元。These objects, in turn, represent the individual cells of the table. 若要检索单个单元格, 请首先HtmlTableRow RowsHtmlTable控件的集合中获取表示该单元格的行的对象。To retrieve an individual cell, first get the HtmlTableRow object, representing the row containing the cell, from the Rows collection of the HtmlTable control. 然后, 可以Cells从的HtmlTableCell集合HtmlTableRow中获取表示行中的单元格的对象。You can then get the HtmlTableCell object, representing the cell in the row, from the Cells collection of the HtmlTableRow.
