TableRowCollection.GetEnumerator 方法的C#例子
下面的示例展示如何使用 GetEnumerator 方法创建一个实现了 System.Collections.IEnumerator 的对象，该对象被循环访问以显示表中的项。view plaincopy to clipboardprint?<%@ Page Language="C#" AutoEventWireup="True" %> <HTML> <HEAD> <SCRIPT runat="server">

for (int j=0; j<numrows; j++) { 
TableRow r = new TableRow(); for (int i=0; i<numcells; i++) { TableCell c = new TableCell(); c.Text=counter.ToString(); r.Cells.Add(c); counter++; 
} Table1.Rows.Add(r); } 
} void Button_Click(object sender, EventArgs e) { int row_counter = 0; TableRow current_row; TableCell current_cell; // Create an IEnumerator for the rows of a table.
