代码举例1:

dlist = New .Web.UI.WebControls.DropDownList
dlist.Items.Clear
dlist.ID = \"d\" & rs2.Fields(\"zdm\").Value

Do While Not rs3.EOF
    dlist.Items.Add(rs3.Fields(0).Value)
    rs3.MoveNext
Loop

td2.Controls.Add(dlist)

代码举例2:
TextBox textbox = TextBox;
textbox.ID = showReader.GetValue(0).;
this.Controls.Add(textbox);

代码举例3:
// Override to create repeated items.
protected override void CreateChildControls {
    object o = ViewState[\"NumItems\"];
     (o != null) {
       // Clear any existing child controls.
       Controls.Clear;

        numItems = ()o;
       for ( i=0; i < numItems; i) {
          // Create an item.
          RepeaterItem item = RepeaterItem(i, null);
          // Initialize the item from the template.
          ItemTemplate.InstantiateIn(item);
          // Add the item to the ControlCollection.
          Controls.Add(item);
       }
    }
}

备注
新Control控件添加到序号索引末尾Control控件可以是任何 ASP.NET 服务器Control控件、您创建自定义服务器Control控件或文本Control控件例子

若要将Control控件添加到集合中特定索引位置请使用 AddAt 思路方法
