推荐答案

在表单上放置一个ID为"placeHolder"的placeHolder，并将以下代码添加到您的Page_Load()...

Put a placeHolder on your form with the ID "placeHolder" and add the following code to your Page_Load()...

CheckBoxList cbList = new CheckBoxList();

for (int i = 0; i < 10; i++)
    cbList.Items.Add(new ListItem("Checkbox " + i.ToString(), i.ToString()));

placeHolder.Controls.Add(cbList);

这将在CheckBoxList(cbList)中添加10个CheckBox对象.

This will add 10 CheckBox objects within your CheckBoxList(cbList).

使用以下代码检查CheckBoxList中的每个CheckBox对象

Use the following code to examine each CheckBox object within the CheckBoxList

foreach(ListItem li in cbList.Items)
{
    var value = li.Value;
    var text = li.Text;
    bool isChecked = li.Selected;
}

占位符用于在运行时将CheckBoxList添加到表单中，使用占位符可以让您更好地控制CheckBoxList及其项在网页中的显示位置

The placeholder is used to add the CheckBoxList to the form at runtime, using a placeholder will give you more control over where in the web page the CheckBoxList and its items will appear
