推荐答案

在下面的.aspx文件中添加动态控件的示例代码.

To add dynamic control in your .aspx file below is sample code.

在.aspx文件中的div下方添加id为addControl的

Add below div in your .aspx file with id which is addControl

<div id="addControl" runat="server">
</div>

您可以通过在.cs文件中添加以下代码来创建动态TextBox控件.添加控件是上面定义的div的ID.

You can create dynamic TextBox control by adding below code in you .cs file. Add Control is a id of above define div.

 TextBox txt1 = new TextBox();
 txt1.ID = "txtOne";
 txt1.Text = "";
 txt1.CssClass = "myClass";
 txt1.ClientIDMode = System.Web.UI.ClientIDMode.Static;
 addControl.Controls.Add(txt1);

借助NameValueCollection，您可以获取TextBox的值.

With the help of NameValueCollection you can get the value of TextBox.

NameValueCollection frmCollection = Request.Form;
string inputString = frmCollection["txtOne"];

NameValueCollection表示关联的字符串键的集合和字符串值，可以通过键或通过索引.

NameValueCollection represents a collection of associated String keys and String values that can be accessed either with the key or with the index.
