推荐答案

您可以使用列表，例如:-

假设这些是您的控件:

you can use List, Example:-

suppose these are your controls:

<asp:textbox id="TextBox1" runat="server"></asp:textbox>
<asp:textbox id="TextBox2" runat="server"></asp:textbox>
<asp:textbox id="TextBox3" runat="server"></asp:textbox>
<asp:button id="AddButton" runat="server" text="Add" onclick="AddButton_Click" />
<asp:button id="ShowDataButton" runat="server" onclick="ShowDataButton_Click" text="Show Data"/>

代码是:

The code is:

public partial class WebForm1 : System.Web.UI.Page
{
    public List<FormModel> FromData
    {
        get
        {
            if (ViewState["__FromData"] == null)
                ViewState["__FromData"] = new List<FormModel>();
            return (List<FormModel>)ViewState["__FromData"];
        }
    }

    protected void AddButton_Click(object sender, EventArgs e)
    {
        FromData.Add(new FormModel()
        {
            Text1 = TextBox1.Text,
            Text2 = TextBox2.Text,
            Text3 = TextBox3.Text,
        });
    }

    protected void ShowDataButton_Click(object sender, EventArgs e)
    {
        foreach (var item in FromData)
        {
            Response.Write(item.Text1 + "," + item.Text2 + "," + item.Text3);
            Response.Write("<br />");
        }
    }
}

[Serializable]
public class FormModel
{
    public string Text1 { get; set; }
    public string Text2 { get; set; }
    public string Text3 { get; set; }
}
