本文介绍了一个使用ASP.NET实现的用户控制组件，包括获取用户输入、展示欢迎信息和反向显示用户名的实现过程。

3 user controls:

1) GetName.aspx

<%@ Control Language="C#" AutoEventWireup="true" CodeBehind="GetName.ascx.cs" Inherits="WebApplication12.GetName" %>
Please type your name:<asp:TextBox ID="NameTextBox" runat="server"></asp:TextBox>
<asp:Button ID="Button1" runat="server" Text="Submit" OnClick="SubmitButton_Click" />

GetName.aspx.cs

 public partial class GetName : System.Web.UI.UserControl
    {
        protected void Page_Load(object sender, EventArgs e)
        {

        }

        private string _name = string.Empty;
        protected void SubmitButton_Click(object sender, EventArgs e)
        {
            _name = NameTextBox.Text;
        }
        [ConnectionProvider("User name provider", "GetUserName")]
        public string GetUserName()
        {
            return _name;
        }
    }

2)GreetUser.aspx

<%@ Control Language="C#" AutoEventWireup="true" CodeBehind="GreetUser.ascx.cs" Inherits="WebApplication12.GreetUser" %>
<asp:Label ID="GreetingLabel" runat="server" Text="Label"></asp:Label>

GreetUser.aspx.cs

 public partial class GreetUser : System.Web.UI.UserControl
    {
        protected void Page_Load(object sender, EventArgs e)
        {

        }

        [ConnectionConsumer("User name consumer", "GetName")]
        public void GetName(string Name)
        {
            GreetingLabel.Text = "Welcome, " + Name + "!";
        }
    }

3)ShowNameBackwards.aspx

<%@ Control Language="C#" AutoEventWireup="true" CodeBehind="ShowNameBackwards.ascx.cs" Inherits="WebApplication12.ShowNameBackwards" %>
<asp:Label ID="BackwardsLabel" runat="server" Text="Label"></asp:Label>

ShowNameBackwards.aspx.cs

 public partial class ShowNameBackwards : System.Web.UI.UserControl
    {
        protected void Page_Load(object sender, EventArgs e)
        {

        }

        [ConnectionConsumer("User name consumer", "GetName")]
        public void GetName(string Name)
        {
            char[] NameCharArray = Name.ToCharArray();
            Array.Reverse(NameCharArray);
            BackwardsLabel.Text = "Your name backward is: " +
            new string(NameCharArray);
        }
    }
