Step 3: Select "Deploy as a farm solution" as in the following and click the "Finish" button:

Step 4: The complete code of visualwebpart1usercontrol.ascx looks like this:

Step 5: The complete code of visualwebpart1usercontrol.ascx.cs looks like this:

using Microsoft.SharePoint;
using System;
using System.ComponentModel;
using System.Web.UI.WebControls.WebParts;namespace RenameDocLibApp.VisualWebPart1
{
    [ToolboxItemAttribute(false)]
    public partial class VisualWebPart1 : WebPart
    {

        // Uncomment the following SecurityPermission attribute only when doing Performance Profiling using
        // the Instrumentation method, and then remove the SecurityPermission attribute when the code is ready
        // for production. Because the SecurityPermission attribute bypasses the security check for callers of
        // your constructor, it's not recommended for production purposes.
        // [System.Security.Permissions.SecurityPermission(System.Security.Permissions.SecurityAction.Assert, UnmanagedCode = true)]
        public VisualWebPart1()
        {
        }
        protected override void OnInit(EventArgs e)

        {
            base.OnInit(e);InitializeControl();
        }
        protected void Page_Load(object sender, EventArgs e)
        {
            TextBox1.Focus();
        }
        protected void Button1_Click(object sender, EventArgs e)
        {
            if (string.IsNullOrEmpty(TextBox1.Text) || string.IsNullOrEmpty(TextBox2.Text) || string.IsNullOrEmpty(TextBox3.Text))
            {
                Label4.Text = "Please Enter Some Values";
                Label4.ForeColor = System.Drawing.Color.Red;
            }
            else
            {
                SPWeb web = SPContext.Current.Web;
                SPList list = web.Lists[TextBox1.Text];
                SPListItem item = list.GetItemById(int.Parse(TextBox3.Text));
                item.File.CheckOut();
                item["Name"] = TextBox2.Text;item.Update();
                item.File.CheckIn("File Name Change to " + TextBox2.Text, SPCheckinType.MinorCheckIn);
                TextBox1.Text = string.Empty;
                TextBox2.Text = string.Empty;

            }
        }
    }
