The complete code of visualwebpart1usercontrol.ascx looks like this:

<%@ Assembly Name="$SharePoint.Project.AssemblyFullName$" %>
<%
@ Assembly Name="Microsoft.Web.CommandUI, Version=14.0.0.0, Culture=neutral, PublicKeyToken=71e9bce111e9429c" %>

    Inherits="DocumentSetApp.VisualWebPart1.VisualWebPart1" %>
<center>
    <div>
        <table style="text-align: center">
            <tr>
                <td colspan="2">
                    <asp:label id="Label1" runat="server" text="DocumentSet  - SharePoint 2010 Programatically using VS 2012"
                        font-bold="true" font-size="Large" font-names="Verdana" forecolor="Maroon"></asp:label>
                </td>
            </tr>
            <tr>
                <td>
                    <asp:label id="Label2" runat="server" text="Please Enter List Name" font-size="Large"
                        font-names="Verdana" font-italic="true"></asp:label>
                </td>
                <td>
                    <asp:textbox id="TextBox1" runat="server"></asp:textbox>
                </td>
            </tr>
            <tr>
                <td>
                    <asp:label id="Label3" runat="server" text="Please Enter DocumentSet Name" font-size="Large"

                <td>
                    <asp:textbox id="TextBox2" runat="server"></asp:textbox>
                </td>
            </tr>

            <tr>

                <td colspan="2">

                    <asp:button id="Button1" runat="server" text="Create Document Set" font-names="Verdana"

                        width="174px" backcolor="Orange" font-bold="True" onclick="Button1_Click" />

                </td>

            </tr>

            <tr>

                <td colspan="2">

                    <asp:label id="Label5" runat="server" font-bold="true" font-names="Verdana"></asp:label>

                </td>

            </tr>
        </table>
    </div>
</center>

Step 5

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

using Microsoft.Office.DocumentManagement.DocumentSets;
using
Microsoft.SharePoint;
using
System;
using
System.Collections;
using
System.ComponentModel;
using
System.Web.
I.WebControls.WebParts;

namespace
DocumentSetApp.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))
            {
                Label5.Text = "Please Enter Some Values"; Label5.ForeColor = System.Drawing.Color.Red;
            }
            else
            {
                try
                {
                    SPWeb web = SPContext.Current.Web; SPList list = web.Lists[TextBox1.Text];
                    if (list != null)
                    {
                        SPContentType contentType = web.ContentTypes["Document Set"];
                        if (contentType != null)
                        {
                            var hashTable = new Hashtable();
                            hashTable.Add("DocumentSet", "New Doc Setting"); hashTable.Add("CreatedBy", SPContext.Current.Web.CurrentUser.Name);
                            hashTable.Add("ModifiedBy", SPContext.Current.Web.CurrentUser.Name);
                            DocumentSet documentSet = DocumentSet.Create(list.RootFolder, TextBox2.Text, contentType.Id, hashTable,true);
                            documentSet.Item.ProgId = "SharePoint.DocumentSet"; documentSet.Item.Update();
                        }
                    }
                }
                catch (SPException ex)
                {
                    Label5.Text = ex.Message;
                }
                Label5.Text = TextBox2.Text + " Document Set Created Successfully";
                Label5.ForeColor = System.Drawing.Color.Green;
                TextBox1.Text = string.Empty;
                TextBox2.Text = string.Empty;
            }
        }
    }
}

Step 6

Deploy the solution file and add the created webpart to SharePoint site.

Step 7

The output of the application looks like this:
