Programmatically create a subfolder in SharePoint 2010 list

I have a custom list named “Custom”. I have a folder called "2012" in the list. I need to add a subfolder inside "2012" folder.

In this blog you will see how to create a subfolder in the list using SharePoint Object Model.

Code Snippet:

 using System;using System.Collections.Generic;using System.Linq;using System.Text;using Microsoft.SharePoint;using System.Collections; namespace CreateSubfolder{    class Program    {        static void Main(string[] args)        {            using (SPSite site = new SPSite("http://serverName/sites/Vijai/"))            {                using (SPWeb web = site.OpenWeb())                {                    SPList list = web.Lists.TryGetList("Custom");                    if (list != null)                    {                        foreach (SPListItem item in list.Folders)                        {                            if (item.Title == "2012")                            {                                SPListItem newItem = list.AddItem(item.Folder.ServerRelativeUrl, SPFileSystemObjectType.Folder);                                newItem["Title"] = "2012SubFolder1";                                newItem.Update();                            }                        }                                           }                }            }        }    }}

A subfolder named "2012SubFolder1" is created successfully inside "2012" folder in the custom list.
