Programmaticaly checkin all documents in a document library

Today i wrote some small peace of code but it saved me a lot of (click) work. I uploaded 200 documents to a document library but all documents were checked out. I could do this boring job manualy but as a Sharepoint developer i wrote a quick console application to do the job.

This is the code (you can copy past it to you console application):

using System;
using System.Collections.Generic;
using System.Text;
using Microsoft.SharePoint;

namespace CheckinDocuments
{
class Program
{
static void Main(string[] args)
{
Console.WriteLine("Please fill in the web url : ");
string webUrl = Console.ReadLine();

Console.WriteLine("Please fill in the name of the document library : ");
string documentLibraryName = Console.ReadLine();

if (webUrl != "")
{
using (SPSite site = new SPSite(webUrl))
{

SPWeb web = site.OpenWeb();
SPFile file = null;

//select the correct document library
foreach (SPList list in web.Lists)
{
if (list.Title.ToLower() == documentLibraryName.ToLower())
{
//loop all files and checkin if needed
foreach(SPListItem item in list.Items)
{
try
{

file = item.File;

if (file != null)
{
if (file.CheckOutStatus != SPFile.SPCheckOutStatus.None)
{
file.CheckIn("some comment");
file.Update();
Console.WriteLine("File checked-in = " + file.Name);
}
}
}
catch (Exception ex)
{
Console.WriteLine("Could not check-in file = " + file.Name + " - ERROR = " + ex.ToString());
}
}
}
}
}
}
Console.WriteLine("All documents are checked in, press enter to finish this program.");
Console.ReadLine();
}
}
}
