How to export TFS changeset files to a destination Folder

Question

I want to export TFS source files of a particular changeset and/or multiple changesets in a series. Files should be exported to say D:\myTFSExport folder. This is not the existing mapped folder.

The purpose: I want to extract and review the CODEs of Build that contains these changesets after the Code are uploaded into TFS.

The following command of TFS Power Tool does not have any option for mentioning Destination folder.

tfpt getcs /changeset:changesetNo

Thanks in advance

How to extract a list of changesets

I had exactly this requirement in order to create patches for releases. I couldn't find anything in tfs or tfs power tools to do this, so I wrote my own.

To use, the syntax is a follows:

GetTfsChangeSet.exe TfsServerUrl changsetIdList fileOutputPath [merge]

where:

• TfsServerUrl: The TFS server Url
• changsetIdList : comma separated list of changesets
• fileOutputPath: Output path (does not need to be mapped)
• merge: With Merge param, combines all changesets into one folder. Without the param, each change set is output to a different folder.

e.g.

GetTfsChangeSet.exe http://asdpwiap017:8080/tfs 1233,4555,3332 c:\deploy merge

Create a console application solution.

Add these assembly references:

• Microsoft.TeamFoundation.Client
• Microsoft.TeamFoundation.Common
• Microsoft.TeamFoundation.VersionControl.Client

Program.cs

using System;
using System.Collections.Generic;
using System.IO;
using System.Linq;
using System.Text;
using Microsoft.TeamFoundation.Client;
using Microsoft.TeamFoundation.VersionControl.Client;

namespace GetTfsChangeSet
{
    class Program
    {
        static void Main(string[] args)
        {

            if (args.Length < 3)
            {
                Console.WriteLine("Usage:");
                Console.WriteLine("GetTfsChangeSet.exe TfsServerUrl changsetIds fileOutputPath [merge]");
                Console.WriteLine();
                Console.WriteLine("where:");
                Console.WriteLine("- changsetIdList : comma separated list of changesets");
                Console.WriteLine("- merge: With Merge param, combines all changesets into one folder. Without the param, each change set is output to a different folder.");
                Console.WriteLine();
                Console.WriteLine("e.g.");
                Console.WriteLine(@"GetTfsChangeSet.exe http://asdpwiap017:8080/tfs 1233,4555,3332 c:\deploy merge");

            string teamProjectCollectionUrl = args[0]; // "http://asdpwiap017:8080/tfs";
            var changesets = args[1].Split(',');
            string outputDir = args[2];
            bool mergeChangeSets = args.Length >= 4 && args[3].ToLower().Equals("merge");

            if (mergeChangeSets)
            {
                Console.WriteLine("Merge changesets " + args[1]);
            }

            TfsTeamProjectCollection teamProjectCollection = TfsTeamProjectCollectionFactory.GetTeamProjectCollection(new Uri(teamProjectCollectionUrl));
            string downloadPath = "";

            if (mergeChangeSets)
            {
                downloadPath = args[1].Replace(',', '-');
                if (downloadPath.Length > 30)
                {
                    downloadPath = downloadPath.Substring(0, 15) + "..." + downloadPath.Substring(downloadPath.Length-15);
                }
                downloadPath = Path.Combine(outputDir, downloadPath);

                Console.WriteLine(string.Format("ChangeSet {0}: {1} files extracted.", changeset, files.Count));
            }

            Console.WriteLine("Done.");
            //Console.ReadKey();

        private static List<string> GetFilesAssociatedWithBuild(TfsTeamProjectCollection teamProjectCollection, int changesetId, string downloadPath)
        {
            List<string> files = new List<string>();
            VersionControlServer versionControlServer = teamProjectCollection.GetService(typeof(VersionControlServer)) as VersionControlServer;
            Changeset changeset = versionControlServer.GetChangeset(changesetId);
            if (changeset.Changes != null)
