List all files changed under an Iteration

TL;DR; Shows how to use TFS API calls to list all files changed in a specific iteration, including querying work items and extracting changesets to a text file.

I was asked by a colleague to provide a list of all files that were changed under a particular iteration. Rather than delving into the data, I made a couple of API calls to TFS to output a text file with the list.

This is probably not the most efficient method and it is hard coded, but it does output the goods:

 1Dim tfs As New TeamFoundationServer("http://testtfs01:8080")
 2Dim store As WorkItemStore = tfs.GetService(GetType(WorkItemStore))
 3Dim version As VersionControlServer = tfs.GetService(GetType(VersionControlServer))
 4' Query for work items
 5Dim query As String = "SELECT [System.Id], [System.Title] " _
 6                     & "FROM WorkItems " _
 7                     & "WHERE [System.TeamProject] = @Project  " _
 8                     & "AND  [System.IterationPath] UNDER @IterationPath  " _
 9                     & "ORDER BY [System.Id]"
10Dim paramiters As New Hashtable
11paramiters.Add("Project", "TestProject1")
12paramiters.Add("IterationPath", "TestProject1TestIteration1")
13Dim y As WorkItemCollection = store.Query(query, paramiters)
14Console.WriteLine(String.Format("Found {0} work items", y.Count))
15' Query work items for attachments
16Dim wiats = From wi As WorkItem In y, l As Link In wi.Links Where l.BaseType = BaseLinkType.ExternalLink Select l, wi
17Console.WriteLine(String.Format("Loading {0} changesets...", wiats.Count))
18Dim ChangeSets As New List(Of Changeset)
19If Not wiats Is Nothing Then
20    Dim els = From i In wiats Where LinkingUtilities.DecodeUri(CType(i.l, ExternalLink).LinkedArtifactUri).ArtifactType = "Changeset"
21    For Each i In wiats
22        Dim el As ExternalLink = CType(i.l, ExternalLink)
23        Dim artifact As ArtifactId = LinkingUtilities.DecodeUri(el.LinkedArtifactUri)
24        If artifact.ArtifactType = "Changeset" Then
25            Dim cs As Changeset = version.ArtifactProvider.GetChangeset(New Uri(el.LinkedArtifactUri))
26            ChangeSets.Add(cs)
27        End If
28    Next
29    ' ------------------------------
30    Console.WriteLine(String.Format("{0} changesets loaded", ChangeSets.Count))
31    Dim files = From f In ChangeSets, c In f.Changes Select c.Item Distinct
32    Using x = System.IO.File.CreateText("c:Tempfiles.txt")
33        For Each f In files
34            x.WriteLine(f.ServerItem)
35        Next
36
37    End Using
38
39End If
40If Debugger.IsAttached Then
41    Console.ReadKey()
42End If

As you can see I have very bad naming and layout, but this is a one time use version of the code, so quick and dirty. If I am asked to do this again I would create a proper command line utility, or even a WPF interface to display the data prettily.
