TFS Service Development: Set ChangedBy field for workitem

Case: You are developing service, that should change some WorkItems in Team Foundation Server.

Service should set field ChangedBy properly.

var collection1 = new TfsTeamProjectCollection(new Uri("http://tfs:8080/tfs/collection"));

collection1.EnsureAuthenticated();

var ims = collection1.GetService<IIdentityManagementService>();

var id = ims.ReadIdentity(IdentitySearchFactor.AccountName, "domain\\username", MembershipQuery.None, ReadIdentityOptions.None);

var collection = new TfsTeamProjectCollection(new Uri("http://tfs:8080/tfs/collection"), id.Descriptor);

-- OR --

WorkItem wi;

...

// Change Work Item

...

// Set ChangedBy Field

wi[CoreField.ChangedBy] = userName;

wi.Save();

How to convert TFS folder to branch programmatically by TFS API (Convert to Branch operation in VS2010))

How to convert TFS folder to branch programmatically by TFS API (Convert to Branch operation in VS2010))

First you need create instance of VersionControlServer object. Then use CreateBranchObject method. serverTrunkPath="C:\myWorkspace\trunk" - target folder you want to make branch.

versionControlServer.CreateBranchObject(new BranchProperties(new ItemIdentifier(serverTrunkPath)));

Select filename from file path

To get file name from file path by Regex:

string file = Regex.Match(FilePath, @"(?<=([\\/]))([^\\/])*?$").Value;

Example:

FilePath="/UI/Pages/WorkItems/QueryExplorer.aspx"

file="QueryExplorer.aspx"

Convert files from Dos to Unix and back.

        private void Unix2Dos(string fileName)

        {

            const byte CR = 0x0D;

            byte[] DOS_LINE_ENDING = new byte[] { CR, LF };

                int position = 0;

                int index = 0;

                do

                {

                    index = Array.IndexOf<byte>(data, LF, position);

                    if (index >= 0)

                    {

                        if ( ( index > 0 ) && (data[index - 1] == CR ))

TFS: To make merge from stablility or build Label to trunk

For example, you have code labelled "Stable_1" in development branch and you need to merge the code to trunk.

string SourceLabel = "Stable_1"

GetStatus status = workspace.Merge

    (DevelopmentPath, TrunkPath,

    null, VersionSpec.ParseSingleSpec( "L" + SourceLabel, null ),

    LockLevel.CheckOut, RecursionType.Full, MergeOptions.None);
