Question

Is there a way to download specific TFS build log? we’re using TFS 2013.
I’ve already tried to use the IBuildDetail, yet failed.
THX.

You can use the menthod “Get Build”. It returns IBuildDetail , use IBuildDetail.LogLocation property to get the log file for this build. Finally download or query it. Below is a demo code:
publicstaticvoid GetBuildLogAndReadThroughTheLog()
{
// Get all the team projects using the TFS API
var tfs = TfsTeamProjectCollectionFactory.GetTeamProjectCollection(new Uri(ConfigurationManager.AppSettings["TfsUri"]));
var versionControlService = tfs.GetService<VersionControlServer>();
var teamProject = versionControlService.GetAllTeamProjects(false)[0];
// Use the build service to get build details for a team project
var buildService = tfs.GetService<IBuildServer>();
// Get the build details
var build = buildService.QueryBuilds(teamProject.Name)[0];
// Get the location of the build Log
var buildLogLocation = build.LogLocation;
// Get the log file
var logFile = versionControlService.GetItem(buildLogLocation);
// Do you want to download the file to a local path?
TextReader tr = new StreamReader(logFile.DownloadFile());
string input = null;
while ((input = tr.ReadLine()) != null)
{
}
}
}
The entire build log can be found in the Tfs_YourTeamProjectCollection database in the Tbl_BuildInformation. You can also query and get it from DataBase

UPdate
Using "StreamReader" will read the log file line by line.
using (StreamReader sr = new StreamReader(buildLogLocation)
{
while (sr.Peek() >= 0)
{
// do your work here...
}
}
