在使用版本控制系統時，若是想要查詢異動紀錄，唯一的辦法就是開啟 Visual Studio 進入原始檔控制總管，然後點選專案再選取檢視紀錄。雖然這樣已經很方便了，但若是要進行註解的搜尋就會有些麻煩了。

基於此原因，就想到將變更紀錄匯出，就可以快速進行註解的搜尋了。

使用參考：

Microsoft TeamFoundationServer ExtendedClient

Dapper

 

首先透過

TfsTeamProjectCollection teamProjects = new TfsTeamProjectCollection(new Uri(<TFS Server 網址>));

建立 TFS Client 端連線，接著取回版本控制服務

VersionControlServer vcsTFS = teamProjects.GetService<VersionControlServer>();

在版控服務中可以取回所有專案的名稱

var allProjectName = vcsTFS.GetAllTeamProjects(false).Select(x => x.Name).ToList();

取回指定專案的異動集資料

var allHistories = vcsTFS.QueryHistory("$/" + projectName, VersionSpec.Latest, 0, RecursionType.Full, null, null, null, int.MaxValue, true, false);

透過迴圈可以取得每一個異動集的資訊

foreach (Changeset history in allHistories)
{
    var changesetID = history.ChangesetId;  // 異動集的編號
    var Comment = history.Comment;  // 簽入的說明
    var Committer = history.Committer;  // 簽入的人員
    var CommitterDisplayName = history.CommitterDisplayName;  // 簽入人員名稱
    var CreationDate = history.CreationDate;  // 簽入日期
    var changes = history.Changes;  // 簽入的檔案資訊
}

其中 history.Changes 紀錄了所有簽入的檔案資訊

foreach (Change change in history.Changes)
{
    var ChangeType = change.ChangeType;  // 異動類別
    var CheckinDate = change.Item.CheckinDate;  // 簽入日期
    var ItemType = change.Item.ItemType;  // 項目類別
    var ServerItem = change.Item.ServerItem;  // 檔案路徑
}

若是要下載該項目，可以使用 change.Item.DownloadFile() 將檔案取回。
例：

byte[] bFile = new byte[change.Item.ContentLength];
change.Item.DownloadFile().Read(bFile, 0, (int)change.Item.ContentLength);

ChangeType 列舉：
1  = 無
2  = 新增
4  = 修改
8  = 編碼
16  = 更名
32  = 刪除
64  = 回復刪除
128  = 分支
256  = 合併
512  = 鎖定
1024 = RollBack
2048 = 來源更名
8192 = 屬性更改

ItemType 列舉：
0 = 其他
1 = 資料夾
2 = 檔案

程式碼：

private void Query_ProjectList()
{
		tpc = new TfsTeamProjectCollection(new Uri(txtURL.Text));
    vcs = tpc.GetService<VersionControlServer>();
    lstProjectData = vcs.GetAllTeamProjects(false).Select(x => new ProjectVM() { ProjectName = x.Name }).ToList();

    foreach (var tmp in lstProjectData)
    {
        int iItem = 0;
        List<Changeset> allHistory = vcs.QueryHistory("$/" + tmp.ProjectName, VersionSpec.Latest, 0, RecursionType.Full, null, null, null, int.MaxValue, true, false).Cast<Changeset>().ToList();
        tmp.ChangeCount = allHistory.Count();
        allHistory.ForEach(x => { iItem += x.Changes.Count(); });
        tmp.ChangeItemCount = iItem;
    }
}

private void Export_Project(string projectName)
{
    TfsTeamProjectCollection tpc = new TfsTeamProjectCollection(new Uri(txtURL.Text));
    VersionControlServer vcs = tpc.GetService<VersionControlServer>();
    var allHistories = vcs.QueryHistory("$/" + projectName, VersionSpec.Latest, 0, RecursionType.Full, null, null, null, int.MaxValue, true, false);

程式是運氣與直覺堆砌而成的奇蹟。
若不具備這兩者，不可能以這樣的工時實現這樣的規格。
修改規格是對奇蹟吐槽的褻瀆行為。
而追加修改則是相信奇蹟還會重現的魯莽行動。
