如果您需要從其他程式存取 Subversion 版本資訊，您可以使用 SubWCRev 的 COM 介面。要建立的物件是 SubWCRev.object，並且支援下列方法
表格 6.4. 支援的 COM/自動化方法
| 方法 | 說明 |
|---|---|
| .GetWCInfo | 此方法會遍歷工作副本，收集版本資訊。理所當然地，您必須先呼叫此方法，才能使用其餘的方法存取資訊。第一個參數是路徑。如果您想要包含資料夾版本，第二個參數應該為 true。相當於 -f 命令列開關。如果您想要包含 svn:externals，第三個參數應該為 true。相當於 -e 命令列開關。 |
| .GetWCInfo2 | 與 GetWCInfo() 相同，但具有第四個參數，該參數設定相當於 -E 命令列開關。 |
| .Revision | 工作副本中最高的提交版本。相當於 $WCREV$。 |
| .Date | 最高提交版本的提交日期/時間。相當於 $WCDATE$。 |
| .Author | 最高提交版本的作者，也就是說，最後一位提交工作副本變更的人。 |
| .MinRev | 最小更新版本，如 $WCRANGE$ 中所示 |
| .MaxRev | 最大更新版本，如 $WCRANGE$ 中所示 |
| .HasModifications | 如果存在本機修改則為 True |
| .HasUnversioned | 如果存在未版本控制的項目則為 True |
| .Url | 替換為在 GetWCInfo 中使用的工作副本路徑的儲存庫 URL。相當於 $WCURL$。 |
| .RepoRoot | 替換為儲存庫根目錄的 URL。相當於 $REPOROOT$。 |
| .IsSvnItem | 如果項目已版本控制則為 True。 |
| .NeedsLocking | 如果項目已設定 svn:needs-lock 屬性則為 True。 |
| .IsLocked | 如果項目已鎖定則為 True。 |
| .LockCreationDate | 字串，表示鎖定建立的日期；如果項目未鎖定，則為空字串。 |
| .LockOwner | 字串，表示鎖定擁有者；如果項目未鎖定，則為空字串。 |
| .LockComment | 建立鎖定時輸入的訊息。 |
以下範例示範如何使用此介面。
// testCOM.js - javascript file
// test script for the SubWCRev COM/Automation-object

filesystem.GetAbsolutePathName("."), 1, 1);
revObject2.GetWCInfo(
filesystem.GetAbsolutePathName(".."), 1, 1);

revObject4.GetWCInfo2(
filesystem.GetAbsolutePathName("..\\.."), 1, 1, 1);

以下清單是一個範例，說明如何從 C# 使用 SubWCRev COM 物件
using LibSubWCRev;
SubWCRev sub = new SubWCRev();
sub.GetWCInfo("C:\\PathToMyFile\\MyFile.cc", true, true);
if (sub.IsSvnItem == true)
{
MessageBox.Show("versioned");
}
else
{
MessageBox.Show("not versioned");
}
