如果你需要在其它程序中访问 Subversion 版本信息，可以使用 SubWCRev 的 COM 接口。创建的对象名称是 SubWCRev.object，支持下述方法：
表 6.4. 支持 COM/自动化 方法
| 方法 | 描述 |
|---|---|
| .GetWCInfo | This method traverses the working copy gathering the revision information. Naturally you must call this before you can access the information using the remaining methods. The first parameter is the path. The second parameter should be true if you want to include folder revisions. Equivalent to the -f command line switch. The third parameter should be true if you want to include svn:externals. Equivalent to the -e command line switch. |
| .GetWCInfo2 | The same as GetWCInfo() but with a fourth parameter that sets the equivalent to the -E command line switch. |
| .Revision | The highest commit revision in the working copy. Equivalent to $WCREV$. |
| .Date | The commit date/time of the highest commit revision. Equivalent to $WCDATE$. |
| .Author | 最高提交版本的作者，也就是工作副本中最后提交修改的人。 |
| .MinRev | 最小的更新版本，在 $WCRANGE$ 中描述 |
| .MaxRev | 最大的更新版本，在 $WCRANGE$ 中描述 |
| .HasModifications | 若本地存在修改，就为真 |
| .HasUnversioned | 如果是未版本控制项目则为真 |
| .Url | Replaced with the repository URL of the working copy path used in GetWCInfo. Equivalent to $WCURL$. |
| .IsSvnItem | 如果项目在版本控制中，为真 |
| .NeedsLocking | 如果项目有属性设置，为真 |
| .IsLocked | 如果项目被锁定，为真 |
| .LockCreationDate | String representing the date when the lock was created, or an empty string if the item is not locked. |
| .LockOwner | String representing the lock owner, or an empty string if the item is not locked. |
| .LockComment | 锁定创建时输入的信息 |
下述例子显示了如何使用接口。

The following listing is an example on how to use the SubWCRev COM object from C#:
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");
}
