如何从 SharpSVN 获取最新版本号？

Question

如何使用 SharpSVN 获取最新版本号？

Answer 1

从存储库检索头部修订的最便宜的方法
是信息命令。

using(SvnClient client = new SvnClient())
{
   SvnInfoEventArgs info;
   Uri repos = new Uri("http://my.server/svn/repos");

   client.GetInfo(repos, out info);

   Console.WriteLine(string.Format("The last revision of {0} is {1}", repos, info.Revision));
}

Answer 2

我正在使用 SvnWorkingCopyClient 检查工作副本的最新版本：

var workingCopyClient = new SvnWorkingCopyClient();

SvnWorkingCopyVersion version;

workingCopyClient.GetVersion(workingFolder, out version);

然后可以通过“

long localRev = version.End;

对于远程存储库，请使用

 var client = new SvnClient();

 SvnInfoEventArgs info;

 client.GetInfo(targetUri, out info);

 long remoteRev = info.Revision;

”来获得本地工作存储库的最新版本。

这类似于从命令行使用 svnversion 工具。 希望这可以帮助。

Answer 3

好吧，我自己想出来了：

SvnInfoEventArgs statuses;
client.GetInfo("svn://repo.address", out statuses);
int LastRevision = statuses.LastChangeRevision;

Answer 4

我也用谷歌搜索了很多，但唯一对我有用的事情是：

public static long GetRevision(String target)
    {
        SvnClient client = new SvnClient();

        //SvnInfoEventArgs info;
        //client.GetInfo(SvnTarget.FromString(target), out info); //Specify the repository root as Uri
        //return info.Revision
        //return info.LastChangeRevision

        Collection<SvnLogEventArgs> info = new Collection<SvnLogEventArgs>();
        client.GetLog(target, out info);
        return info[0].Revision;
    }

其他解决方案都被注释掉了。 亲自尝试一下，看看有什么不同。 。 。

Answer 5

好吧，快速的谷歌搜索给了我这个，并且它有效（只需指向 /trunk/ URI）：

Answer 6

这是一个很老的问题，上面两个答案已经很好地回答了。 尽管如此，希望对某人有所帮助，我发布了以下 C# 方法来说明如何不仅从存储库和工作副本中获取修订号，而且还说明了如何测试可能出现的典型情况被视为问题，例如在自动化构建过程中。

  /// <summary>
  /// Method to get the Subversion revision number for the top folder of the build collection, 
  /// assuming these files were checked-out from Merlinia's Subversion repository. This also 
  /// checks that the working copy is up-to-date. (This does require that a connection to the 
  /// Subversion repository is possible, and that it is running.)
  /// 
  /// One minor problem is that SharpSvn is available in 32-bit or 64-bit DLLs, so the program 
  /// needs to target one or the other platform, not "Any CPU".
  /// 
  /// On error an exception is thrown; caller must be prepared to catch it.
  /// </summary>
  /// <returns>Subversion repository revision number</returns>
  private int GetSvnRevisionNumber()
  {
     try
     {
        // Get the latest revision number from the Subversion repository
        SvnInfoEventArgs svnInfoEventArgs;
        using (SvnClient svnClient = new SvnClient())
        {
           svnClient.GetInfo(new Uri("svn://99.99.99.99/Merlinia/Trunk"), out svnInfoEventArgs);
        }

        // Get the current revision numbers from the working copy that is the "build collection"
        SvnWorkingCopyVersion svnWorkingCopyVersion;
        using (SvnWorkingCopyClient svnWorkingCopyClient = new SvnWorkingCopyClient())
        {
           svnWorkingCopyClient.GetVersion(_collectionFolder, out svnWorkingCopyVersion);
        }

        // Check the build collection has not been modified since last commit or update
        if (svnWorkingCopyVersion.Modified)
        {
           throw new MerliniaException(0x3af34e1u, 
                  "Build collection has been modified since last repository commit or update.");
        }

        // Check the build collection is up-to-date relative to the repository
        if (svnInfoEventArgs.Revision != svnWorkingCopyVersion.Start)
        {
           throw new MerliniaException(0x3af502eu, 
             "Build collection not up-to-date, its revisions = {0}-{1}, repository = {2}.",
             svnWorkingCopyVersion.Start, svnWorkingCopyVersion.End, svnInfoEventArgs.Revision);
        }

        return (int)svnInfoEventArgs.Revision;
     }
     catch (Exception e)
     {
        _fLog.Error(0x3af242au, e);
        throw;
     }
  }

（此代码确实包含一些特定于从中复制的程序的内容，但这不应使 SharpSvn 部分难以理解。）
