SharpSVN：无法连接到URL的存储库

Question

我正在尝试在C＃中编写一个SVN挂钩，用于确定事务被提交的分支。虽然不太可能并且违反常识，但我仍然想知道所涉及的所有分支。那部分效果很好。我遇到的问题是，如果我通过TortoiseSVN或VisualSVN Server在我的本地机器上使用本地存储库调试我的程序，它按预期工作。现在我将我的钩子移动到实际的服务器，我得到以下异常：

Unable to connect to a repository at URL 'file:///D:/SvnRepos/test'
at SharpSvn.SvnClientArgs.HandleResult(SvnClientContext client, SvnException error, Object targets)
at SharpSvn.SvnClientArgs.HandleResult(SvnClientContext client, svn_error_t* error, Object targets)
at SharpSvn.SvnClient.InternalLog(ICollection`1 targets, Uri logRoot, SvnRevision altPegRev, SvnLogArgs args, EventHandler`1 logHandler)
at SharpSvn.SvnClient.Log(Uri target, SvnLogArgs args, EventHandler`1 logHandler)
...
Unable to open an ra_local session to URL

我的代码：

HashSet<string> branches = new HashSet<string>();
// connect to SVN server
using (SvnClient client = new SvnClient())
{
    client.Authentication.Clear(); // Clear predefined handlers
    // authentication
    if (Credentials != null)
    {
        client.Authentication.UserNamePasswordHandlers
            += delegate(object obj, SharpSvn.Security.SvnUserNamePasswordEventArgs args)
            {
                args.UserName = Credentials.UserName;
                args.Password = Credentials.Password;
            }; 
        client.Authentication.SslServerTrustHandlers += delegate(object sender, SvnSslServerTrustEventArgs e)
        {
            e.AcceptedFailures = e.Failures;
            e.Save = true; // Save acceptance to authentication store
        };
    }
    client.Log(
        // ... of the specified repository ...
        repository,
        // ... and revision.
        new SvnLogArgs(new SvnRevisionRange(revision, revision)),
        // since only one revision is affected, a single set of log events is called
        (o, e) =>
        {
            if (e.ChangedPaths != null)
            {
                foreach (var p in e.ChangedPaths)
                {
                    ...
                }
            }
            else throw new NoChangedPathsException("List of changed paths could not be retrieved.");
        });
}

return branches.ToArray<string>();

我知道这里有类似的问题，我尝试了所有建议的解决方案;没人工作。感谢帮助。
