Hi Yosi,


I’m not sure how relevant the serf list is for this question. The users{_at_}@sharpsvn.open.collab.net is probably more appropriate unless you have a more specific error message pointing towards the ‘serf’ http library below Subersion.


Talking about the error message:

Can you send the complete error message instead of only the top level error? The easiest way to obtain would be to call .ToString() on the exception instead of the .Message.


Both Subversion and .Net use nested error messages to provide more details… In this case the message will tell you what failed on connecting to the repository: bad path, some server error, authentication, etc. etc.


You could iterate over .InnerException on each exception, but just calling .ToString() does all that and a bit more.



Another thing I usually try is replicating the problem with the commandline client. The Slik Subversion client is compiled with mostly the same compiler settings and dependencies as SharpSvn, so sometimes just using that client helps in finding a root cause.

Subject: please help - SharpSvn problem Question


Hello Bert,

How are you?


I am developing in C # with visual studio 2013,2015 and have a particular problem with SharpSvn and I hope you can solve it for me.


Installs and downloads:


I installed VisualSvnServer Version: 3.5.7 on a virtual server with the following settings:

Authentication tab - integrated windows authentication

Security tab - add permissions to my user (my user is administrator)

Certificate tab - change to my company certificate

Network tab - I use secure connection (https: //) with port 443

I add admin permission to the repository root


2. Client Side

TortoiseSVN 1.9.5, Build 27581-64 Bit

And AnkhSvn-2.6.12735


3. I downloaded the latest version of SharpSvn (SSvn-1.9005.3934.158-x64)


Problem Description:

When I'm trying to merge through the UI TortoiseSVN everything works fine and it perform the merge and the commit to the repository/

When I try to do this through C# code with SharpSvn I get a message "Unable to connect to a repository at URL 'https://MyServer.co.il/svn/noam2/Yosi/NorthwindTrunk2/Trunk'"

After call client.Merge(qa_work_copy, mergeFrom, revisionsRange, mergeArgs);

I think I tried everything:

I tried without Authentication of user and password

I tried Authentication of user and password via client.Authentication.ForceCredentials

I signed up for all the events of Authentication and some even not fired,

For example:




I even set the DefaultCredentials via System.Net.NetworkCredential(user, password) without any success


Incidentally, I am successful to perform the Update action using an SharpSvn


I enclose you snippets of code I wrote to those who succeeded and those that failed

I do not know what to do about it and the more I will be happy if you can help me solve this problem.
