    Awesome, my c# project uses Subversion as a wiki content management system and we have always had to rely on wrapping the command line output for all svn interactions. It works fine except that the performance isn’t great and you have to do all the hard work getting data into a meaningful format.

    Good afternoon:
    I’ve been trying to get a grip on SharpSVN for the last couple of hours — your post has been helpful.
    I’m trying to write a script to get me out of a bind:
    Up till last week, I was using the original svnserve, and the svn://protocol, on my home IIS.
    Then I discovered VisualSVN Server, and liked the fact that I could finally show code pages on the web. So I made the switch.
    All’s good…except the EXTERNALS which I have to update from svn://…./repo/ to http://…:8080/svn/repo/ — and I have a LOT of them….just the perfect thing for a script rather than spend 5 days doing it by hand :-)
    The SharpSVN docs are ….pretty empty…so I can’t find a way to get the list of file names in a dir.
    Basically, what I’m thinking would be to:
    a) create a svnTarget pointing to root url
    b) get list of folders in that target
    c) look at properties…if svn:external, update
    d) recurse deeper…creating new Targets as I go.
    But after about 2 hours, trying GetInfo, etc. to get a list of the dir names/urls,
    all I am getting to work is GetNowhere…
    Would you be able to point me in the right direction?
    Thanks immensly!

    Without seeing any source code, I cannot help too much but I can give you some pointers. First, the best documentation for SharpSvn are the API docs, the tests and the AnkhSVN source base:
    Next, I’d do my work on a working copy to eliminate network activity for every file you check, and also so you can commit all changes at one time. That being said, here is a high level of steps I’d have in my application/script:
    1) Create a working copy.
    2) Create an SvnTarget for the WC root.
    3) Run SvnClient.GetPropertyList on WC.
    4) Resolve svn:externals on WC root if there are any.
    5) Run SvnClient.List to get a list of versioned objects in the WC.
    6) Iterate over each object and check for SvnListEventArgs.Entry.NodeKind to see if it’s a directory.
    7) When you find a dir, get its properties as mentioned above, fix and recurse into that directory and repeat steps 5-6.
    I think that should handle everything. Also, make sure to use SvnClient in a using block since it’s disposable. I hope this helps.
    Take care,

    This does not address your question, but I’d recommend you update to Subversion 1.5 (it sounds like you did). One of the features is “relative externals”. If you are going to change them all you might as well do so in a way that requires you to never have to update them again.
    You do need 1.5 clients to use this feature.

    Once I figured out how the Arguments were to be used (to setup the request)
    thinks started working better…
    //KEY PIECE OF INFO… Not evident :-)
    args.Depth = SvnDepth.Children;
    //Right…get info about the target:
    if (!_SVNClient.GetInfo(svnTarget, args, out outArgs)) {
    return false;
    int count = outArgs.Count;
    foreach (SvnInfoEventArgs e in outArgs) {

    The help docs, currently, are …to be frank…practically useless: your demo was far far better :-)
    Absolutly bloody marvelous the 1.5 relative externals… I did implement that for the first time, and for a second scratched my head looking at the error msg, because I didn’t notice the little paragraph at the bottom of the subversion 1.5 change.log that mentioned that the string entries are now flipped “relativePath localSubDir”
    All is working now…I just did a test run on some 3000 dirs…and they’ve checked out correctly (although…hum…visualSVN’s http protocol is quite a bit slower than native svn://) Oh well.
    I wasn’t sure if you would appreciate a long post here full of code showing the solution I used — so I posted it on my (VERY slow for now until I find a better hosting situation) site:
    In the hopes it helps someone later…
    Thanks again for both your help!

    I am trying to implement the Copy (Branch/Tag) function in with SharpSVN API (v1.4999.519).
    using (SvnClient svnClient = new SvnClient()) {
    System.Net.NetworkCredential cred = new System.Net.NetworkCredential(“username”, “password”);
    svnClient.Authentication.DefaultCredentials = cred;
    SvnCopyArgs arg = new SvnCopyArgs();
    arg.LogMessage = “SAC Build Manager – testing Tag”;
    SvnUriTarget target = new SvnUriTarget(new Uri(@”http://sacsvn01/repos/EnterpriseServices/LibForeign/i4o/″));
    On the svcClient.Copy line, I received this error:
    “This argument is not a valid path. A Uri was specifiedrnParameter name: toPath”
    I think the 2nd argument in the Copy method does not support URI path. Please advice

    I want use SVN server API in my application, and i don,t want use SNV client.
    please hlp me.

    Try SvnClient.RemoteCopy() to copy to a remote location. SharpSvn dictates that you should pass a Uri or SvnUriTarget when you need a remote location.
    Ordinary strings are always local paths.
    There is no real server api. Subversion only provides a few standard servers.
    The only public api on your repository server is the hooks api.
    The new SvnLookClient class in recent SharpSvn releases can help you writing hooks.

    I’m new to VB and SVN and involved in writing automation scripts in VBA. I’ve got a requirement where we need to ‘retrieve ,checkout ,add ‘ files to/from SVN remote repository from VB code in background as part of automation. Please can anyone guide me what needs to be done.
    Can I use sharpSVN / SVN command line.. ?

    If you have and wouldn’t mind to share it, I would like some c# source code which illustrates how to checkout single files using SharpSVN.
