c# - SharpSVN - How to get the previous revision? -


i trying find efficient way previous revision of file text comparison using sharpsvn.

using (svnclient c = new svnclient()) {     c.authentication.defaultcredentials = new networkcredential(           configurationmanager.appsettings.get("svnserviceusername")         , configurationmanager.appsettings.get("svnservicepassword")         , configurationmanager.appsettings.get("svnservicedomain")         );     c.authentication.sslservertrusthandlers += new eventhandler<svnsslservertrusteventargs>(authentication_sslservertrusthandlers);      collection<svnfileversioneventargs> fileversioncollection = new collection<svnfileversioneventargs>();     svnrevisionrange range = new svnrevisionrange(0, this.hooks.revision);     svnfileversionsargs args = new svnfileversionsargs();     args.retrieveproperties = true;     args.range = range;      foreach (svnchangeitem item in log.changedpaths)     {         string path = this.repositorypath + item.path;          bool gotfileversions = false;          try         {             if (item.nodekind == svnnodekind.file)                 gotfileversions = c.getfileversions(svntarget.fromstring(path), args, out fileversioncollection); 

the code above example of performing request, extremely inefficient. goal able select revision, , previous revision. example, if repository @ r185, want view file @ revision 100, , view same file's previous revision (which wouldn't know is), how can done?

i've looked @ c.getinfo() seems previous revision current commit.

thanks!

try getting versions you're looking for. i'm assuming log instance of svnloggingeventargs?

if so, use:

args.range = new svnrevisionrange(log.revision, log.revision - 1); 

that way you'll retrieve changes revision, , because log.revision guaranteed revision number of change, if subtract one, have previous version.
