Subversion - Revisions-Nummer auslesen + SVN-Nr. in Programm-Version eintragen

Beschreibung:

Hier ist ein kleines Werkzeug für Subversion (SVN).
Es bezieht sich auf das Datenformat von Subversion 1.7 (SQLite).
Quellcode zum Auslesen des alten Formats findet man in  Reading the revision number of a local copy of a SVN repository.

Mein Code kann folgendes:



Auslesen der aktuellen Revisionsnummer:

C#-Code:

SvnTool.GetRevisionNumber(String svnDirectory)

Aktualisierung der Datei "ApplicationInfo.cs".
Dabei wird die letzte Stelle der Versionnummer durch die aktuelle SVN Revisionnummer ersetzt.
Ergebnis: Die Versionsnummer der Anwendung (oder Bibliothek) beinhaltet die SVN-Revisionsnummer (z.B. 1.0.0.0 wird zu 1.0.0.666)

C#-Code:

UpdateAssemblyInfo(String svnDirectory, String assemblyInfoPath)

Thanks to Wiktor Zychla, who published a demo code how to read out the the revision information from the Subversion database.
