How to access the current Subversion build number?

Question

How can you automatically import the latest build/revision number in subversion?

The goal would be to have that number visible on your webpage footer like SO does.

Answer 1

Add svn:keywords to the SVN properties of the source file:

svn:keywords Revision

Then in the source file include:

private const string REVISION = "$Revision$";

The revision will be updated with the revision number at the next commit to (e.g.) "$Revision: 4455$". You can parse this string to extract just the revision number.
