Previously, I described a Bencoding Library I made to simplify working with the Bencoding structure in .NET. I also published it on Codeplex. However, I discovered a flaw—if a string contains a null-byte (as most .torrent files do), it will fail. So I made a fix, which has been uploaded to Codeplex as changeset 1102.

As can be seen in the changeset, a few files have been changed. Ignoring all the test files, the changes were made to:

  • Base.cs
  • Bencode.String.cs

And that’s pretty much it. However, these changes are significant. The differences can be seen here:

The changes mainly involve treating strings as byte arrays, with helper conversions between string and byte array. The Decode() function has been overridden and now provides two methods: one using strings (as before) and another using a BinaryReader, which allows for reading strings containing null bytes.

And that’s it. :P
