I had some free time recently and so I wrote a wrapper for glandu's RpzRdbBase library so that it can be used in .Net applications.
To use the wrapper you will need:
Or you can compile form the source. Included in the source is a test application written in C# demoing how to use the wrapper.
The Database class is used to handle loading the rdb database dll and reading and writing the rdb. The class constructor takes a string parameter for the database dll (Ex: String81Database.dll) with or without .dll.
The RowManipulator class is used for reading data from the rdb file. The class constructor takes a Database instance.
