}dotnet add package RDBParse
- Implement your own
IReaderCallback - Create a new instance of
BinaryReaderRDBParser - Call Parse method of
BinaryReaderRDBParserinstance
Following this below code for example.
public class MyReaderCallBack : IReaderCallback
{
}var path = "/yourpath/your.rdb"
var cb = new MyReaderCallBack();
var parser = new RDBParser.BinaryReaderRDBParser(cb);
parser.Parse(path);Contributions are welcome!
