Please follow the Parsing Rules example given in the data directory of the repository. Mapping Rules should follow below model class structure
public class MappingRules
{
public string Namespace { get; set; }
public List Mappings { get; set; }
}
public class MappingTable
{
public string NodeName { get; set; }
public string XPath { get; set; }
public IList Columns { get; set;}
}
public class MappingColumn
{
public int OrderNumber { get; set; }
public string NodeName { get; set; }
public string XPath { get; set; }
public string DataType { get; set; }
public int MinLength { get; set; }
public int MaxLength { get; set; }
public int fractionDigits { get; set; }
public int totalDigits { get; set; }
}
The given example is in json file. Suppose you want to store Parsing rules in Database. Now you need to override the ParsingRules class method DeserializeRules.
public class ParsingDatabaseRules : ParsingRules
{
public override void DeserializeRules()
{
//MapParsingRules is of type IList?
MapParsingRules = GetMyRulesFromDB();
}
}
