TryParsePropValue() public method

This method provides the functionality to convert any object to the appropriate type for this mapper. The default behaviour only handles null values, empty strings and DBNull.Value and parses all three to null. This method should be overridden in subtypes to parse values to the type you want.
public TryParsePropValue ( object valueToParse, object &returnValue ) : bool
valueToParse object The value to be attempted to parse
returnValue object the parsed value, if parsing was successful
return bool
