Interface IMergeDataReader

Namespace

DocWright.MailMerge

Assembly

DocWright.MailMerge.dll

A forward-only cursor over merge records.

public interface IMergeDataReader

Remarks

Deliberately shaped like IDataReader without being it. DocWright takes no dependency on System.Data — not in this package and not anywhere it could pull one into core — so a host that wants to merge from a DataTable or a DbDataReader writes the four-member adapter in their assembly, where the reference already exists. That adapter is a dozen lines; the alternative is a framework dependency in every consumer.

Forward-only is the point, not a limitation: a merge walks records once, so a 10,000-record source never has to be materialized.
