IInsertDataSyntax Rows(IEnumerable)

The idea is to turn this:

Insert.IntoTable("TableName")
.Row(new { SomeColumn = "test1" })
.Row(new { SomeColumn = "test2" });

into this:

Insert.IntoTable("TableName")
.Rows(new [] {
  { SomeColumn = "test1" },
  { SomeColumn = "test2" }
});

The actual use case? Piping CsvHelper GetRecords<T>() results directly into Insert.IntoTable("TableName").Rows(csvReader.GetRecords<T>()

[Migration(1)]
public class M1_MigrationTest : ForwardOnlyMigration
{
  public void Up()
  {
     CsvHelper.Configuration.CsvConfiguration config = new CsvHelper.Configuration.CsvConfiguration();
     config.RegisterClassMap<PersonRecordMap>();

     using (var reader = new CsvHelper.CsvReader(
        new System.IO.StreamReader(GetPersonDataAsEmbeddedResourceStream()),
        config))
     {
        Insert.IntoTable("Person").Rows(reader.GetRecords<PersonRecordMap>().ToList());
     }
  }

  private System.IO.Stream GetPersonDataAsEmbeddedResourceStream()
  {
    /* etc */
  }
}

Counter suggestion:

reader.GetRecords<PersonRecordMap>().
    .Aggregate((IInsertDataSyntax)Insert.IntoTable("Person"), (pv, item) => pv.Row(item))

OK, ok, definitely not as nice as having:

Insert.IntoTable("Person").Rows(reader.GetRecords<PersonRecordMap>().ToList());

IOW: I agree with this proposal.

Is it possible to use System.ComponentModel.DataAnnotations.Schema.ColumnAttribute? Or any other custom attribute with the same functionality will do.

Currently ExtractData(object) uses the name of a property, but it might be possible that the name of a column differs from the property name.

By the way, my implementation as an extension method:

public static IInsertDataSyntax Rows<T>(this IInsertDataOrInSchemaSyntax @this, IEnumerable<T> rows)
{
	var props = typeof(T).GetProperties()
		.ToImmutableDictionary(x => x.GetOneAttribute<ColumnAttribute>().Name ?? x.Name);

	foreach (var row in rows)
	{
		var input = new Dictionary<string, object?>(props.Count);

		foreach (var (col, prop) in props)
			input.Add(col, prop.GetValue(row));

		@this.Row(input);
	}

	return @this;
}
