# DbDataReader Streaming Serialization > A C# serialization layer that streams DbDataReader results directly to JSON or XML through typed getters, avoiding DataTable/DTO materialization and resolving stable schema metadata once. - Author: Muhammet Ali Köker - Language: en - Canonical: https://alikoker.com.tr/en/db-reader-streaming-serialization-csharp - Translation: https://alikoker.com.tr/db-reader-streaming-serialization-csharp - Published: 2020-07-03T15:27:00+03:00 - Modified: 2026-08-27T10:36:29+03:00 - Verified: 2026-08-27T10:36:29+03:00 - Type: project The optimisation target here is the data path around serialization, not merely the serializer call itself. Materializing a large result set into a `DataTable`, a `List` or dictionaries creates an intermediate object graph that then has to be walked again. This implementation connects `DbDataReader` directly to `Utf8JsonWriter` or `XmlWriter`. Column names, type decisions and other stable schema information are prepared before the repeated row path. JSON names can be pre-encoded and common CLR types use typed getters. `DbRowView` deliberately reuses one view object as the reader advances instead of allocating a wrapper per row; consumers therefore must not retain it as if it were an immutable snapshot. Very large LOB values are a separate problem. The scalar path is not advertised as a replacement for provider-level `GetStream` or `GetTextReader` access. A related design principle appears in [CSV Enumerable](/en/csv-enumerable-csharp), where header/property mapping is also performed once before streaming rows.
