DataRowExtensions Group

The DataRowExtensions group contains extension methods that operate on IDataRow. These helpers make it easier to create rows based on column metadata, enumerate values, copy values from POCO objects, convert between IDataRow and POCO objects/interfaces, and merge refreshed row data into an existing row using a configurable merge strategy.

Purpose of DataRowExtensions

• Simplify creation of IDataRow instances that are consistent with a given schema (column metadata).
• Provide convenient methods to read field values by column name with optional type conversion.
• Support integration with POCO models: import values from POCO objects and export row values to POCO objects.
• Support synchronization scenarios at the row level (merging refreshed values into the current row).

Typical Capabilities

• Create new rows from a list of IColumnMetadata, initializing fields to null or to metadata-based default values.
• Enumerate all field name/value pairs for diagnostics, logging, or general-purpose mapping.
• Copy values from a POCO instance into a row using matching property/column names.
• Convert a row to a detached POCO object (ToPoco) or to a live interface proxy (AsInterface).
• Merge a refreshed row into the current row using the merge strategy configured in IMergeOptions.

Notes

• AsInterface returns a live proxy. Property reads / writes are forwarded to the underlying row.
• ToPoco returns a detached object. Changes to the returned POCO are not propagated back to the row.
• UpdateDataFieldValue is obsolete. Prefer using the row indexer directly (for example: dataRow["Name"] = "HR";).

When to Use These Extensions

Use DataRowExtensions whenever you need to treat IDataRow as a lightweight, schema-driven record that can still map naturally to strongly typed objects. These extensions are especially useful in dynamic UI scenarios and in mapping layers between DataSet-based processing and domain-specific models.
