AsIndexed Method
AsIndexed(DataTable)
Wraps a DataTable in an IndexedDataTable<DataRow> so it can be indexed and queried using the optimized query operators from IndexedQueryExtensions.
Declaration
public static IndexedDataTable<DataRow> AsIndexed(this DataTable table)Parameters
| Type | Name | Description |
|---|---|---|
| DataTable | table | A DataTable to represent as an IndexedDataTable<DataRow>. |
Returns
| Type | Description |
|---|---|
| IndexedDataTable<DataRow> | An IndexedDataTable<DataRow> that contains the same rows as table and enables indexing of its rows. |
Remarks
Use this method to index ADO.NET data tables and query them using the query operators optimized with indexing.
Elements of the source data table aren't duplicated or copied to a new collection. This method just wraps the original data table in an IndexedDataTable<DataRow>.
Note: The IndexedDataTable<DataRow> wrapper is owned by the original DataTable object (in fact, it is stored in its ExtendedProperties). So, if you create a wrapper for the same data table several times, it will be the same object.AsIndexed<TRow>(DataTable)
Wraps a DataTable in an IndexedDataTable<TRow> so it can be indexed and queried using the optimized query operators from IndexedQueryExtensions.
Declaration
public static IndexedDataTable<TRow> AsIndexed<TRow>(this DataTable table) where TRow : DataRowParameters
| Type | Name | Description |
|---|---|---|
| DataTable | table | A DataTable to represent as an IndexedDataTable<TRow>. |
Returns
| Type | Description |
|---|---|
| IndexedDataTable<TRow> | An IndexedDataTable<TRow> that contains the same rows as table and enables indexing of its rows. |
Type Parameters
| Name | Description |
|---|---|
| TRow | The type of the rows in the table. |

Wraps a typed ADO.NET data table in an IndexedDataTable<TRow> so it can be indexed and queried using the optimized query operators from IndexedQueryExtensions.
Declaration
public static IndexedDataTable<TRow> AsIndexed<TRow>(this TypedTableBase<TRow> table) where TRow : DataRowParameters
| Type | Name | Description |
|---|---|---|
| TypedTableBase<TRow> | table | A typed data table to represent as an IndexedDataTable<TRow>. |
Returns
| Type | Description |
|---|---|
| IndexedDataTable<TRow> | An IndexedDataTable<TRow> that contains the same rows as table and enables indexing of its rows. |
Type Parameters
| Name | Description |
|---|---|
| TRow | The type of the rows in the table. |
Remarks
Use this method to index typed data tables and query them using the query operators optimized with indexing.
