In This Topic
AsIndexed(DataTable) Method
In This Topic
Wraps a System.Data.DataTable in an IndexedDataTable<DataRow> so it can be indexed and queried using the optimized query operators from C1.LiveLinq.IndexedQueryExtensions.
Syntax

Public Overloads Shared Function AsIndexed( _
   ByVal table As System.Data.DataTable _
) As IndexedDataTable(Of DataRow)
 

Parameters

table
A System.Data.DataTable to represent as an IndexedDataTable<DataRow>.

Return Value

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 System.Data.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.
