generic <typename TRow>
 where TRow : System::Data::DataRow[System::Runtime::CompilerServices::Extension]
 static System::Data::EnumerableRowCollection<TRow> ^ Where(System::Data::TypedTableBase<TRow> ^ source, Func<TRow, bool> ^ predicate);

public static System.Data.EnumerableRowCollection<TRow> Where<TRow>(this System.Data.TypedTableBase<TRow> source, Func<TRow,bool> predicate) where TRow : System.Data.DataRow;

static member Where : System.Data.TypedTableBase<'Row (requires 'Row :> System.Data.DataRow)> * Func<'Row, bool (requires 'Row :> System.Data.DataRow)> -> System.Data.EnumerableRowCollection<'Row (requires 'Row :> System.Data.DataRow)> (requires 'Row :> System.Data.DataRow)

<Extension()>
Public Function Where(Of TRow As DataRow) (source As TypedTableBase(Of TRow), predicate As Func(Of TRow, Boolean)) As EnumerableRowCollection(Of TRow)

Type Parameters

TRow

The type of the row elements in source, DataRow.

Parameters

source: TypedTableBase<TRow>

A TypedTableBase<T> that contains the DataRow elements to filter.

predicate: Func<TRow,Boolean>

A function to test each element for a condition.

Returns

EnumerableRowCollection<TRow>
