static member Where : System.Data.EnumerableRowCollection<'Row> * Func<'Row, bool> -> System.Data.EnumerableRowCollection<'Row>
<Extension()>
Public Function Where(Of TRow) (source As EnumerableRowCollection(Of TRow), predicate As Func(Of TRow, Boolean)) As EnumerableRowCollection(Of TRow)
Type Parameters

The type of the row elements in source
, typically DataRow.

An OrderedEnumerableRowCollection<TRow> that contains rows from the input sequence that satisfy the condition.
Remarks
This method is implemented by using deferred execution. The immediate return value is an object that stores all the information that is required to perform the action. The query represented by this method is not executed until the object is enumerated either by calling its GetEnumerator
method directly or by using foreach
in Visual C# or For Each
in Visual Basic.
