Filters a sequence of rows based on the specified predicate. This API supports the .NET Framework infrastructure and is not intended to be used directly from your code.
Assembly: System.Data.DataSetExtensions (in System.Data.DataSetExtensions.dll)
public static EnumerableRowCollection<TRow> Where<TRow>( this EnumerableRowCollection<TRow> source, Func<TRow, bool> predicate )
The type of the row elements in source, typically DataRow.
- Type: System.Data.EnumerableRowCollection<>
Return ValueType: System.Data.EnumerableRowCollection<>
An OrderedEnumerableRowCollection<TRow> that contains rows from the input sequence that satisfy the condition.
Usage NoteIn Visual Basic and C#, you can call this method as an instance method on any object of type EnumerableRowCollection<>. When you use instance method syntax to call this method, omit the first parameter. For more information, see Extension Methods (Visual Basic) or Extension Methods (C# Programming Guide).
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.
