Queryable::Take<TSource> Method

Returns a specified number of contiguous elements from the start of a sequence.

Namespace:  System.Linq
Assembly:  System.Core (in System.Core.dll)

No code example is currently available or this language may not be supported.

Type Parameters

TSource

The type of the elements of source.

Parameters

source
Type: System.Linq::IQueryable<TSource>
The sequence to return elements from.
count
Type: System::Int32
The number of elements to return.

Return Value

Type: System.Linq::IQueryable<TSource>
An IQueryable<T> that contains the specified number of elements from the start of source.

Usage Note

In Visual Basic and C#, you can call this method as an instance method on any object of type IQueryable<TSource>. When you use instance method syntax to call this method, omit the first parameter.

ExceptionCondition
ArgumentNullException

source is nullptr.

The Take<TSource>(IQueryable<TSource>, Int32) method generates a MethodCallExpression that represents calling Take<TSource>(IQueryable<TSource>, Int32) itself as a constructed generic method. It then passes the MethodCallExpression to the CreateQuery(Expression) method of the IQueryProvider represented by the Provider property of the source parameter.

The query behavior that occurs as a result of executing an expression tree that represents calling Take<TSource>(IQueryable<TSource>, Int32) depends on the implementation of the type of the source parameter. The expected behavior is that it takes the first count elements from the start of source.

The following code example demonstrates how to use Take<TSource>(IQueryable<TSource>, Int32) to return elements from the start of a sequence.
