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)

public static IQueryable<TSource> Take<TSource>(
	this IQueryable<TSource> source,
	int count

Type Parameters


The type of the elements of source.


Type: System.Linq.IQueryable<TSource>

The sequence to return elements from.

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. For more information, see Extension Methods (Visual Basic) or Extension Methods (C# Programming Guide).


source is null.

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.

int[] grades = { 59, 82, 70, 56, 92, 98, 85 };

// Sort the grades in descending order and take the first three.
IEnumerable<int> topThreeGrades =
    grades.AsQueryable().OrderByDescending(grade => grade).Take(3);

Console.WriteLine("The top three grades are:");
foreach (int grade in topThreeGrades)

    This code produces the following output:

    The top three grades are:

Windows 7, Windows Vista, Windows XP SP2, Windows Server 2008 R2, Windows Server 2008, Windows Server 2003
