Queryable.Skip<TSource>(IQueryable<TSource>, Int32) Method

Definition

Bypasses a specified number of elements in a sequence and then returns the remaining elements.

C#
public static System.Linq.IQueryable<TSource> Skip<TSource>(this System.Linq.IQueryable<TSource> source, int count);

Type Parameters

TSource

The type of the elements of source.

Parameters

source
IQueryable<TSource>

An IQueryable<T> to return elements from.

count
Int32

The number of elements to skip before returning the remaining elements.

Returns

IQueryable<TSource>

An IQueryable<T> that contains elements that occur after the specified index in the input sequence.

Exceptions

source is null.

Examples

The following code example demonstrates how to use Skip<TSource>(IQueryable<TSource>, Int32) to skip a specified number of elements in a sorted array and return the remaining elements.

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

// Sort the grades in descending order and
// get all except the first three.
IEnumerable<int> lowerGrades =
    grades.AsQueryable().OrderByDescending(g => g).Skip(3);

Console.WriteLine("All grades except the top three are:");
foreach (int grade in lowerGrades)
    Console.WriteLine(grade);

/*
    This code produces the following output:

    All grades except the top three are:
    82
    70
    59
    56
*/

Remarks

The Skip<TSource>(IQueryable<TSource>, Int32) method generates a MethodCallExpression that represents calling Skip<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 Skip<TSource>(IQueryable<TSource>, Int32) depends on the implementation of the type of the source parameter. The expected behavior is that it skips the first count elements in source and returns the remaining elements.
