Queryable.Skip<TSource> Method

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

Namespace:  System.Linq
Assemblies:   System.Linq.Queryable (in System.Linq.Queryable.dll)
  System.Core (in System.Core.dll)

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

Type Parameters

TSource

The type of the elements of source.

Parameters

source
Type: System.Linq.IQueryable<TSource>

An IQueryable<T> to return elements from.

count
Type: System.Int32

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

Return Value

Type: System.Linq.IQueryable<TSource>
An IQueryable<T> that contains elements that occur after the specified index in the input sequence.

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).

ExceptionCondition
ArgumentNullException

source is null.

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.

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.

            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
            */
