Enumerable.Skip<TSource> Method

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

Namespace:  System.Linq
Assembly:  System.Core (in System.Core.dll)
public static IEnumerable<TSource> Skip<TSource>(
	this IEnumerable<TSource> source,
	int count
)

Type Parameters

TSource

The type of the elements of source.

Parameters

source
Type: System.Collections.Generic.IEnumerable<TSource>
An IEnumerable<T> to return elements from.
count
Type: System.Int32
The number of elements to skip before returning the remaining elements.

Return Value

Type: System.Collections.Generic.IEnumerable<TSource>
An IEnumerable<T> that contains the 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 IEnumerable<TSource>. When you use instance method syntax to call this method, omit the first parameter.
ExceptionCondition
ArgumentNullException

source is null.

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.

If source contains fewer than count elements, an empty IEnumerable<T> is returned. If count is less than or equal to zero, all elements of source are yielded.

The Take<TSource> and Skip<TSource> methods are functional complements. Given a sequence coll and an integer n, concatenating the results of coll.Take(n) and coll.Skip(n) yields the same sequence as coll.

In Visual Basic query expression syntax, a Skip clause translates to an invocation of Skip<TSource>.

The following code example demonstrates how to use Skip<TSource> 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 };

      IEnumerable<int> lowerGrades =
          grades.OrderByDescending(g => g).Skip(3);

      outputBlock.Text += "All grades except the top three are:" + "\n";
      foreach (int grade in lowerGrades)
      {
         outputBlock.Text += grade + "\n";
      }

      /*
       This code produces the following output:

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