Type Parameters
- TSource
The type of the elements of source.
Usage Note
In Visual Basic and C#, you can call this method as an instance method on any object of type IEnumerable<(Of <(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 nullNothingnullptra null reference (Nothing in Visual Basic). |
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<(Of <(T>)>) is returned. If count is less than or equal to zero, all elements of source are yielded.
The Take<(Of <(TSource>)>) and Skip<(Of <(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<(Of <(TSource>)>).
The following code example demonstrates how to use Skip<(Of <(TSource>)>) to skip a specified number of elements in a sorted array and return the remaining elements.
' Create an array of integers that represent grades.
Dim grades() As Integer = {59, 82, 70, 56, 92, 98, 85}
' Sort the numbers in descending order and
' get all but the first (largest) three numbers.
Dim lowerGrades As IEnumerable(Of Integer) = _
grades _
.OrderByDescending(Function(g) g) _
.Skip(3)
' Display the results.
Dim output As New System.Text.StringBuilder("All grades except the top three are:" & vbCrLf)
For Each grade As Integer In lowerGrades
output.AppendLine(grade)
Next
MsgBox(output.ToString())
' This code produces the following output:
'
' All grades except the top three are:
' 82
' 70
' 59
' 56
int[] grades = { 59, 82, 70, 56, 92, 98, 85 };
IEnumerable<int> lowerGrades =
grades.OrderByDescending(g => g).Skip(3);
Console.WriteLine("All grades except the top three are:");
foreach (int grade in lowerGrades)
{
Console.WriteLine(grade);
}
/*
