Bypasses a specified number of elements in a sequence and then returns the remaining elements.
public:
generic <typename TSource>
[System::Runtime::CompilerServices::Extension]
static System::Linq::IQueryable<TSource> ^ Skip(System::Linq::IQueryable<TSource> ^ source, int count);
public static System.Linq.IQueryable<TSource> Skip<TSource> (this System.Linq.IQueryable<TSource> source, int count);
static member Skip : System.Linq.IQueryable<'Source> * int -> System.Linq.IQueryable<'Source>
<Extension()>
Public Function Skip(Of TSource) (source As IQueryable(Of TSource), count As Integer) As IQueryable(Of TSource)
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
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.
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
*/
Dim grades() As Integer = {59, 82, 70, 56, 92, 98, 85}
' Sort the grades in descending order and
' get all except the first three.
Dim lowerGrades = grades.AsQueryable() _
.OrderByDescending(Function(g) g) _
.Skip(3)
Dim output As New System.Text.StringBuilder
output.AppendLine("All grades except the top three are:")
For Each grade As Integer In lowerGrades
output.AppendLine(grade)
Next
' Display the output.
MsgBox(output.ToString())
' 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.
