Ejemplos

En el ejemplo de código siguiente se muestra cómo usar Skip<TSource>(IQueryable<TSource>, Int32) para omitir un número especificado de elementos de una matriz ordenada y devolver los elementos restantes.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

El Skip<TSource>(IQueryable<TSource>, Int32) método genera un MethodCallExpression que representa la llamada a Skip<TSource>(IQueryable<TSource>, Int32) sí mismo como un método genérico construido.The Skip<TSource>(IQueryable<TSource>, Int32) method generates a MethodCallExpression that represents calling Skip<TSource>(IQueryable<TSource>, Int32) itself as a constructed generic method. A continuación, pasa el MethodCallExpression al CreateQuery(Expression) método de IQueryProvider representado por la Provider propiedad del source parámetro.It then passes the MethodCallExpression to the CreateQuery(Expression) method of the IQueryProvider represented by the Provider property of the source parameter.

El comportamiento de la consulta que se produce como resultado de ejecutar un árbol de expresión que representa Skip<TSource>(IQueryable<TSource>, Int32) la llamada depende de la implementación del tipo del source parámetro.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. El comportamiento esperado es que omite los primeros count elementos de source y devuelve los elementos restantes.The expected behavior is that it skips the first count elements in source and returns the remaining elements.
