次のコード例は、使用する方法を示しますSkip<TSource>(IQueryable<TSource>, Int32)を要素の並べ替え済み配列の指定した数をスキップし、残りの要素を返します。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

注釈

Skip<TSource>(IQueryable<TSource>, Int32)メソッドを生成、MethodCallExpression呼び出しを表すSkip<TSource>(IQueryable<TSource>, Int32)として構築されたジェネリック メソッド自体。The Skip<TSource>(IQueryable<TSource>, Int32) method generates a MethodCallExpression that represents calling Skip<TSource>(IQueryable<TSource>, Int32) itself as a constructed generic method. これは、後、渡します、MethodCallExpressionCreateQuery(Expression)のメソッド、IQueryProviderによって表される、Providerのプロパティ、sourceパラメーター。It then passes the MethodCallExpression to the CreateQuery(Expression) method of the IQueryProvider represented by the Provider property of the source parameter.

呼び出し元を表す式ツリーを実行した結果として発生するクエリの動作Skip<TSource>(IQueryable<TSource>, Int32)の型の実装によって異なります、sourceパラメーター。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. 想定される動作は、最初にスキップするcount要素source残りの要素を返します。The expected behavior is that it skips the first count elements in source and returns the remaining elements.
