JScript does not support generic types or methods.

Usage Note

The Take<(Of <(TSource>)>)(IQueryable<(Of <(TSource>)>), Int32) method generates a MethodCallExpression that represents calling Take<(Of <(TSource>)>)(IQueryable<(Of <(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 Take<(Of <(TSource>)>)(IQueryable<(Of <(TSource>)>), Int32) depends on the implementation of the type of the source parameter. The expected behavior is that it takes the first count elements from the start of source.

The following code example demonstrates how to use Take<(Of <(TSource>)>)(IQueryable<(Of <(TSource>)>), Int32) to return elements from the start of a sequence.

Dim grades() As Integer = {59, 82, 70, 56, 92, 98, 85}

' Sort the grades in descending order and take the first three.
Dim topThreeGrades = _
    grades.AsQueryable().OrderByDescending(Function(grade) grade).Take(3)

Dim output As New System.Text.StringBuilder
output.AppendLine("The top three grades are:")
For Each grade As Integer In topThreeGrades
    output.AppendLine(grade)
Next

' Display the output.
MsgBox(output.ToString())

' This code produces the following output:

' The top three grades are:
' 98
' 92
' 85

int[] grades = { 59, 82, 70, 56, 92, 98, 85 };

// Sort the grades in descending order and take the first three.
IEnumerable<int> topThreeGrades =
    grades.AsQueryable().OrderByDescending(grade => grade).Take(3);

Console.WriteLine("The top three grades are:");
foreach (int grade in topThreeGrades)
    Console.WriteLine(grade);

/*
    This code produces the following output:

    The top three grades are:
    98
    92
    85
*/
