Generates a sequence of integral numbers within a specified range.
System.Core (in System.Core.dll)
Public Shared Function Range (
start As Integer,
count As Integer
) As IEnumerable(Of Integer)
The value of the first integer in the sequence.
The number of sequential integers to generate.
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.
The following code example demonstrates how to use Range to generate a sequence of values.
' Generate a sequence of integers from 1 to 10
' and project their squares.
Dim squares As IEnumerable(Of Integer) = _
Enumerable.Range(1, 10).Select(Function(x) x * x)
Dim output As New System.Text.StringBuilder
For Each num As Integer In squares
' Display the output.
' This code produces the following output:
