Try this.
otrocarros = (From c In crs Where c.Color.StartsWith("R") Select c).ToList

It did not work..... got this error:
Unable to cast object of type 
'System.Collections.Generic.List`1[UseWebParts.Car]' to type 'UseWebParts.Cars'.

Hi, can someone tell me what is wrong with this?

I am having this error:
Unable to cast object of type 
'WhereSelectListIterator`2[Sample.Car,Sample.Car]' to type 'Sample.Cars'.


This is my code, the error occurs in the Red Line:

Partial Public Class _Default
    Inherits System.Web.UI.Page

    Protected Sub Page_Load(ByVal sender As Object, ByVal e As 
System.EventArgs) Handles Me.Load

        Dim crs As New Cars
        crs.Add(New Car() With {.Color = "Rojo"})
        crs.Add(New Car() With {.Color = "Verde"})
        crs.Add(New Car() With {.Color = "Rojo"})
        crs.Add(New Car() With {.Color = "Azul"})

        Dim otrocarros As Cars
        otrocarros = From c In crs Where c.Color.StartsWith("R") Select c
        For Each oc In otrocarros
            Response.Write(oc.Color.ToString)
        Next

    End Sub

End Class

Public Class Cars
    Inherits List(Of Car)

End Class

Public Class Car

    Private _color As String
    Public Property Color() As String
        Get
            Return _color
        End Get
        Set(ByVal value As String)
            _color = value
        End Set
    End Property

End Class


Thanks!!!
