What can be Short cut Code for following

Short Code for:

    Dim NewItemList As List(Of OrderDetail) = New List(Of OrderDetail)

    For Each Item As OrderDetail In OrderInfoDetails
        If Item.Status = EnumOrderStatus.Taken Then
            NewItemList.Add(Item)
        End If
    Next

Tried:

    Dim NewItemList As List(Of OrderDetail) = From Item As OrderDetail In OrderInfoDetails Where Item.Status = EnumOrderStatus.Taken Select Item

But got a error saying cannot convert where list of orderdetail to generic list

How about simply

Dim NewItemList = OrderInfoDetails.Where(Function(e) e.Status = EnumOrderStatus.Taken).ToList()

For a simple Where I prefer the method syntax. You want a List(Of OrderDetail) instead of a IEnumerable(Of OrderDetail), so you can just call the ToList() extension method.

Use the Where(...) method testing the Status property for equivalency to EnumOrderStatus.Taken via lambda expression, then call the ToList() method

Just wrap your query in a List constructor: 

Dim NewItemList = New List(Of OrderDetail)(From Item As OrderDetail In OrderInfoDetails Where Item.Status = EnumOrderStatus.Taken Select Item)
