In C# I have been performing a FindAll in a generic list as follows:

List<group.category> tlist = list.FindAll(p => p.parid == titem.catid);

Two questions, is this the appropriate way of performing such a thing and how do I convert this to VB.Net

Dim tlist As List(Of group.category) _
    = list.FindAll(Function(p) p.parid = titem.catid)
