Search for Object in Generic List

Question

Is it possible to search for an object by one of its properties in a Generic List?

Public Class Customer

    Private _id As Integer

    Private _name As St         


        

Answer 1

Generally you need to use predicates:

list.Add(New Customer(1, "A"))
list.Add(New Customer(2, "B"))

Private Function HasID1(ByVal c As Customer) As Boolean
    Return (c.ID = 1)
End Function

Dim customerWithID1 As Customer = list.Find(AddressOf HasID1)

Or with inline methods:

Dim customerWithID1 As Customer = list.Find(Function(p) p.ID = 1)
