如何搜索T是自定义数据类的List(of T)？

Question

我认为我的问题比标题更复杂.假设我有联系人的数据类:

Public Class Contact
    Public Property Name As String
    Public Property Phone As String
    Public Property Fax As String
    Public Property Email As String
End Class

我有一个List(Of Contact)有几个不同联系人的对象.我如何搜索List其中一个属性的内容并返回结果Contact对象？

Answer 1

Linq可能是最简单的方法.匹配变量是另一个列表(联系人)

    Dim list As List(Of Contact) = {New Contact With {.Name = "Andy", .Phone = "1234", .Fax = "", .Email = ""}}

    Dim matches = From c In list
                  Where c.Phone = "1234"
                  Select c

这是一个很好的备忘单,我经常在试图记住这样的事情的基本语法时参考.
