过滤通用列表（逗号分隔值）

Question

我想过滤列表如下。我有一个类，我想从中过滤值，这些值在我的过滤器字符串中。我已经通过 for 循环实现了我的结果，但需要一种没有 for 循环的方法。

Public Class WorkStationDetails<br><br>
    Property CountryId As Integer<br>
    Property CountryName As String<br>
    Property TotalWrkStn As Integer<br>
    Property ExistingWrkStn As Integer<br>
    Property RemainingWrkStn As Integer<br><br>
End Class

Dim WrkStnDtl As List(Of WorkStationDetails)
Dim FilterWrkStnDtl As List(Of WorkStationDetails)
Dim Numbers As String()

Numbers = "1,5,6,2,9".Split(",")

  For i As Integer = 0 To Numbers.Length - 1
      FilterWrkStnDtl.AddRange(WrkStnDtl.FindAll(Function(p) (p.CountryId = Numbers(i))))
  Next

注意：我想像sql server中的子查询一样实现。

Answer 1

我想你想要这样的东西”

var numbers = "1,5,6,2,9".Split(',');
var selected = WrkStnDtl.Where(w => numbers.Contains(w.CountryId)).ToList();
