如何使用Newtonsoft Json.net在這個反序列化的對象中循環/迭代？

Question

我有以下JSON對象：-

    Public Class oPartner
        Public Property PartnerID() As String
        Public Property PartnerTitle() As String
        Public Property PartnerStrapline() As String
        Public Property PartnerData() As String
    End Class

以及以下partners.json JSON文件：-

[
  {
    "PartnerID": "1",
    "PartnerTitle": "TITLE1",
    "PartnerStrapline": "STRAP1",
    "PartnerData": "SOME INFO IN HERE",
    "PartnerImage": ""
  },
  {
    "PartnerID": "2",
    "PartnerTitle": "TITLE2",
    "PartnerStrapline": "STRAP2",
    "PartnerData": "SOME MORE INFO IN HERE",
    "PartnerImage": ""
  },
  {
    "PartnerID": "3",
    "PartnerTitle": "TITLE3",
    "PartnerStrapline": "STRAP3",
    "PartnerData": "MORE INFO",
    "PartnerImage": ""
  }
] 

所以我可以使用以下方法讀取JSON並反序列化：

Dim data As oPartner = JsonConvert.DeserializeObject(Of oPartner)(File.ReadAllText("c:\partners.json"))

但是我不知道如何在vb（或C＃）中遍歷json？

Answer 1

JSON表示對象數組，但是您嘗試將其反序列化為單個實例。 您需要反序列化為oPartner的數組（或List）。 像這樣嘗試：

Dim data As List(Of oPartner) = JsonConvert.DeserializeObject(Of List(Of oPartner))(File.ReadAllText("c:\partners.json"))

然后，您可以像這樣遍歷列表：

For Each partner As oPartner In data
    Console.WriteLine(partner.PartnerID)
    Console.WriteLine(partner.PartnerTitle)
    Console.WriteLine(partner.PartnerStrapline)
    Console.WriteLine(partner.PartnerData)
    Console.WriteLine()
Next
