我在 JSON 反序列化方面遇到了问题，希望您能帮助我。我有一个包含以下信息的 JSON：
{
"object":"list",
"more":false,
"data":[
{
"object":"number",
"id":"1",
"code":"1",
"name":"One",
},
{
"object":"number",
"id":"2",
"code":"2",
"name":"Two",
}
...
所以我创建了一个简单的应用程序，以便我可以使用该信息：
Private Sub Button1_Click(sender As Object, e As EventArgs) Handles Button1.Click
Dim uriString As String = "API URL"
Dim uri As New Uri(uriString)
'Make Request
Dim Request As HttpWebRequest = HttpWebRequest.Create(uri)
Request.Method = "GET"
'Get Response
Dim Response As HttpWebResponse = Request.GetResponse()
'Read Response
Dim Read = New StreamReader(Response.GetResponseStream())
Dim Raw As String = Read.ReadToEnd()
'Convert response
Dim dict As Object = New JavaScriptSerializer().Deserialize(Of List(Of Object))(Raw)
For Each item In dict
MsgBox(item)
MsgBox(item("code"))
TextBox1.Text += item("code").ToString + " - " + item("name").ToString + vbNewLine
Next
End Sub
似乎我得到了响应，因为 Read 我得到了 JSON，但在那之后，我无法得到该 JSON 中列出的信息。我做错了什么？
您没有正确反序列化。你的字典是空的。
这将按预期工作。
Private Sub Button1_Click(sender As Object, e As EventArgs) Handles Button1.Click
Dim uriString As String = "API URL"
Dim Request As HttpWebRequest = WebRequest.Create(New Uri(uriString))
Dim JSON_Response As String = New StreamReader(Request.GetResponse().GetResponseStream()).ReadToEnd()
Dim JSON_Obj1 As Object = New JavaScriptSerializer().DeserializeObject(JSON_Response)
Dim Test1 as String = JSON_Obj1("data")(0)("code")
For Each item In JSON_Obj1("data")
Debug.Print(item("code"))
Next
End Sub
