扫描结果包含扫描详细信息时出现问题，该扫描详细信息将反病毒名称与某些详细信息相冲突。但所有的反病毒都是对象而不是数组。所以请任何人告诉我怎么做

首先，需要创建一个类或多个类来表示要反序列化的数据

查看您提供的输入字符串，您需要一个FileInfo、ScanDetail、ScanResults类和一个根类，我们称之为Scan

这只是将JSON键映射到一个类属性和ScandDetail的字典的问题，因为您可能不希望每个属性都有一个属性

因此，您的类应该如下所示：

public class Scan
    public property file_id() as string
    public property scan_results() AS ScanResults 
    public property file_info() as FileInfo
    public property data_id() as string
End Class

public class ScanResults
    public property scan_details As Dictionary(Of string, ScanDetail)
    Public Property rescan_available() As Boolean
    Public Property data_id() As String
    Public Property scan_all_result_i() As Integer
    Public Property start_time() As String
    Public Property total_time() As Double
    Public Property total_avs() As Integer
    Public Property progress_percentage() As Integer
    Public Property in_queue() As Integer
    Public Property scan_all_result_a() As String
End Class

public class ScanDetail
    public property scan_result_i() As integer
    public property threat_found() as string
    public property def_time() as string
    public property scan_time() as string
End class

Public Class FileInfo
    Public Property file_size() As Integer
    Public Property upload_timestamp() As String
    Public Property md5() As String
    Public Property sha1() As String
    Public Property sha256() As String
    Public Property file_type_category() As String
    Public Property file_type_description() As String
    Public Property file_type_extension() As String
    Public Property display_name() As String
End Class
现在反序列化就像

Dim details = NewtonSoft.JSon.JsonConvert.DeserializeObject(Of Scan)(your_json_string)
要获取所有找到的值，您可以轻松查询结果：

Dim threats = details.scan_results.scan_details.Select(Function(kvp) kvp.Value.threat_found) _
                                               .Where(Function(t) Not String.IsNullOrWhiteSpace(t)) _
                                               .ToList()
假设您已经引用了JSON.Net，下面是如何反序列化JSON字符串。您得到的是一个动态对象，其属性名称与JSON属性名称相同。如果要创建具有正确属性的类，还可以将其反序列化为该特定类型，这样就有了强类型的好处。在这段代码后面放一个断点，然后用Debug运行。在“本地人”窗口中可以查看theobj的房产

    Dim obj As String =

谢谢你们的回复。我已经通过下面的代码片段完成了

 Dim jsonstring = IO.File.ReadAllText("C:\\Users\\Administrator\\Desktop\\json.txt")
    Dim jo = Newtonsoft.Json.Linq.JObject.Parse(jsonstring)
    Dim scanDetail = jo("scan_results")("scan_details")
    Dim virusCount As Integer
    virusCount = 0
    For Each entry As Newtonsoft.Json.Linq.JProperty In scanDetail
        entry.CreateReader()
        Console.WriteLine(entry.Name)
        For Each Val As Object In entry
            Dim abc = Newtonsoft.Json.Linq.JObject.Parse(Val.ToString())
            Dim threatFound As String = abc("threat_found")

            Dim result As Integer = String.Compare(threatFound, "")
            If result = -1 Then
                virusCount = virusCount + 1
            End If



        Next
    Next

    If virusCount = 0 Then
        Console.WriteLine("No Virus")
    Else
        Console.WriteLine("Virus")
    End If
你用来反序列化json字符串的类和你用来实际反序列化的代码是什么样子的？Sloth，我没有做任何事情。事实上，昨天我已经开始在vb.net上工作了。需要一个方法吗？我需要迭代json。实际上，我需要得到特定文件的病毒计数。所以从你的代码我想我做不到不，你可以。你可以得到任何值，但使用@sloth的方法会更容易。或者，您可以安装Visual Studio的Web Essentials，它会将“粘贴json作为类”项添加到“编辑”菜单中。。。虽然我不确定它是VB.Net还是c。你能看到我的答案吗，我已经做了。。。但只需要验证是否有其他性能更好的方法，我需要获得特定文件上的病毒计数。所以从你的代码我想我做不到it@user1679960您的JSON字符串中没有病毒计数。@user1679960您似乎在寻找找到的威胁。我更新了我的答案。事实上，你不需要在VB中逃避路径中的反斜杠，所以它应该是C:\Users\Administrator\Desktop\json.txt。你真的不应该以管理员的身份登录，但那是另一个论坛。谢谢安德鲁·莫伦，我真的不知道。如果你认为它是正确的，请标记它为正确答案，因为我无法这样做。48小时后你应该能够接受你自己的答案。
