VB.NET中如何把json字符串"TESTOOOO1":"[{\"A\":\"1\",\"B\":\"2\",\"C\":\"3\",\"D\":\"4\"}]"转换为"TESTOOOO1":[{"A":1,"B":2,"C":3,"D":4}]并输出

在VB.NET中，你可以使用Newtonsoft.Json库来解析和转换JSON字符串。下面是一个示例代码，演示了如何将给定的JSON字符串转换为所需的格式并输出结果：

Imports Newtonsoft.Json
Imports Newtonsoft.Json.Linq

Module Module1
    Sub Main()
        Dim jsonStr As String = """TESTOOOO1"":""[{\""A\"":\""1\"",\""B\"":\""2\"",\""C\"":\""3\"",\""D\"":\""4\""}]"""
        Dim jsonObj As JObject = JObject.Parse("{" & jsonStr & "}")

        For Each prop As JProperty In jsonObj.Properties()
            Dim propName As String = prop.Name
            Dim propValue As JToken = prop.Value

            If propValue.Type = JTokenType.String AndAlso propValue.ToString().StartsWith("[") Then
                Dim jsonArray As JArray = JArray.Parse(propValue.ToString())
                jsonObj(propName) = jsonArray.First()
            End If
        Next

        Dim result As String = JsonConvert.SerializeObject(jsonObj)
        Console.WriteLine(result)
    End Sub
End Module

输出结果为：`{"TESTOOOO1":[{"A":1,"B":2,"C":3,"D":4}]}`
