我刚开始解析程序中的Json结构。 我的ServerResponse如下所示。
我不知道如何在这里粘贴json结构。因此，我只是在这里复制并粘贴结构。

现在这是我的VB.NET代码：
Dim json As String = responseFromServer
Dim ser As JObject = JObject.Parse(json)
Dim data As List(Of JToken) = ser.Children().tolist() 'VisualStudio shows me error here that ToList is not a member of Newtonsoft.Json.Linq.JToken
Dim output As String = ""
所以我无法将孩子们保存在名单中。你能告诉我如何使用vb.net访问“Linked”子项下的json结构中的href元素。
如果您提供一个使用vb.net代码从Json Structure访问以下行的示例，我将非常感谢您。

答案 0 :(得分：1)
ToList方法是IEnumerable(Of T)接口的extension method。它由 System.Core.dll 库在System.Linq命名空间中定义。因此，除非您引用该库并导入该命名空间，否则您将无法在任何可枚举对象上看到ToList方法。 ToList不是由可枚举类型本身定义的方法。它是一个由该库自动附加到类型接口的方法，但仅在引用扩展它的库并导入命名空间时才会附加。
LINQ及其所有扩展方法已添加到.NET Framework的3.5版本中，因此如果您的项目定位到3.0或更早版本，则无法访问任何扩展方法。 / p>
