C# 将来自SkyDrive的JSON响应反序列化到自定义类

我想将来自LiveConnectClient.GetAsyncme/skydrive/files的JSON响应反序列化到自定义类，以确定skydrive根目录上是否存在特定文件夹。我从skydrive获得json结果，并使用json2csharp.com获得类结构。然后，我使用Json.net的DeserializeObject方法将Json反序列化为类结构。但它在执行期间抛出异常。我没有转换json结果就得到了想要的结果。但我想知道哪里出了问题，以及如何将其转换为自定义类。代码如下所示

private async void btnFldrStruct_Click(object sender, RoutedEventArgs e)
    {
        LiveOperationResult opResult = await client.GetAsync("me/skydrive/files");
        dynamic skyResult = opResult.Result;
        var fileList = skyResult.data;
        SkyDrive skydrive = JsonConvert.DeserializeObject<SkyDrive>(fileList);
        ...
    }

信息 与“Newtonsoft.Json.JsonConvert.DeserializeObjectstring”匹配的最佳重载方法

有人能告诉我这里出了什么问题以及如何解决吗。谢谢

filelist是否为string类型？消息“Newtonsoft.Json.JsonConvert.DeserializeObjectstring”的最佳重载方法匹配具有一些无效参数必须表示“filelist”不是预期的类型。。。文件列表不是一个字符串。我使用var是因为我不知道结果的类型。我明白了，因为fileList不是字符串JsonConvert.DeserializeObjectfileList；抛出异常。那么我如何获取json字符串呢？skyResult是一种动态类型。如何从中提取json字符串？您是否尝试过ToString？请尝试从调试器中检查文件列表的属性。@ChrisK-在skyResult.data上使用ToString会导致此异常Newtonsoft.Json.JsonReaderException消息：在分析值时遇到意外字符：S。路径，第0行，位置0。
