C#JSON字符串反序列化

Question

我真的很难在C#中找到JSON反序列化的任何示例,其中每个JSON项中的第一个属性是不同的ID.

    {
       "12112083":{
           "Topic_ID":"12112083",
           "Moved_ID":"51",
           "subject":"subject text goes here"      
           },
       "12111966":{
           "Topic_ID":"12111966",
           "Moved_ID":"51",
           "subject":"another subject text"      
           },
       "12106917":{
           "Topic_ID":"12106917",
           "Moved_ID":"0",
           "subject":"test"      
           }
    }

我尝试了几种不同的方法但没有成功.我无法控制的JSON返回有时是单个项目,有时是一组项目,如上例所示.理想情况下,如果可能,我想反序列化为类型化的对象类.

谢谢

我尝试通过以下字符串提供的代码示例

我收到了"InvalidCastException",无法将"System.String"类型的对象强制转换为"Newtonsoft.Json.Linq.JObject".

我尝试从字符串的开头和结尾删除单引号但得到相同的消息？

使用Json.Net

(发布的JSON无效.在\u005C"使用\u005C.替换无效的s 后,以下工作.)

string json = @"{""12112083"":{""Topic_ID"":""12112083"",""Moved_ID"":""51"",""subject"":""Due to a computer virus, many of my files are \u005CCrypted\u005C,espe"",""Start_date"":""10/6/2012 6:54:37 PM"",""InitialResponseDueDate"":""10/6/2012 7:01:37 PM"",""Locked"":""0"",""QValue"":""$10"",""Status"":""1"",""Author_ID"":""71318191"",""Question_Text"":""Due to a computer virus, many of my files are \u005CCrypted\u005C,especially my pictures.
