我怎樣才能從這個字符串中使用newtonsoft以.json或任何其他方式的值（單獨的對象和值）。

我想是這樣的（通過創建根對象，只是一個小試）

public class RootobjectOne 
     { 
      [JsonProperty("topdealMaster")] 
      public TopdealMaster TopdealMaster { get; set; } 
     } 

     public class TopdealMaster 
     { 
      [JsonProperty("topdeal_id")] 
      public string topdealId {get;set;} 

     }

，然後卡萊它這樣

string b = client.GetPromotionalTopDeal_TOUR("TCTZ00021"); // this gives the json string

以及與此嘗試，打電話給上面的類。

RootobjectOne one = JsonConvert.DeserializeObject<RootobjectOne>(b);

但是沒有得到任何成功的結果。請您對此有所幫助。

注意：由於該類型需要JSON對象（例如{「name」：「value」}）才能正確反序列化，所以會出現以下錯誤----->。要修復此錯誤，請將JSON更改爲JSON對象（例如{「name」：「value」}）或將反序列化類型更改爲實現集合接口（例如ICollection，IList）的數組或類型，如List可以從JSON數組中反序列化。 JsonArrayAttribute也可以添加到類型中，以強制它從JSON數組反序列化。

你有頂級的數組，所以它應該是：

var items = JsonConvert.DeserializeObject<List<RootobjectOne>>(b);

而且"topdealMaster"是一個數組，所以根類應該是這樣的：

public class RootobjectOne 
{ 
    [JsonProperty("topdealMaster")] 
    public Topdealmaster[] TopdealMasters { get; set; } 
}
