如何解析這個JSON

Question

這就是我的Json

} 

這是我的類定義

    public string count { get; set; } 
    [JsonProperty("threads")] 
    public Threads threads { get; set; } 

}

} 

，但我得到的錯誤

無法反序列化當前的JSON對象（例如{ 「name」：「value」}）轉換爲類型'System.Collections.Generic.List`1 [AppHandHeld.Class.Threads]'，因爲類型需要一個JSON數組（例如[1,2,3]）來正確地反序列化。 要修復此錯誤，請將JSON更改爲JSON數組（例如[1,2,3]）或更改反序列化的類型，以使其爲正常的.NET類型（例如，不是像整數這樣的基本類型，也不是集合類型像數組或列表），可以從JSON對象反序列化。 JsonObjectAttribute也可以添加到類型中，以強制它從JSON對象反序列化。 路徑 '計數'，1號線，9號位置

Answer 1

這是一個難題：

[JsonProperty("threads")] 
public Threads threads { get; set; } 

哪個解析器的樣子：

{ 
    "threads": { <single thread object> } 
} 

它需要是：

[JsonProperty("threads")] 
public Threads[] threads { get; set; } 

看起來像這樣：

{ 
    "threads": [<array of thread objects>] 
} 

它是如何在您提供的JSON示例中。然後，你還可以：

[JsonProperty("custom_fields")] 
public string custom_fields { get; set; } 

這將意味着在JSON：

{ 
    "custom_fields": "<some string>" 
} 

然而在JSON它實際上是：

{ 
    "custom_fields": [<an array>] 
} 

這應該是這樣的：

[JsonProperty("custom_fields")] 
public string[] custom_fields { get; set; } 

而且你還有Thread_Result：

[JsonProperty("count")] 
public string Count { get; set; } 

這應該是：

[JsonProperty("count")] 
public int Count { get; set; } 

其實你這樣做的幾乎所有數值，嘗試並使用正確的值類型和讓JSON解析器做爲你解析。

開始解決這些基本問題，並看看你如何繼續。
