Json.net嘗試反序列化，從異常

Question

繼承的類我有一個類SearchError從Exception繼承和失敗時當過我嘗試從一個有效的JSON我得到下面的異常反序列化：

ISerializable type 'SearchError' does not have a valid constructor. To correctly implement ISerializable a constructor that takes SerializationInfo and StreamingContext parameters should be present. Path '', line 1, position 81. 

我試圖實現建議缺少的構造函數，並沒有幫助。

這是落實建議的構造後級：

public class APIError : Exception 
{ 
    [JsonProperty("error")] 
    public string Error { get; set; } 

    [JsonProperty("@http_status_code")] 
    public int HttpStatusCode { get; set; } 

    [JsonProperty("warnings")] 
    public List<string> Warnings { get; set; } 

    public APIError(string error, int httpStatusCode, List<string> warnings) : base(error) 
    { 
     this.Error = error; 
     this.HttpStatusCode = httpStatusCode; 
     this.Warnings = warnings; 
    } 

    public APIError(System.Runtime.Serialization.SerializationInfo info, System.Runtime.Serialization.StreamingContext context) 
     : base(info, context) 
    { 
     Error = (string)info.GetValue("error", typeof(string)); 
     HttpStatusCode = (int)info.GetValue("@http_status_code", typeof(int)); 
     Warnings = (List<string>)info.GetValue("warnings", typeof(List<string>)); 
    } 
} 

現在我收到以下異常（也json.net代碼）：

Member 'ClassName' was not found. 

我也試過實施與this related question相同的解決方案，也得到了上述相同的錯誤。

這個問題已經在這裏找到答案：https://stackoverflow.com/a/3423037/504836

添加一個新的構造

public Error(SerializationInfo info, StreamingContext context){} 

解決我的問題。

這裏完整代碼：

[Serializable] 
public class Error : Exception 
{ 

    public string ErrorMessage { get; set; } 

    public Error(SerializationInfo info, StreamingContext context) { 
     if (info != null) 
      this.ErrorMessage = info.GetString("ErrorMessage"); 
    } 
    public override void GetObjectData(SerializationInfo info,StreamingContext context) 
    { 
     base.GetObjectData(info, context); 

     if (info != null) 
      info.AddValue("ErrorMessage", this.ErrorMessage); 
    } 
}

由於錯誤說，你缺少序列化的構造函數：

public class SearchError : Exception 
{ 
    public SearchError(System.Runtime.Serialization.SerializationInfo info, System.Runtime.Serialization.StreamingContext context) : base(info, context) 
    { 

    } 
}
