C＃无法反序列化当前JSON对象例如{“ name”：“ value”}

如何解决C＃无法反序列化当前JSON对象例如{“ name”：“ value”}

我正在尝试反序列化JSON响应，我已经对此进行了大量搜索，并且我知道有很多与此相关的帖子，但没有一个女巫起作用。

在下面，您将看到JSON响应：

{
"id": "xxx","name": "xxx","value": 138000,"type": "sales","tags": "","external_id": "xxx","external_client_id": "api","external_editor_type": "","external_editor_id": "","company_name": "","company_number": "","company_id": "","company_logo_url": "","unique_id": 0,"is_selfsign": true,"is_signing_biometric": true,"is_signing_initials": false,"is_signing_forward": true,"is_identify_recipient": false,"is_private": false,"status": "signed","send_date": "2020-08-14T09:46:04+00:00","sign_date": "2020-08-16T19:51:30+00:00","created_at": "2020-08-14T09:45:21+00:00","user_id": "9n6kgd3p","sender_name": "xxx","sender_thumb_url": "","sender_email": "xxx","email_send_template_id": "xxx","parent_id": "","email_send_subject": "xxx","email_send_message": "xxx","is_signing": true,"is_signing_order": false,"is_signed": true,"expiration_date": "2020-08-28T21:59:00+00:00","is_scheduled_sending": false,"scheduled_sending_time": null,"is_reminder_sending": false,"is_video": false,"video_id": null,"is_auto_comment": false,"auto_comment_text": "","is_auto_comment_email": false,"auto_comment_email": "","entity_auto_comment_text": "","field_count": 0,"contract_start_date": null,"contract_end_date": null,"thumb_url": "xxx","preview_url": "xxx","download_url": "xxx","recipients": [
    {
        "fullname": "xxx","first_name": "xxx","last_name": "xxx","email": "xxx","title": "","note": "","gender": "m","mobile": "","thumb_url": "","role": "signer","order_num": "1"
    }
]

}

我正在使用的类：

public class Recipient
{
    public string fullname { get; set; }
    public string first_name { get; set; }
    public string last_name { get; set; }
    public string email { get; set; }
    public string title { get; set; }
    public string note { get; set; }
    public string gender { get; set; }
    public string mobile { get; set; }
    public string thumb_url { get; set; }
    public string role { get; set; }
    public string company_name { get; set; }
    public string company_number { get; set; }
    public string status { get; set; }
    public string order_num { get; set; }
}

public class Root
{
    public string id { get; set; }
    public string name { get; set; }
    public int value { get; set; }
    public string type { get; set; }
    public string tags { get; set; }
    public string external_id { get; set; }
    public string external_client_id { get; set; }
    public string external_editor_type { get; set; }
    public string external_editor_id { get; set; }
    public string company_name { get; set; }
    public string company_number { get; set; }
    public string company_id { get; set; }
    public string company_logo_url { get; set; }
    public int unique_id { get; set; }
    public bool is_selfsign { get; set; }
    public bool is_signing_biometric { get; set; }
    public bool is_signing_initials { get; set; }
    public bool is_signing_forward { get; set; }
    public bool is_identify_recipient { get; set; }
    public bool is_private { get; set; }
    public string status { get; set; }
    public DateTime send_date { get; set; }
    public DateTime sign_date { get; set; }
    public DateTime created_at { get; set; }
    public string user_id { get; set; }
    public string sender_name { get; set; }
    public string sender_thumb_url { get; set; }
    public string sender_email { get; set; }
    public string email_send_template_id { get; set; }
    public string parent_id { get; set; }
    public string email_send_subject { get; set; }
    public string email_send_message { get; set; }
    public bool is_signing { get; set; }
    public bool is_signing_order { get; set; }
    public bool is_signed { get; set; }
    public DateTime expiration_date { get; set; }
    public bool is_scheduled_sending { get; set; }
    public object scheduled_sending_time { get; set; }
    public bool is_reminder_sending { get; set; }
    public bool is_video { get; set; }
    public object video_id { get; set; }
    public bool is_auto_comment { get; set; }
    public string auto_comment_text { get; set; }
    public bool is_auto_comment_email { get; set; }
    public string auto_comment_email { get; set; }
    public string entity_auto_comment_text { get; set; }
    public int field_count { get; set; }
    public object contract_start_date { get; set; }
    public object contract_end_date { get; set; }
    public string thumb_url { get; set; }
    public string preview_url { get; set; }
    public string download_url { get; set; }
    public List<Recipient> recipients { get; set; }
}

我正在尝试像这样反序列化

var data = JsonConvert.DeserializeObject<List<Root>>(response.Content);
email_send_message = data[0].email_send_subject;
Console.WriteLine(email_send_subject + " " + email_send_message);

我收到此错误：

无法将当前JSON对象（例如{“ name”：“ value”}）反序列化为类型'System.Collections.Generic.List`1 [TelerikWinFormsApp1.GetAcceptAPI + DownloadSignedDocument + Root]'，因为该类型需要JSON数组（例如[1,2,3]）正确反序列化。 要解决此错误，可以将JSON更改为JSON数组（例如[1,3]），也可以更改反序列化类型，使其成为普通的.NET类型（例如，不像整数这样的原始类型，也不像这样的集合类型）数组或列表），可以从JSON对象反序列化。还可以将JsonObjectAttribute添加到类型中，以强制其从JSON对象反序列化。

谁能告诉我我在做什么错，或者至少将我指向正确的方向？

谢谢！

解决方法

更新此

SELECT      a.*,b.*,st_intersection(a.geom,b.geom) as geom
FROM        a,b
WHERE       st_intersects(a.geom,b.geom)

到

from PIL import Image
import numpy as np
from wordcloud import WordCloud
mask = np.array(Image.open('pentagon.jpg'))
wc = WordCloud(mask=mask,scale=5,background_color='white',collocations=False,max_words=500,max_font_size=256)
wc.generate_from_frequencies(k)
wc.prefer_horizontal=0.7
plt.imshow(wc,interpolation="bilinear")
plt.axis('off')
plt.show()

您的Json对象是单个对象，但是您试图反序列化为List，这是错误的
