Question

我正在尝试将列表转换为json字符串。 json生成正常，但是当我尝试在JSON中生成一个数组时，它不会正确格式化。

我的列表已生成

List<string> invoicesList = new List<string>();

        foreach (var invoice in theInvoices)
        {
            invoicesList.Add(invoice.InvoiceNumber);
            invoicesList.Add(String.Format("{0:c}", invoice.GrandTotal));
            invoicesList.Add(FieldTranslation.ToShortDate(invoice.Date.ToString()));
        }

然后我将它添加到JSON

var info = new MobileAPIHelper.ClientPayrollInfo
        {
            GrossWages = String.Format("{0:c}", GrossWages),
            InvoiceTotal = String.Format("{0:c}", invoiceTotal),
            InvoiceDate = FieldTranslation.ToShortDate(invoiceDate.ToString()),
            InvoiceList = invoicesList.ToArray()

        };

输出最终只是一个长JSON字符串，包含列表中的所有内容

"InvoiceList":["SALES000000000006","$9,300.00","4/11/2016","SALES000000000008","$4,650.00","12/22/2015"]

我无法弄清楚如何让list / json格式化那样的invoicelist：

"InvoiceList":[{
"SALES000000000006","$9,300.00","4/11/2016"
},{
"SALES000000000008","$4,650.00","12/22/2015"
}]

Answer 1

invoicesList不是包含这些值的对象列表，而是一个字符串列表。您需要创建一个充当

容器的类

invoice.InvoiceNumber;
String.Format("{0:c}", invoice.GrandTotal);
invoice.Date.ToString());

这些领域。使invoices列出该类的列表，然后将其解析为json。你正在添加原始字符串。

Answer 2

如果您将这些字符串作为对象。

import threading
import paramiko
import subprocess

def ssh_command(ip,user,passwd,command):
    client = paramiko.SSHClient()
    client.set_missing_host_key_policy(paramiko.AutoAddPolicy())
    client.connect(ip,username = user, password = passwd)
    ssh_session = client.get_transport().open_session()
    if ssh_session.active:
        ssh_session.exec_command(command)
        print ssh_session.recv(1024)
    return

ssh_command('192.168.100.301','GLZ','TripleBody','id')

然后有一个名为NewtonSoftJson的包，允许您从Collection转换。

转到包管理器控制台（单击visual studio中的视图菜单 - ＆gt;其他窗口 - ＆gt;包管理器控制台）

Install-Package Newtonsoft.Json

C＃代码

var invoiceListString = JsonConvert.SerializeObject（invoicesList）;

Answer 3

我建议使用NewtonSoft.Json。

class PostModel(admin.ModelAdmin):
    list_display = ('id', 'title', 'pub_date', 'course',)
    search_fields = ('title', 'course__alias',)

    form = PostModelForm

输出1

public class Invoice { public string InvoiceNumber { get; set; } public DateTime InvoiceDate { get; set; } public string InvoiceTotal { get; set; } } public void PrintJson() { List<Invoice> InvoiceList = new List<Invoice>(); var outputObject = new { InvoiceList }; InvoiceList.Add(new Invoice { InvoiceNumber = "SALES0000001", InvoiceDate = DateTime.UtcNow, InvoiceTotal = String.Format("{0:c}", "90000") }); InvoiceList.Add(new Invoice { InvoiceNumber = "SALES0000002", InvoiceDate = DateTime.UtcNow, InvoiceTotal = String.Format("{0:c}", "60000") }); var output1 = JsonConvert.SerializeObject(outputObject); var output2 = JsonConvert.SerializeObject(InvoiceList); }

输出2

{"InvoiceList":[{"InvoiceNumber":"SALES0000001","InvoiceDate":"2017-02-22T16:46:31.6933956Z","InvoiceTotal":"90000"},{"InvoiceNumber":"SALES0000002","InvoiceDate":"2017-02-22T16:46:31.6933956Z","InvoiceTotal":"60000"}]}

请注意您问题中的Json无效。

Answer 4

正如Dispersia指出的那样，你的列表是一个大字符串列表，因此，json序列化程序的行为与请求一致 - 将这个大字符串列表转换为一个大的json字符串数组。

我手边的VS还没有测试下面的代码，但是请尝试将发票清单改为：

List<Tuple<String, String, String>> invoiceList = new List<>();

然后相应地添加元组：

foreach (var invoice in theInvoices)
{
  Tuple<String, String, String> t = new Tuple<>(
      invoice.InvoiceNumber,
      String.Format("{0:c}", invoice.GrandTotal),
      FieldTranslation.ToShortDate(invoice.Date.ToString()));
  invoicesList.Add(t);
}

那会有帮助吗？
