如何在C＃中将多个对象作为单个json传递？ [英] How to pass multiple object as single json in C#?

问题描述

如何将多个对象作为单个json格式传递
我的对象如下所示
 
 public class Emp 
 {
 public string Id {得到;组; } 
 public string Name {get;组; } 
} 
 
现在我需要传递json，如下所示
 
 [
 {
Id：John，
姓名：美国
}，
 {
Id：John，
姓名：US
}，
 {
Id：John，
姓名：US
}，
 {
Id：John， 
姓名：美国
} 
] 

我有什么尝试过：



我尝试使用下面的代码，但获取单个json对象的正确数据。

但我需要在方括号内获取多个数据。

您能否建议如何使用逗号分隔来获取多个对象。

使用Newtonsoft.Json; 
使用System; 
使用System.Collections.Generic; 
 namespace ToCommaExample 
 {
 class program 
 {
 static void Main（string [] args）
 {
 Service objService = new Service（ ）; 
服务objService2 = new Service（）; 
 var listData = new List< SecurityAuditData> 
 {
 new SecurityAuditData {TransactionName =UserAdded，
 EntityID =[e-mail]，
 UserIdentity =identity1}，
 
}; 
 var listData2 = new List< SecurityAuditData> 
 {
 new SecurityAuditData {TransactionName =SecurityRoleUpdated，
 EntityID =[e-mail]，
 UserIdentity =identity2}，
 
}; 
 objService.AuditData = listData; 
 objService2.AuditData = listData2; 
 var finalJson = JsonConvert.SerializeObject（objService2.AuditData，Formatting.Indented）; 
 Console.WriteLine（finalJson）; 
 Console.Read（）; 
} 
} 
 
 
公共类SecurityAuditData 
 {
 public string TransactionName {get;组; } 
公共字符串EntityID {get;组; } 
公共字符串UserIdentity {get;组; } 
 
} 
类服务
 {
 [NonSerialized] 
 
公共对象AuditData; 
} 
 
} 

现在输出如下

 [
 {
TransactionName：SecurityRoleUpdated，
EntityID：[e-mail]，
UserIdentity：identity2
} 
] 

预期输出

 [
 {
TransactionName：SecurityRoleUpdated ，
EntityID：[e-mail]，
UserIdentity：identity2
}，
 {
TransactionName：UserAdded ，
EntityID：[e-mail]，
UserIdentity：identity1
} 
] 

解决方案

是的非常简单你可以把这个列表传递给JSON序列化



使用Newtonsoft.Json;



var json = JsonConvert.SerializeObject（yourlist_here）;



为此你必须通过NuGet将它安装到你的项目中包管理器（工具 - > NuGet包管理器 - >包管理器控制台）：



PM>安装包Newtonsoft.Json

做类似的事情



var finalJson = json.Serialize（classObj）;

How to pass multiple object as single json format
my object like below

public class Emp
{
    public string Id{ get; set; }
    public string Name{ get; set; }
}

Now i need to pass json like below

[  
    {
        "Id": "John",
        "Name": "US"
    },
    {
        "Id": "John",
        "Name": "US"
    },
    {
        "Id": "John",
        "Name": "US"
    },
    {
        "Id": "John",
        "Name": "US"
    }
]

What I have tried:

I have tried with the below code but getting proper data for single json object.
But i need to get multiple data within square brackets.
Could you please suggest how to proceed to get multiple object with comma separated.

using Newtonsoft.Json;
using System;
using System.Collections.Generic;
namespace ToCommaExample
{
    class Program
    {
        static void Main(string[] args)
        {
            Service objService = new Service();
            Service objService2 = new Service();
            var listData = new List<SecurityAuditData>
            {
                new SecurityAuditData {TransactionName = "UserAdded",
                EntityID = "[e-mail]",
                UserIdentity = "identity1"},
                
            };
            var listData2 = new List<SecurityAuditData>
            {
                new SecurityAuditData {TransactionName = "SecurityRoleUpdated",
                EntityID = "[e-mail]",
                UserIdentity = "identity2"},

            };
            objService.AuditData = listData;
            objService2.AuditData = listData2;
            var finalJson = JsonConvert.SerializeObject(objService2.AuditData, Formatting.Indented);
                      Console.WriteLine(finalJson);
            Console.Read();
        }
    }

  
    public class SecurityAuditData
    {
        public string TransactionName { get; set; }
        public string EntityID { get; set; }
        public string UserIdentity { get; set; }
       
    }
    class Service
    {
        [NonSerialized]
  
        public object AuditData;
    }

}

Present output like below

[
  {
    "TransactionName": "SecurityRoleUpdated",
    "EntityID": "[e-mail]",
    "UserIdentity": "identity2"
  }
]

Expected output

[
  {
    "TransactionName": "SecurityRoleUpdated",
    "EntityID": "[e-mail]",
    "UserIdentity": "identity2"
  },
 {
    "TransactionName": "UserAdded",
    "EntityID": "[e-mail]",
    "UserIdentity": "identity1"
}
]

解决方案

yes its very simple you can pass this list to JSON Serialize

using Newtonsoft.Json;

var json = JsonConvert.SerializeObject(yourlist_here);

for this you have to install this into your project via the NuGet Package Manager (Tools --> NuGet Package Manager --> Package Manager Console):

PM> Install-Package Newtonsoft.Json

Do something like this

var finalJson = json.Serialize(classObj);
