如何在C＃中将多个对象作为单个json传递？

本文介绍了如何在C＃中将多个对象作为单个json传递？的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！ 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 =useradded@test， UserIdentity =identity1}， }; var listData2 = new List< SecurityAuditData> { new SecurityAuditData {TransactionName =SecurityRoleUpdated， EntityID =SecurityRoleUpdated@test， 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：SecurityRoleUpdated@test，UserIdentity：identity2} ]

预期输出

[ {TransactionName：SecurityRoleUpdated ，EntityID：SecurityRoleUpdated@test，UserIdentity：identity2}， {TransactionName：UserAdded ，EntityID：useradded@test，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 = "useradded@test", UserIdentity = "identity1"}, }; var listData2 = new List<SecurityAuditData> { new SecurityAuditData {TransactionName = "SecurityRoleUpdated", EntityID = "SecurityRoleUpdated@test", 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": "SecurityRoleUpdated@test", "UserIdentity": "identity2" } ]

Expected output

[ { "TransactionName": "SecurityRoleUpdated", "EntityID": "SecurityRoleUpdated@test", "UserIdentity": "identity2" }, { "TransactionName": "UserAdded", "EntityID": "useradded@test", "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);
