根据 C# 中的项目值将对象数组合并为一个对象

Question

我需要根据项目值将一组对象合并为一个对象 这个想法或多或少是这样的： 我有这个C#方法

private SecurityResponse mergeSecuritySettings(SecurityResponse[] profileDetails)
{
// return merged object
}

其中 SecurityResponse[] 是一组安全配置文件，每个配置文件对于数组中的每一项都有自己的安全设置 例如：

[
  {
    "colorSettings": [
      {
        "settingKey": "A_288",
        "securitySettingValue": "R"
      },
      {
        "settingKey": "A_288_556",
        "securitySettingValue": "R"
      }
    ],
    "speedSettings": [
      {
        "settingKey": "L_19",
        "securitySettingValue": "R"
      },
      {
        "settingKey": "L_19_38",
        "securitySettingValue": "H"
      }
    ],
    "shapeSettings": [
      {
        "settingKey": "P_8",
        "securitySettingValue": "W"
      },
      {
        "settingKey": "P_8_8",
        "securitySettingValue": "W"
      }
    ],
    "brandSettings": [
      {
        "settingKey": "R_340",
        "securitySettingValue": "R"
      },
      {
        "settingKey": "R_337",
        "securitySettingValue": "H"
      }
    ]
  },
  {
  "colorSettings": [
    {
      "settingKey": "A_288",
      "securitySettingValue": "W"
    },
    {
      "settingKey": "A_288_556",
      "securitySettingValue": "W"
    }
  ],
  "speedSettings": [
    {
      "settingKey": "L_19",
      "securitySettingValue": "R"
    },
    {
      "settingKey": "L_19_38",
      "securitySettingValue": "W"
    }
  ],
  "shapeSettings": [
    {
      "settingKey": "P_8",
      "securitySettingValue": "W"
    },
    {
      "settingKey": "P_8_8",
      "securitySettingValue": "W"
    }
  ],
  "brandSettings": [
    {
      "settingKey": "R_340",
      "securitySettingValue": "R"
    },
    {
      "settingKey": "R_337",
      "securitySettingValue": "R"
    }
  ]
}
]

这里的关键是“securitySettingValue”（W = Write，R = Read，H = Hide），输出标准应该从最...到最不宽松（注意每个项目都有一个唯一的settingKey）这将在“SecurityResponse”数组的每个元素上重复），

所以...对于他从上面输入的数据，输出应该是：

{
  "colorSettings": [
    {
      "settingKey": "A_288",
      "securitySettingValue": "W"
    },
    {
      "settingKey": "A_288_556",
      "securitySettingValue": "W"
    }
  ],
  "speedSettings": [
    {
      "settingKey": "L_19",
      "securitySettingValue": "R"
    },
    {
      "settingKey": "L_19_38",
      "securitySettingValue": "W"
    }
  ],
  "shapeSettings": [
    {
      "settingKey": "P_8",
      "securitySettingValue": "W"
    },
    {
      "settingKey": "P_8_8",
      "securitySettingValue": "W"
    }
  ],
  "brandSettings": [
    {
      "settingKey": "R_340",
      "securitySettingValue": "R"
    },
    {
      "settingKey": "R_337",
      "securitySettingValue": "R"
    }
  ]
}

也许解决方案很简单，但如果不进入几个嵌套循环，我就看不到它，（主要是因为我缺乏 C# 知识）。

关于如何处理这个问题有什么建议吗？有内置方法吗？

提前致谢！

尝试这样：

使用

Serialize JSON

和

Deserialize JSON

，查看https://www.newtonsoft.com/json

using System;
using System.Collections.Generic;
using Newtonsoft.Json;

{
    public class BrandSetting

        public string settingKey { get; set; }

    {
        public string settingKey { get; set; }
        public string securitySettingValue { get; set; }
    }
