该代码实现了一个用于Modbus通信的变量类库，包括变量名称、存储区域、地址等属性，并能从JSON文件中解析数据，用于设备监控和数据管理。此外，还提供了将数据转换为JSON字符串的辅助方法。

建立一个modbus变量类库

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;

namespace JsonPractice
{
    public class Variable_Modbus
    {
        //变量名称
        public string VarName { get; set; }
        //存储区域
        public string StoreArea { get; set; }
        //地址
        public string Address { get; set; }
        //数据类型
        public string DataType { get; set; }
        //是否归档 是否存入数据库
        public string IsFiling { get; set; }
        //是否报警
        public string IsAlarm { get; set; }
        //是否制作报表
        public string IsReport { get; set; }
        //变量注释说明
        public string Note { get; set; }
        //绝对地址
        private string absoluteAddress;
        //判断存储区
        public string AbsoluteAddress
        {
            get
            {
                int store = 0;
                switch (StoreArea)//通过存储区判断并显示存储位置
                {
                    case "01 Coil Status(0x)":
                        store = 0;
                        break;
                    case "02 Input Status(1x)":
                        store = 1;
                        break;
                    case "03 Holding Register(4x)":
                        store = 4;
                        break;
                    case "04 Input Registers(3x)":
                        store = 3;
                        break;
                    default:
                        store = 4; //默认值
                        break;
                }
                absoluteAddress = (store * 10000 + Convert.ToInt32(Address)).ToString();//30001,40001开始
                return absoluteAddress;
            }
            set
            {
                value = absoluteAddress;
            }
        }
    }
}

建立一个helper

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Text.Json;
using System.Text.Encodings.Web;

namespace Tool
{
    public static class JsonTool
    {
        public static string ToJson<T>(this T obj)
        {
            return JsonSerializer.Serialize(obj, typeof(T),
                new JsonSerializerOptions
                {
                    Encoder = JavaScriptEncoder.UnsafeRelaxedJsonEscaping
                });
        }
    }
}

`System.Text.Json` 是 .NET Core 3.0 及更高版本中引入的一个高性能的、低内存的 JSON 序列化与反序列化库。它是 .NET Core 和 .NET 5/6/7 等新版本中推荐的 JSON 处理方式，因为它比旧的 `Newtonsoft.Json`（通常称为 Json.NET）库在性能上有所提升，并且它是 Microsoft 官方维护的。

System.Text.Json 解析 json
03-18
<think>好的，我现在需要帮助用户了解如何使用System.Text.Json在.NET Core中解析JSON数据。首先，我得回顾一下已有的引用内容，确保回答准确。用户可能是一个开发者，正在迁移项目到.NET Core，或者是从Newtonsoft.Json转过来的，所以需要对比两者吗？不过用户的问题更关注于具体的解析方法，所以应该专注于System.Text.Json的使用步骤。 用户需要的是解析JSON文件或字符串的示例教程。根据引用[3]，里面提到了使用JsonSerializer.Deserialize方法，这可能是一个关键点。引用[2]和[4]提到System.Text.Json是.NET内置的库，可能用户需要知道基本操作而不是第三方库。 首先，解析字符串的话，应该用JsonSerializer.Deserialize<T>(jsonString)。对于文件，可能需要读取文件内容，然后同样反序列化。需要注意异步操作，比如用File.ReadAllTextAsync。此外，引用[1]提到功能差异，可能需要指出一些注意事项，比如大小写敏感或默认设置的不同。 用户可能需要代码示例，所以应该提供解析字符串和文件的例子，包括同步和异步方法。还要提到配置选项，比如PropertyNamingPolicy，这在处理不同命名约定时很重要。例如，JSON属性名是驼峰式，而C#属性是大写，可以用JsonSerializerOptions来处理。 另外，异常处理也很重要，比如捕获JsonException，这样用户知道如何处理无效的JSON数据。可能还需要提到如何处理复杂对象和嵌套结构，但用户的问题可能更基础，所以保持示例简单。 总结步骤：解析字符串的步骤，解析文件的步骤，配置选项，错误处理。引用相关的引用资料，比如引用[3]中的反序列化示例，引用[4]中的内置支持说明。确保代码格式正确，用中文解释每个步骤，并自然添加引用标记。</think>以下是使用 $System.Text.Json$ 解析 JSON 数据的详细步骤和示例： --- ### **1. 解析 JSON 字符串** ```csharp using System.Text.Json; // 示例 JSON 字符串 string jsonString = @"{ ""Name"": ""张三"", ""Age"": 28, ""IsStudent"": false }"; // 定义对应的 C# 类 public class Person { public string Name { get; set; } public int Age { get; set; } public bool IsStudent { get; set; } } // 反序列化操作 Person person = JsonSerializer.Deserialize<Person>(jsonString); Console.WriteLine($"姓名: {person.Name}, 年龄: {person.Age}"); ``` --- ### **2. 解析 JSON 文件** #### 同步读取文件： ```csharp string filePath = "data.json"; string jsonContent = File.ReadAllText(filePath); Person person = JsonSerializer.Deserialize<Person>(jsonContent); ``` #### 异步读取文件（推荐）： ```csharp using System.IO; using System.Threading.Tasks; async Task<Person> ReadJsonFileAsync(string filePath) { using FileStream fileStream = File.OpenRead(filePath); return await JsonSerializer.DeserializeAsync<Person>(fileStream); } ``` --- ### **3. 配置反序列化选项** 若 JSON 属性名与 C# 类属性名不匹配（如驼峰命名法），需配置 $JsonSerializerOptions$： ```csharp var options = new JsonSerializerOptions { PropertyNamingPolicy = JsonNamingPolicy.CamelCase, // 支持驼峰命名 WriteIndented = true // 格式化输出 }; // 使用配置反序列化 Person person = JsonSerializer.Deserialize<Person>(jsonString, options); ``` --- ### **4. 处理复杂对象和嵌套结构** 若 JSON 包含嵌套对象或数组： ```csharp string json = @"{ ""Department"": ""技术部"", ""Employees"": [ { ""Name"": ""李四"", ""Age"": 30 } ] }"; public class Company { public string Department { get; set; } public List<Person> Employees { get; set; } } Company company = JsonSerializer.Deserialize<Company>(json); ``` --- ### **5. 错误处理** 通过 try-catch 捕获无效 JSON 格式异常： ```csharp try { Person person = JsonSerializer.Deserialize<Person>(jsonString); } catch (JsonException ex) { Console.WriteLine($"JSON 解析失败: {ex.Message}"); } ``` --- ### **对比 Newtonsoft.Json** - $System.Text.Json$ 默认 **区分大小写**，而 Newtonsoft.Json 默认不区分[^1] - 性能更高，但功能较少（如无 $JsonConvert.PopulateObject$）[^2] - 内置支持 .NET Core 3.0+，无需安装第三方包[^4] ---
