C# 将appsettings.json映射到类

我正在尝试将appsettings.json转换为C#class

我使用

Microsoft.Extensions.Configuration

从appsettings.json读取配置

 "Settings": {
  "property1": "ap1",
  "property2": "ap2"
 },

我使用反射编写以下代码，但我正在寻找更好的解决方案

foreach (var (key, value) in configuration.AsEnumerable())
{
    var property = Settings.GetType().GetProperty(key);
    if (property == null) continue;
    
    object obj = value;
    if (property.PropertyType.FullName == typeof(int).FullName)
        obj = int.Parse(value);
    if (property.PropertyType.FullName == typeof(long).FullName)
        obj = long.Parse(value);
    property.SetValue(Settings, obj);
}

从appsettings.json文件生成配置：

然后添加Microsoft.Extensions.Configuration.Binder nuget包。您将拥有将配置（或配置节）绑定到现有或新对象的扩展

例如，您有一个设置类（顺便说一句，按照惯例，它被称为选项）

和appsettings.json

 "Settings": {
  "property1": "ap1",
  "property2": "ap2"
 },

要将配置绑定到新对象，可以使用扩展方法：

var settings = config.Get<Settings>();

您可以使用

Dictionary

获取json，然后使用

JsonSerializer

转换json

public IActionResult get()
    {
        Dictionary<string, object> settings = configuration
        .GetSection("Settings")
        .Get<Dictionary<string, object>>();
        string json = System.Text.Json.JsonSerializer.Serialize(settings);

        var setting = System.Text.Json.JsonSerializer.Deserialize<Settings>(json);

        return Ok();
    }

在appsettings.json中

 "Settings": {
  "property1": "ap1",
  "property2": "ap2"
 },

没有获取和绑定method@AliRezaBeigy然后错过了添加Microsoft.Extensions.Configuration.Binder包的部分

public IActionResult get()
    {
        Dictionary<string, object> settings = configuration
        .GetSection("Settings")
        .Get<Dictionary<string, object>>();
        string json = System.Text.Json.JsonSerializer.Serialize(settings);

        var setting = System.Text.Json.JsonSerializer.Deserialize<Settings>(json);

        return Ok();
    }

public class Settings
{
    public string property1 { get; set; }
    public string property2 { get; set; }
}

 "Settings": {
  "property1": "ap1",
  "property2": "ap2"
 },
