C# 读取屏幕上appsetting.json文件中的所有数组值，并读取id=555的书籍信息

在appsettings.json中

{
  "Logging": {
    "LogLevel": {
      "Default": "Information",
      "Microsoft": "Warning",
      "Microsoft.Hosting.Lifetime": "Information"
    }
  },
  "AllowedHosts": "*",
  "book": [
    {
      "id": "555",
      "language": "C",
      "edition": "First",
      "author": "Dennis Ritchie "
    },
    {
      "id": "666",
      "language": "C#",
      "edition": "Second",
      "author": "Anders Hejlsberg"
    }
  ]
}

在Startup.cs中，我只通过索引获取一个值，下面是我通过id获取的值

    public void Configure(IApplicationBuilder app, IWebHostEnvironment env)
    {
        if (env.IsDevelopment())
        {
            app.UseDeveloperExceptionPage();
        }
        app.Run(async (context) =>
        {
            await context.Response.WriteAsync(Configuration.GetSection("book:0:id").Value);
        });
    }

上面有我的代码，我只得到一个值，如何得到所有数组？

谢谢

您可以尝试以下方法：

var list = new List<MyBookClass>();
Configuration.GetSection("book").Bind(list);
foreach(var book in list)
{ 
   //do what ever you want with your list of books
}

public class MyBookClass
{
   public string id { get; set; }
   public string language { get; set; }
   public string edition { get; set; }
   public string author { get; set; }
}

这是在asp.net core中读取设置的常见模式

然后你可以对列表做任何你想做的事情
