.Net Core 读取配置文件 appsettings.json

1. 首先些一个类

?

1 2 3 4 5

public class MySettings {     public string P1 { get; set; }     public string P2 { get; set; } }

2. 在 appsettings.json 中添加配置项

?

1 2 3 4 5 6 7 8 9 10 11 12

{   "Logging": {     "IncludeScopes": false,     "LogLevel": {       "Default": "Warning"     }   },   "MySettings": {     "P1": "p1_value",     "P2": "p2_value"   } }

3. 修改 Startup.cs

?

1 2 3 4 5

public void ConfigureServices(IServiceCollection services) {     services.Configure<MySettings>(Configuration.GetSection("MySettings"));     services.AddMvc(); }

4.  修改 HomeController.cs

public class HomeController : Controller {     private MySettings mySettings { get; set; }       public HomeController(IOptions<MySettings> mySettings)     {         this.mySettings = mySettings.Value;     }       public IActionResult Index()     {         string p1 = mySettings.P1;         return View();     } }
