Asp.Net Core 配置文件

一 创建ConfigurationManager类

public class ConfigurationManager
{
public readonly static IConfiguration Configuration;
static ConfigurationManager()
{
Configuration = new ConfigurationBuilder().SetBasePath(Directory.GetCurrentDirectory()).AddJsonFile("appsettings.json", optional: true).Build();
}

}

二 控制器内读取方式

public class HomeController : Controller
{

public IActionResult Index()
{
//读取
string str=ConfigurationManager.Configuration["Logging:LogLevel:Default"];
return View();
}
}
