asp.net Core利用Configuration读取自定义配置文件
自定义配置文件:
在根目录建一个Config文件夹和config.json配置文件
{
"Person": {
"Name": "zhangsan2222",
"Age": 18
}
}
Program.cs文件:
namespace WebApplication1
{
public class Program
{
public static void Main(string[] args)
{
CreateWebHostBuilder(args).Build().Run();
}
public static IWebHostBuilder CreateWebHostBuilder(string[] args) =>
WebHost.CreateDefaultBuilder(args)
.ConfigureAppConfiguration((c, h) =>
{
h.AddJsonFile($"Config/config.json",true,true);
})
.UseStartup<Startup>();
}
}
Controller文件:
[Route("[Controller]")]
public class OptionsController : Controller
{
private readonly IConfiguration _configuration;
public OptionsController(IConfiguration configuration)
{
_configuration = configuration;
}
[HttpGet("Index")]
public IActionResult Index()
{
var Name= _configuration.GetValue<String>("Person:Name");
return View(nameof(Index),Name);
}
view文件:
@model String
@{
Layout = null;
}
<!DOCTYPE html>
<html>
<head>
<meta name="viewport" content="width=device-width" />
<title>Index</title>
</head>
<body>
<h1>@Model.ToString()</h1>
</body>
</html>
绑定到实体类:
////第一种绑定
//PersonOptions option = new PersonOptions();
////配置文件绑定Person绑定到该PersonOptions对象上
//Configuration.Bind("Person", option);
////注入
//services.AddSingleton(option);
////第二种绑定
PersonOptions option = new PersonOptions();
Configuration.GetSection("Person").Bind(option);
services.AddSingleton(option);
实体类:
public class PersonOptions
{
public String Name { get; set; }
public int Age { get; set; }
}
controller:
[Route("[Controller]")] public class OptionsController : Controller { private readonly PersonOptions _options; public OptionsController(PersonOptions options) { _options = options; } [HttpGet("Index")] public IActionResult Index() { return View(nameof(Index), _options.Name); } }
