前言
最近在研究把asp.net程序移植到linux上,正好.net core出来了,就进行了学习。
移植代码基本顺利,但是发现.net core中没有ConfigurationManager,无法读写配置文件,单独写个xml之类的嫌麻烦,就谷歌了下,发现了个方法,遂记录如下,方便以后查找:
方法如下
配置文件结构
public class DemoSettings{ public string MainDomain { get; set; } public string SiteName { get; set; }}
appsettings.json中显示效果
appsettings.json
{ "DemoSettings": { "MainDomain": "http://www.mysite.com", "SiteName": "My Main Site" }, "Logging": { "IncludeScopes": false, "LogLevel": { "Default": "Debug", "System": "Information", "Microsoft": "Information" } }}
配置Services
原配置
public void ConfigureServices(IServiceCollection services){ // Add framework services. services.AddMvc();}
自定义
public void ConfigureServices(IServiceCollection services){ // Add framework services. services.AddMvc(); // Added - uses IOptions<T> for your settings. services.AddOptions(); // Added - Confirms that we have a home for our DemoSettings services.Configure<DemoSettings>(Configuration.GetSection("DemoSettings"));}
然后把设置注入进相应的Controller后就可以使用了
public class HomeController : Controller{ private DemoSettings ConfigSettings { get; set; } public HomeController(IOptions<DemoSettings> settings) { ConfigSettings = settings.Value; } public IActionResult Index() { ViewData["SiteName"] = ConfigSettings.SiteName; return View(); }}
总结
