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:
配置文件结构
1 2 3 4 5 | public class DemoSettings { public string MainDomain { get; set; } public string SiteName { get; set; } } |
appsettings.json中显示效果
1 2 3 4 5 6 7 8 9 10 11 12 13 14 | { "DemoSettings": { "MainDomain": "http://www.mysite.com", "SiteName": "My Main Site" }, "Logging": { "IncludeScopes": false, "LogLevel": { "Default": "Debug", "System": "Information", "Microsoft": "Information" } } } |
配置Services
1 2 3 4 5 | public void ConfigureServices(IServiceCollection services) { // Add framework services. services.AddMvc(); } |
1 2 3 4 5 6 7 8 9 10 11 | 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
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 | 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(); } } |
