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

{
"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();
}
}
