我有一个NetCore控制台应用程序,想要阅读appsettings.json
并将一个部分解析为List<Param>
(没有依赖注入或AspNetCore)。
我已经尝试了How do I bind a multi level configuration object using IConfiguration in a .net Core application?但似乎.Get<T>()
已从netcoreapp1.1
IConfigurationSection myListConfigSection = configurationRoot.GetSection("ListA");
List<Param> paramList;
//Get does not exist
//paramList = myListConfigSection.Get<Param>();
string paramListJson = myListConfigSection.Value // is null
// won't work neither because paramListJson is null
paramList = JsonConvert.DeserializeObject<Param>(paramListJson);
appsettings.json:
{
"ListA": [
{ "ID": "123", "Param": "ABC"},
{ "ID": "123", "Param": "JKS"},
{ "ID": "456", "Param": "DEF"}
]
}
是否有一种简单的方法可以将配置加载到对象中,还是我必须再次阅读配置文件并使用JsonConvert
自行解析?

Get<T>
在包Microsoft.Extensions.Configuration.Binder
