}简单取值var architect builder.Configuration.GetSection(AppInfo:Author:Architect).Value;
var features1builder.Configuration.GetSection(AppInfo:Features:1).Value;用record绑定recordpublic record AppInfoRecord(string? Name, string? Version, AuthorRecord? Author, string[]? Features);
public record AuthorRecord(string? Architect, string? Programmer, string? Designer);绑定var authorRecord new AuthorRecord(null, null, null);
var appInfoRecord new AppInfoRecord(null, null, authorRecord, null);
builder.Configuration.GetSection(AppInfo).Bind(appInfoRecord);结果用class绑定classpublic class AppInfo
{public string? Name { get; set; }public string? Version { get; set; }public Author? Author { get; set; }public string[]? Features { get; set; }
}
public class Author
{public string? Architect { get; set; }public string? Programmer { get; set; }public string? Designer { get; set; }
}绑定var appInfo new AppInfo();
builder.Configuration.GetSection(AppInfo).Bind(appInfo);结果用record和class绑定各有优势record定义的时间代码简单绑定要复杂一些class正好相反定义要复杂一些绑定时简单。从IConfiguration中获取配置可以在路由方法中获取配置信息app.MapGet(/getappinfo, (IConfiguration config)
{return config.GetSection(AppInfo:Name).Value;
});从路由中取配置文件首选注入var authorRecord new AuthorRecord(null, null, null);
var appInfoRecord new AppInfoRecord(null, null, authorRecord, null);
builder.Configuration.GetSection(AppInfo).Bind(appInfoRecord);
builder.Services.AddSingleton(appInfoRecord);取配置数据app.MapGet(/appinfo, (AppInfoRecord appinfo)
{return appinfo;
});结果读取其他格式的配置文件myconfig.ini[iniconfig]
key1value1
key2value2加载配置文件并取值builder.Host.ConfigureAppConfiguration((hostingContext, config)
{config.AddIniFile(myconfig.ini,optional: true,reloadOnChange: true);
});var key1builder.Configuration.GetSection(iniconfig:key1).Value;
