C#(.NET Core)使用泛型＜T＞实现类型数据缓存方法及示例代码

详细解析这段代码 using Microsoft.Extensions.Configuration; using System; public static class ConfigurationManager { private static readonly Lazy<IConfigurationRoot> _configuration = new(() => new ConfigurationBuilder() .SetBasePath(Application.StartupPath) .AddJsonFile("appsettings.json", optional: false, reloadOnChange: true) .Build()); // 直接通过属性访问配置 private static IConfigurationRoot Configuration => _configuration.Value; // 静态方法获取字符串 public static string GetString(string key) => Configuration[key]; // 静态泛型方法 public static T GetValue<T>(string key) => Configuration.GetValue<T>(key); // 静态版GetSection扩展 public static T GetSection<T>(string sectionName) where T : class, new() => Configuration.GetSection(sectionName).Get<T>(); }
