mysql数据库配置(一)

最简单的数据库上下文类

    public class MyDbContext : DbContext
    {
        private static readonly LoggerFactory _loggerFactory = new LoggerFactory(new[] { new DebugLoggerProvider() });
        private string? _connectionStrings;

        public MyDbContext(IConfiguration configuration)
        {
            _connectionStrings = configuration["Database:ConnectionStrings"];
        }

        public DbSet<User> Users { get; set; }

        protected override void OnConfiguring(DbContextOptionsBuilder optionsBuilder)
        {
　　　　　　　　//ServerVersion.AutoDetect(_connectionStrings) 自动检测数据库版本
            optionsBuilder.UseMySql(_connectionStrings, ServerVersion.AutoDetect(_connectionStrings), null);
        }
    }
