     C#代码

    public class SQLiteContext : DbContext
        {
            public DbSet<Model.manager> manager { get; set; }
    
            public SQLiteContext() : base("connectionSQLite")
            {
    
            }
            protected override void OnModelCreating(DbModelBuilder modelBuilder)
            {
                //清除自动生成的数据表名被复数的问题
                modelBuilder.Conventions.Remove<System.Data.Entity.ModelConfiguration.Conventions.PluralizingTableNameConvention>();
                //自定义表名
                modelBuilder.Entity<Model.manager>().ToTable("dt_manager");
            }
        }
    

     自定义表明方法二

    引用命名空间
    using System.ComponentModel.DataAnnotations; using System.ComponentModel.DataAnnotations.Schema; 类名头部添加 [Table("dt_manager")] public partial class manager

    调用

    private void Window_Loaded(object sender, RoutedEventArgs e)
            {
                SQLiteContext context = new SQLiteContext();
                var manager = context.manager.Where(p => p.id == 1).FirstOrDefault();
            }
