 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();
        }
