EF批量插入数据（Z.EntityFramework.Extensions）

EF用原生的插入数据方法DbSet.ADD()和 DbSet.AddRange()都很慢。所以要做大型的批量插入只能另选它法。

1.Nugget

2.代码

using EF6._0Test.EF;
using System;
using System.Collections.Generic;
using System.Diagnostics;
using System.Linq;

namespace EF6._0Test
{
    class Program
    {
        static void Main(string[] args)
        {
            using (Jason_TestEntities db = new Jason_TestEntities())
            {
                List<wolf_example> list = new List<wolf_example>();
                for (int i = ; i < ; i++)
                {
                    list.Add(new wolf_example()
                    {
                        type = i,
                        Name = "Name" + i.ToString(),
                        Money = i,
                        CTime = DateTime.Now,
                        UserID = i,
                        Remak = "Remak" + i.ToString(),
                        Sex = i,
                        IsShow = true,
                    });
                }
                Stopwatch watch = Stopwatch.StartNew();
                db.BulkInsert(list);
                db.BulkSaveChanges();
                watch.Stop();
                Console.WriteLine(string.Format("{0} 条数据, 用时 {1} milliseconds.", list.Count(), watch.ElapsedMilliseconds));
                Console.ReadLine();
            }
        }

    }
}
