更新時間：2023年03月30日 11:22:18 作者：大熊程序猿

本文主要介紹了mysql批量插入BulkCopy的實現(xiàn)，文中通過示例代碼介紹的非常詳細，對大家的學習或者工作具有一定的參考學習價值，需要的朋友們下面隨著小編來一起學習學習吧

一、新建項目：SqlSugarDemo

  <ItemGroup>
    <PackageReference Include="SqlSugarCore" Version="5.1.3.52" />
  </ItemGroup>

二、連接串未添加AllowLoadLocalInfile=true

中文提示 : BulkCopy MySql連接字符串需要添加 AllowLoadLocalInfile=true; 添加后如果還不行Mysql數(shù)據(jù)庫執(zhí)行一下 SET GLOBAL local_infile=1
English Message : connection string add : AllowLoadLocalInfile=true

show global variables like 'local_infile';
SET GLOBAL local_infile=1

三、Startup.cs

using Microsoft.AspNetCore.Builder;
using Microsoft.AspNetCore.Hosting;
using Microsoft.Extensions.Configuration;
using Microsoft.Extensions.DependencyInjection;
using Microsoft.Extensions.Hosting;
using SqlSugar;
using System;
using System.Collections.Generic;
using System.Linq;
using System.Threading.Tasks;
 
namespace WebApplication3
{
    public class Startup
    {
        public Startup(IConfiguration configuration)
        {
            Configuration = configuration;
        }
 
        public IConfiguration Configuration { get; }
 
        // This method gets called by the runtime. Use this method to add services to the container.
        public void ConfigureServices(IServiceCollection services)
        {
            services.AddSingleton<ISqlSugarClient>(s =>
            {
                SqlSugarScope sqlSugar = new SqlSugarScope(new ConnectionConfig()
                {
                    DbType = SqlSugar.DbType.MySql,
                    ConnectionString = "Server=192.168.31.132;User ID=root;Password=123456;Database=sugar;port=3306;AllowLoadLocalInfile=true",
                    IsAutoCloseConnection = true,
                },
               db =>
               {
                   //單例參數(shù)配置，所有上下文生效
                   db.Aop.OnLogExecuting = (sql, pars) =>
                   {
                   };
               });
                return sqlSugar;
            });
 
            services.AddControllersWithViews();
        }
 
        // This method gets called by the runtime. Use this method to configure the HTTP request pipeline.
        public void Configure(IApplicationBuilder app, IWebHostEnvironment env)
        {
            if (env.IsDevelopment())
            {
                app.UseDeveloperExceptionPage();
            }
            else
            {
                app.UseExceptionHandler("/Home/Error");
            }
            app.UseStaticFiles();
 
            app.UseRouting();
 
            app.UseAuthorization();
 
            app.UseEndpoints(endpoints =>
            {
                endpoints.MapControllerRoute(
                    name: "default",
                    pattern: "{controller=Home}/{action=Index}/{id?}");
            });
        }
    }
}

HomeController.cs

using Microsoft.AspNetCore.Mvc;
using Microsoft.Extensions.Logging;
using SqlSugar;
using System;
using System.Collections.Generic;
using System.Diagnostics;
using System.Linq;
using System.Threading.Tasks;
using WebApplication3.Models;
 
namespace WebApplication3.Controllers
{
    public class HomeController : Controller
    {
        private readonly ILogger<HomeController> _logger;
        private readonly ISqlSugarClient _sqlSugarClient;
        public HomeController(ILogger<HomeController> logger, ISqlSugarClient sqlSugarClient)
        {
            _logger = logger;
            _sqlSugarClient = sqlSugarClient;
        }
 
        public IActionResult Index()
        {
            _sqlSugarClient.Fastest<RealmAuctionDatum>().BulkCopy(GetList());
            return View();
        }
        public List<RealmAuctionDatum> GetList()
        {
            var datas = new List<RealmAuctionDatum>();
            for (int i = 0; i < 10000; i++)
            {
                datas.Add(new RealmAuctionDatum { Name = Guid.NewGuid().ToString("N") });
            }
            return datas;
        }
    }
}
