mysql批量插入数据的基类

自己设计的一个mysql数据库批量添加数据的基类。用于批量向mysql数据库添加数据，子类实现起来很简单，自测性能也还不错。

1、基类实现-BatchAddBase

 using System.Collections.Generic;
 using System.Text;

 namespace MysqlBatchAdd
 {
     public abstract class BatchAddBase<T> where T : class, new()
     {
         /// <summary>
         /// 插入语句的头部
         /// </summary>
         protected abstract string InsertHead { get; }

         /// <summary>
         /// 出入语句的执行体
         /// </summary>
         protected List<string> InsertBodyList { get; set; } = new List<string>();
         /// <summary>
         /// 缓存的sql语句长度
         /// </summary>
         public int SqlCacheLengh { get; set; } =  * ;

         /// <summary>
         /// 批量添加的方法
         /// </summary>
         /// <param name="m"></param>
         public abstract void BatchAdd(T m);

         /// <summary>
         /// 执行添加
         /// </summary>
         public virtual void ExecuteBatchAdd()
         {
             StringBuilder sqlCache = new StringBuilder();

             foreach (string insertBody in InsertBodyList)
             {
                 sqlCache.Append(insertBody + ",");

                 if (sqlCache.Length >= SqlCacheLengh)
                 {
                     sqlCache.Remove(sqlCache.Length - , );
                     MySqlHelper.ExecuteNonQuery(this.InsertHead + sqlCache.ToString());
                     sqlCache.Clear();
                 }
             }

             if (sqlCache.Length > )
             {
                 sqlCache.Remove(sqlCache.Length - , );
                 MySqlHelper.ExecuteNonQuery(this.InsertHead + sqlCache.ToString());
                 sqlCache.Clear();
             }
         }
         /// <summary>
         /// 清楚缓存
         /// </summary>
         public void ClearInsertBody()
         {
             this.InsertBodyList.Clear();
         }
     }
 }

2、一个简单的子类实现-PersonAddHelper

 namespace MysqlBatchAdd
 {
     public class PersonAddHelper : BatchAddBase<Person>
     {
         protected override string InsertHead
         {
             get
             {
                 return @"insert into person(
 name) values ";
             }
         }

         public override void BatchAdd(Person m)
         {
             this.InsertBodyList.Add($@" (
 '{m.name}')");
         }
     }
 }

3、控制台项目，使用示例

 static void Main(string[] args)
         {
             PersonAddHelper personAddHelper = new PersonAddHelper();

             Stopwatch watch = new Stopwatch();

             watch.Start();

             int amount = ;

             for (int i = ; i <= amount; i++)
             {
                 personAddHelper.BatchAdd(new Person() { name = i + "号" });
             }

             personAddHelper.ExecuteBatchAdd();

             watch.Stop();

             Console.WriteLine($"成功插入 {amount} 条数据，用时：{watch.ElapsedMilliseconds} ms");

             Console.ReadKey();
         }
