看下我們上一節搭建的架構，現在開始從事底層的封裝

1、首先需要一個實體的接口IEntity

1 namespace Dinner.Dapper
2 {
3     public interface IEntity<TPrimaryKey>
4     {
5         TPrimaryKey Id { get; set; }
6     }
7 }

2、由於所有的數據庫實體都是有主鍵的，所以這裏定義一個BaseModel，這裏我用的主鍵是Guid，你們可以換成int

1 using System;
2 
3 namespace Dinner.Dapper
 
4 {
5     public class BaseModel : IEntity<Guid>
6     {
7         public Guid Id { get; set; }
8     }
9 }

3、接下來是封裝Dapper的SqlServer配置DataBaseConfig（Redis的配置你們可以忽略）,不要忘記添加Dapper的Nuget包

 1 using StackExchange.Redis;
 2 using System.Data;
 3 using System.Data.SqlClient;
 4 
 5 namespace
 
 Dinner.Dapper
 6 {
 7     public class DataBaseConfig
 8     {
 9         #region SqlServer鏈接配置
10 
11         private static string DefaultSqlConnectionString = @"Data Source=localhost;Initial Catalog=Dinner;User ID=sa;Password=123456;";
12         private static string DefaultRedisString = "
 
localhost, abortConnect=false";
13         private static ConnectionMultiplexer redis;
14 
15         public static IDbConnection GetSqlConnection(string sqlConnectionString = null)
16         {
17             if (string.IsNullOrWhiteSpace(sqlConnectionString))
18             {
19                 sqlConnectionString = DefaultSqlConnectionString;
20             }
21             IDbConnection conn = new SqlConnection(sqlConnectionString);
22             conn.Open();
23             return conn;
24         }
25 
26         #endregion
27 
28         #region Redis鏈接配置
29 
30         private static ConnectionMultiplexer GetRedis(string redisString = null)
31         {
32             if (string.IsNullOrWhiteSpace(redisString))
33             {
34                 redisString = DefaultRedisString;
35             }
36             if (redis == null || redis.IsConnected)
37             {
38                 redis = ConnectionMultiplexer.Connect(redisString);
39             }
40             return redis;
41         }
42 
43         #endregion
44     }
45 }

4、然後是倉儲基接口IRepositoryBase，添加了基本的增刪改查和一個無參的存儲過程

 1 using System;
 2 using System.Collections.Generic;
 3 using System.Threading.Tasks;
 4 
 5 namespace Dinner.Dapper
 6 {
 7     public interface IRepositoryBase<T>
 8     {
 9         Task Insert(T entity, string insertSql);
10 
11         Task Update(T entity, string updateSql);
12 
13         Task Delete(Guid Id, string deleteSql);
14 
15         Task<List<T>> Select(string selectSql);
16 
17         Task<T> Detail(Guid Id, string detailSql);
18 
19         /// <summary>
20         /// 無參存儲過程
21         /// </summary>
22         /// <param name="SPName"></param>
23         /// <param name="args"></param>
24         /// <returns></returns>
25         Task<List<T>> ExecQuerySP(string SPName);
26     }
27 }

5、倉儲基實現類RepositoryBase繼承倉儲基接口，簡單實現增刪改查和無參的存儲過程

 1 using Dapper;
 2 using System;
 3 using System.Collections.Generic;
 4 using System.Data;
 5 using System.Linq;
 6 using System.Threading.Tasks;
 7 
 8 namespace Dinner.Dapper
 9 {
10     public class RepositoryBase<T> : IRepositoryBase<T>
11     {
12         public async Task Delete(Guid Id, string deleteSql)
13         {
14             using (IDbConnection conn = DataBaseConfig.GetSqlConnection())
15             {
16                 await conn.ExecuteAsync(deleteSql, new { Id = Id });
17             }
18         }
19 
20         public async Task<T> Detail(Guid Id, string detailSql)
21         {
22             using (IDbConnection conn = DataBaseConfig.GetSqlConnection())
23             {
24                 //string querySql = @"SELECT Id, UserName, Password, Gender, Birthday, CreateDate, IsDelete FROM dbo.Users WHERE Id=@Id";
25                 return await conn.QueryFirstOrDefaultAsync<T>(detailSql, new { Id = Id });
26             }
27         }
28 
29         /// <summary>
30         /// 無參存儲過程
31         /// </summary>
32         /// <param name="SPName"></param>
33         /// <returns></returns>
34         public async Task<List<T>> ExecQuerySP(string SPName)
35         {
36             using (IDbConnection conn = DataBaseConfig.GetSqlConnection())
37             {
38                 return await Task.Run(() => conn.Query<T>(SPName, null, null, true, null, CommandType.StoredProcedure).ToList());
39             }
40         }
41 
42         public async Task Insert(T entity, string insertSql)
43         {
44             using (IDbConnection conn = DataBaseConfig.GetSqlConnection())
45             {
46                 await conn.ExecuteAsync(insertSql, entity);
47             }
48         }
49 
50         public async Task<List<T>> Select(string selectSql)
51         {
52             using (IDbConnection conn = DataBaseConfig.GetSqlConnection())
53             {
54                 //string selectSql = @"SELECT Id, UserName, Password, Gender, Birthday, CreateDate, IsDelete FROM dbo.Users";
55                 return await Task.Run(()=>conn.Query<T>(selectSql).ToList());
56             }
57         }
58 
59         public async Task Update(T entity, string updateSql)
60         {
61             using (IDbConnection conn = DataBaseConfig.GetSqlConnection())
62             {
63                 await conn.ExecuteAsync(updateSql, entity);
64             }
65         }
66     }
67 }

上面這些就是底層基本的封裝，下一節我們來添加實體和倉儲
