Dapper連線MySql資料庫
阿新 • • 發佈:2018-12-11
首先通過NuGet在專案中分別安裝Dapper和MySql.Data的引用
PM> Install-Package Dapper -Version 1.40.0 PM> Install-Package MySql.Data -Version 6.7.9
Web.config
<connectionStrings> <add name="MySqlConnectionString" connectionString="Database=mysql_test;Data Source=localhost;User Id=root;Password=123456;CharSet=utf8;port=3306" /> </connectionStrings>
封裝一下Dapper
public class DapperService { public static MySqlConnection MySqlConnection() { string mysqlConnectionString = ConfigurationManager.ConnectionStrings["MySqlConnectionString"].ToString(); var connection = newMySqlConnection(mysqlConnectionString); connection.Open(); return connection; } }
MySql資料庫
User實體
public class User { public int ID { get; set; } public string Name { get; set; } public bool Sex { get; set; }public decimal Age { get; set; } public string Tel { get; set; } public DateTime? ModifyTime { get; set; } }
Select查詢
using (IDbConnection conn = DapperService.MySqlConnection()) { string sqlCommandStr = @"SELECT * FROM USER"; List<User> userList = conn.Query<User>(sqlCommandStr).ToList(); return View(userList); }
Insert插入
public void InsertInfo(User user) { string insertSqlStr = @"INSERT INTO user(Name,Sex,Age,Tel)VALUES(@Name,@Sex,@Age,@Tel)"; using (IDbConnection conn = DapperService.MySqlConnection()) { // conn.Execute(insertSqlStr, new { Name="ssss",Sex=true,Age="22",Tel="2222"}); ///這種是手動賦值 conn.Execute(insertSqlStr, user); //這種是按實體插入 } }
