Dapper学习笔记（4）-事务

Dapper中对事务的处理也非常简单，如下代码所示：

         private void DapperTransaction()
         {
             using (IDbConnection con = OpenConnection())
             {
                 IDbTransaction tran = con.BeginTransaction();
                 try
                 {
                     string query = "update T_Role set RoleName='开发主管' where RoleId=4";//更新一条记录
                     con.Execute(query, null, tran, null, null);
                     //throw new Exception();
                     query = "delete from T_Role where RoleId=8";//删除一条记录
                     con.Execute(query, null, tran, null, null);
                     tran.Commit();
                 }
                 catch (Exception ex)
                 {
                     tran.Rollback();
                 }
             }
         }
