效果 概述 最近有個小需求要用雙滑塊表示一個取值範圍,於是就簡單做了個用戶控制項,在此記錄下. 使用矩形Rectangle表示範圍,橢圓Ellipse表示滑塊,使用Canvas控制滑塊的左右移動. 橢圓的滑鼠按下事件里強制獲取滑鼠事件焦點,避免移動過快或移出控制項範圍時,滑塊就不跟著跑了.橢圓的滑鼠抬起 ...
一、引言
上一篇.NET ORM框架HiSql實戰-第一章-集成HiSql 已經完成了Hisql的引入,本節就把 項目中的菜單管理改成hisql的方式實現。
菜單管理界面如圖:
二、修改增刪改查相關代碼
1、 在 BaseRepository 倉儲基類中添加 hisql訪問對象:HiSqlClient。這樣 所有繼承了BaseRepository的業務倉儲類都可以使用HiSqlClient操作資料庫。本節中的菜單管理用到的倉儲對象就是:SysMenuRepository
2、修改 SysMenuRepository類中訪問數據的代碼,將所有操作資料庫的地方使用HiSql方式實現。
3、查詢業務:獲取菜單詳情
/// <summary>
/// 獲取菜單詳情
/// </summary>
/// <param name="menuId"></param>
/// <returns></returns>
public SysMenu SelectMenuById(int menuId)
{
//hisql方式
return ContextHiSql.HiSql(@"select * from sys_menu where menuId = @menuId ", new { menuId = menuId })
.ToList<SysMenu>().FirstOrDefault();
//sqlsuar方式
return Context.Queryable<SysMenu>().Where(it => it.menuId == menuId).Single();
}
4、修改業務:編輯菜單
/// <summary>
/// 編輯菜單
/// </summary>
/// <param name="menu"></param>
/// <returns></returns>
public int EditMenu(SysMenu menu)
{
//hisql方式
return ContextHiSql.Update("sys_menu", menu).ExecCommand();
//sqlsugar方式
return Context.Updateable(menu).ExecuteCommand();
}
5、刪除業務:刪除菜單
/// <summary>
/// 刪除菜單
/// </summary>
/// <param name="menuId"></param>
/// <returns></returns>
public int DeleteMenuById(long menuId)
{
//hisql方式
return ContextHiSql.Delete("sys_menu").Where(new Filter { { "menuId", OperType.EQ, menuId } }).ExecCommand();
//sqlsugar方式
return Context.Deleteable<SysMenu>().Where(it => it.menuId == menuId).ExecuteCommand();
}
6、新增業務:添加菜單
/// <summary>
/// 添加菜單
/// </summary>
/// <param name="menu"></param>
/// <returns></returns>
public int AddMenu(SysMenu menu)
{
var Db = Context;
menu.Create_time = Db.GetDate();
menu.menuId = IDHelper.GetLongId();
//hisql方式
return ContextHiSql.Insert("sys_menu", menu).ExecCommand();
//sqlsugar方式
return Db.Insertable(menu).ExecuteCommand();
}
Tip:此處使用雪花ID,其實HiSql自帶相關方法。如 HiSql.Snowflake.NextId(); 以及業務根據業務實際情況自定義編號的模塊,後面再集成到項目中來。 自定義編號
其他業務方法見 SysMenuRepository 代碼。
