本篇內容主要講解“.NET如何使用Hisql實現菜單管理”，感興趣的朋友不妨來看看。本文介紹的方法操作簡單快捷，實用性強。下面就讓小編來帶大家學習“.NET如何使用Hisql實現菜單管理”吧!
菜單管理界面如圖：
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操作數據庫。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，將所有操作數據庫的地方使用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，后面再集成到項目中來。 自定義編號
其他業務方法見 SysMenuRepository 代碼。
