[WinForm]WinForm之简易权限管理
[摘要]陆续在今年写了固定资产和低值易耗品，采购模具管理以及将要进行的制程管理等子系统，都是各自写一个小程序，每次都要搭建下环境。每做一个小系统部署的时候都得打包一次。干脆做一个简易框架去实现吧。
权限管理仿照自己协同工作平台。
表一：菜单管理
CREATE TABLE [dbo].[WinForm_MenuInfo]( [ID] [int] IDENTITY(1,1) NOT NULL, [NAME] [nvarchar](100) NOT NULL, [PARENTID] [int] NOT NULL, [FORMNAME] [nvarchar](200) NULL, [TYPE] [int] NULL, [SORTINDEX] [int] NULL, CONSTRAINT [PK_WinForm_MenuInfo] PRIMARY KEY CLUSTERED ( [ID] ASC )WITH (PAD_INDEX = OFF, STATISTICS_NORECOMPUTE = OFF, IGNORE_DUP_KEY = OFF, ALLOW_ROW_LOCKS = ON, ALLOW_PAGE_LOCKS = ON) ON [PRIMARY] ) ON [PRIMARY] GO ALTER TABLE [dbo].[WinForm_MenuInfo] ADD CONSTRAINT [DF_WinForm_MenuInfo_PARENTID] DEFAULT ((-1)) FOR [PARENTID] GO ALTER TABLE [dbo].[WinForm_MenuInfo] ADD CONSTRAINT [DF_WinForm_MenuInfo_TYPE] DEFAULT ((0)) FOR [TYPE] GO ALTER TABLE [dbo].[WinForm_MenuInfo] ADD CONSTRAINT [DF_WinForm_MenuInfo_SORTINDEX] DEFAULT ((0)) FOR [SORTINDEX] GO
表二：角色管理
CREATE TABLE [dbo].[WinForm_RoleInfo]( [ID] [int] IDENTITY(1,1) NOT NULL, [NAME] [nvarchar](100) NOT NULL, [DESCRIPT] [nvarchar](500) NULL, [PARENTID] [int] NOT NULL, CONSTRAINT [PK_WinForm_RoleInfo] PRIMARY KEY CLUSTERED ( [ID] ASC )WITH (PAD_INDEX = OFF, STATISTICS_NORECOMPUTE = OFF, IGNORE_DUP_KEY = OFF, ALLOW_ROW_LOCKS = ON, ALLOW_PAGE_LOCKS = ON) ON [PRIMARY] ) ON [PRIMARY] GO
表三：角色菜单
CREATE TABLE [dbo].[WinForm_RoleMenu]( [id] [int] IDENTITY(1,1) NOT NULL, [rid] [int] NOT NULL, [mid] [int] NOT NULL, CONSTRAINT [PK_WinForm_RoleMenu] PRIMARY KEY CLUSTERED ( [id] ASC )WITH (PAD_INDEX = OFF, STATISTICS_NORECOMPUTE = OFF, IGNORE_DUP_KEY = OFF, ALLOW_ROW_LOCKS = ON, ALLOW_PAGE_LOCKS = ON) ON [PRIMARY] ) ON [PRIMARY] GO
菜单管理：
角色授权：
用户角色管理
重点来了：
WINFORM如何加载呢？
简易布局：
顶部标题
左边是树形菜单
右边是TabContorl。
