C#关于角色权限系统

1.创建角色权限表

create table t_GroupFormsAuthority(

--FGfaID numeric(6,0) identity primary key ,

FUGroupNo varchar(50) not null ,

FSFormNo varchar(100) not null ,--系统窗口、报表代码

FGfaIsOk char(1) default '1' ,

FStatus char(1) default '1',---

FFlag char(1) default '1',---

FCreateDate datetime default getdate() ,

FCreator varchar(20) null ,

FModifyDate datetime default getdate() ,

FModifier varchar(20) null ,

FMemo text null ,

constraint PK_t_GroupFormsAuthority primary key(FUGroupNo,FSFormNo)

)

go

2.插入数据

Admin MenuItemBase 1 1

Admin MenuItemBase_01 1 1

Admin MenuItemFile 1 1

Admin MenuItemFile_Exit 1 1

Admin MenuItemFile_Print 1 1

Admin MenuItemHelp 1 1

Admin MenuItemWindow 1 1

3、新建项目

1、界面如图，

加入菜单项并命名为:menuMain

2、程序代码：

新建代码文件:setMenu.cs

using System;

using System.Collections.Generic;

using System.Text;

using System.Windows.Forms;

using System.Data;

using DBClassLib;namespace ERP

{

public class SetMenu

{

private MenuStrip msMain; /// <summary>

/// 构造函数

/// </summary>

/// <param name="mMain"></param>

public SetMenu(MenuStrip mMain)

{

msMain = mMain;

msMain.Visible = true;



} /// <summary>

/// 设置菜单权限

/// </summary>

public void SetMenuPower()

{

string strSql;

int mItemCount, i, j;

mItemCount = msMain.Items.Count;

strSql = "SELECT FSFormNo,FGfaIsOk FROM t_GroupFormsAuthority WHERE FStatus='1' AND FUGroupNo='" + Global.userInfo[2] + "'";

DBOperator db = DBOperator.GetDBOperator(Global.strConnection);

DataTable dt = new DataTable();

db.Open();

dt = db.GetDataTable(strSql);

if (dt.Rows.Count > 0)

{

for (i = 0; i < mItemCount; i++)

{

for (j = 0; j < dt.Rows.Count; j++)

{

if ((msMain.Items[i].Name.ToString() == dt.Rows[j]["FSFormNo"].ToString()) && (dt.Rows[j][1].ToString() == "1"))

{

SetMenuItemUsability(msMain.Items[i], true);

GetSubMenu(dt,(ToolStripMenuItem) msMain.Items[i]);

break;

}

else

{

SetMenuItemUsability(msMain.Items[i], false);

}

}

}

}

else

{

msMain.Visible = false;

}

db.Close();

}

private void GetSubMenu(DataTable dt, ToolStripMenuItem tsmItem)//ToolStripItem mItems)

{

//ToolStripMenuItem tsmItem=new ToolStripMenuItem() ;

int i,j,mItemsCount;

mItemsCount = tsmItem.DropDownItems.Count;

if (mItemsCount > 0)

{

for (i = 0; i < mItemsCount; i++)

{

for (j = 0; j < dt.Rows.Count; j++)

{

if (tsmItem.DropDownItems[i].Name == dt.Rows[j][0].ToString() && dt.Rows[j][1].ToString() == "1")

{

SetMenuItemUsability(tsmItem.DropDownItems[i], true);

break; }

else

{

SetMenuItemUsability(tsmItem.DropDownItems[i], false);

}

}

}

}

} /// <summary>

/// 设置菜单可用性

4、主窗口调用:

SetMenu sm=new
SetMenu(menuMain);

sm.SetMenuPower();
