1、权限概述
在应用软件中，通常将软件的功能分为若干个子程序，通过主程序调用。那么，通过众多客户来说，如果设置各人的权限呢?软件系统的权限控制几乎是非常常见且必备的，这篇文章整理下常见的九种模型，几乎基本够你用了，主流的权限模型主要有以下9种：
1、ACL模型
访问控制列表
2、DAC模型
自主访问控制
3、MAC模型
强制访问控制
4、ABAC模型
基于属性的访问控制，更灵活复杂
5、RBAC模型
基于角色的权限访问控制，最常用
6、TBAC模型
基于任务和工作流的访问控制
7、T-RBAC模型
基于任务和角色的访问控制
8、OBAC模型
基于对象的访问控制
9、UCON模型
使用控制模型
2、权限实现
本项目没有采用复杂的权限管理，只采用最简单的操作方法，具体是根据不同角色隐藏或显示菜单，具体实现方法是：
1）创建转换器对象
using System;
using System.Collections.Generic;
using System.Globalization;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Windows;
using System.Windows.Data;namespace West.StoreMgr.Helper.Converter
{/// <summary>/// 菜单权限转换器/// </summary>public class AdminVisibleConverter : IValueConverter{public object Convert(object value, Type targetType, object parameter, CultureInfo culture){if (value == null) return Visibility.Collapsed;if (int.TryParse(value.ToString(), out int index)){return index == 0 ? Visibility.Visible : Visibility.Collapsed;}else{return Visibility.Collapsed;}}public object ConvertBack(object value, Type targetType, object parameter, CultureInfo culture){throw new NotImplementedException();}}
}
2、主界面引入转换器
