c# 用VUE+elmentPlus生成简单管理系统

1. 首先安装依赖

npm install vue@next element-plus @element-plus/icons-vue

2. 主界面布局组件 (MainLayout.vue)

<template>
  <div class="main-layout">
    <!-- 侧边栏 -->
    <el-aside :width="sidebarWidth" class="sidebar">
      <!-- Logo区域 -->
      <div class="logo">
        <img src="/favicon.ico" alt="Logo" v-if="!isCollapse" />
        <span v-if="!isCollapse">管理系统</span>
        <span v-else>系统</span>
      </div>

      <!-- 菜单 -->
      <el-menu

3. 路由配置 (router/index.js)

import { createRouter, createWebHistory } from 'vue-router'
import MainLayout from '@/components/MainLayout.vue'

const routes = [
  {
    path: '/',
    redirect: '/dashboard'
  },
  {

    component: MainLayout,
    children: [

        path: 'dashboard',
        name: 'Dashboard',
        component: () => import('@/views/Dashboard.vue'),
        meta: { title: '仪表盘' }
      },
      {
        path: 'user/list',
        name: 'UserList',
        component: () => import('@/views/user/UserList.vue'),
        meta: { title: '用户列表' }
      },
      {
        path: 'user/roles',
        name: 'UserRoles',
        component: () => import('@/views/user/Roles.vue'),

      },
      {
        path: 'content/categories',
        name: 'Categories',
        component: () => import('@/views/content/Categories.vue'),

        name: 'Tags',
        component: () => import('@/views/content/Tags.vue'),

      },
      {

        name: 'Profile',
        component: () => import('@/views/Profile.vue'),

const router = createRouter({
  history: createWebHistory(),

})

export default router

4. 示例页面组件 (views/Dashboard.vue)
