C# Lazy Loading 前言 按需加载对象延迟加载实际是推迟进行创建对象,直到对其调用后才进行创建初始化,延迟(懒加载)的好处是提高系统性能,避免不必要的计算以及不必要的资源浪费。 常规有这些情况: 对象创建成本高且程序可能不会使用它。 例如,假定内存中有具有 Orders 属性的 Customer 对象,该对象包含大量 Order 对象,...

Use a CDN: When web content is cached in a CDN, communication with the origin server is kept to a minimum whether lazy loading is used or not. CDNs also deliver content to users more quickly because they are usually closer to the user than the origin server. Optimize images: Overly larg...
懒加载(Lazy Loading)是一种设计模式,它允许你将对象的创建推迟到实际需要的时候进行。在C#中,Lazy<T>类实现了这个模式。当你使用Lazy<T>时,它会推迟目标对象的创建直到你第一次访问Lazy<T>的Value属性。这样,你可以在程序运行时避免不必要的初始化和资源消耗,提高性能。 具体原理是,Lazy<T>内部使用了一个委托...
HTTP/3’s Potential:The new HTTP/3 protocol has features that could streamline resource prioritization, potentially making lazy loading even easier to implement. Integration with Image CDNs:Image CDNs already focus on optimization and delivery. They could leverage lazy loading on a larger scale, wi...
Eager loadingmeans that the related data is loaded from the database as part of the initial query. Explicit loadingmeans that the related data is explicitly loaded from the database at a later time. Lazy loadingmeans that the related data is transparently loaded from the database when the nav...
创建Ionic 工程:ionic start LazyLoadingDemo tabs 以修改 `Home` Tab 为例,来实现 Lazy Loading。 1.在 app.module.ts 中: 移除declarations,entryComponents 中的 HomePage,并移除 import { HomePage } from '../pages/home/home'。 2. 新建 home.module.ts: ...
Lazy loading images offers several significant advantages, here are some of them: Faster Page Load: Lazy loading significantly reduces the initial page load time by loading only the images within the user’s viewport, leading to a quicker and more responsive website. Optimized Resource Usage: It...
