By using System.Text, Using Benchmark DotNet.Attributes, using System.Collections.Generic, Using Benchmark DotNet.Order
| freeCodeCamp
Being able to update variables, call particular branches of code, or simply output different code based on a certain condition is a vital part of programming in any language. C# (C Sharp) offers multiple ways to do these things, and I’m about to show you some of the most common ones. We’ll discuss the pros and cons of each method, and which ones are more suited for particular scenarios. Conclusion I will teach you all about the following conditional coding mechanisms within C#.

| cnblogs.com
原文: [A Dive into .Net 8 Native AOT and Efficient Web Development] 作者: [sharmila subbiah] 随着 .NET 8 的发布，微软迈出了重要一步，为 ASP.NET Core 引入了原生的 Ahead-of-Time (AOT) 编译。这一进步不仅提高了应用程序的性能，还简化了开发过程，标志着 .NET 生态系统进入了新的时代。 .NET 8 引入了原生 AOT，这对 Web 开发人员来说是一个重大改变。该技术将 .NET 代码直接编译为原生代码，无需在运行时进行即时 (JIT) 编译。结果如何？启动时间更快、内存占用更少、以及整体改善的应用程序性能升，这对于高流量 Web API 和微服务尤其重要。 .NET 8 引入了一个专门为原生 AOT 设计的全新项目模板 - "ASP.NET Core Web API (native AOT)" 项目模板。 此模板的简称为“webapiaot”，默认启用 AOT 发布。它是为希望从项目一开始就充分利用 AOT...

C# MongoDB Insert Benchmarks - What You Need To Know

|
By Using Benchmark DotNet.Attributes, Using MongoDb.Bson, Using MongoDb.Driver, using Testcontainers.Mongo Db
| DEV Community
In previous articles, I explained how we could use C# and MongoDB to get records inserted. But we started this exploration into MongoDB covering a lot of the basics and I wanted to start looking into more interesting aspects of how we use these things together. As I was putting video content together about all of these topics, one thing that caught my attention was the generic methods vs methods that operated on BsonDocument and I was curious if the performance was any different.

Performance Improvements in .NET 8 & 7 & 6 -- String【翻译】

By Using Benchmark DotNet.Running, using System.Text.Unicode, Using Benchmark DotNet.Attributes, Random NumberGenerator.Fill
| cnblogs.com
原文：https://devblogs.microsoft.com/dotnet/performance-improvements-in-net-8/#strings-arrays-and-spans .NET 8在数据处理领域有了巨大的改进，特别是在有效操作字符串，数组和Span方面。既然我们刚刚谈到了UTF8和IUtf8SpanFormattable，那就从这里开始。 UTF8 如前所述，现在有很多类型实现了IUtf8SpanFormattable。我注意到所有的数值原始类型，DateTime{Offset}，和Guid，以及dotnet/runtime#84556，System.Version类型也实现了它，同样，由于dotnet/runtime#84487，IPAddress和新的IPNetwork类型也实现了它。然而，.NET 8不仅在所有这些类型上提供了这个接口的实现，而且还在一个关键的地方使用了这个接口。 如果你还记得，C# 10和.NET...

By Using Benchmark DotNet.Attributes, using System.Runtime.Interop, using System.Text, namespace Benchmarks.Benchmarks
| pvsm.ru
Уважаемые читатели, в этой статье я хочу рассказать о небольших тестах со строками и представить свои выводы. Тесты сделаны на .net 7. Все коды представлены для повторения но отмечу, что больше всего удивили циклы. Про строки написано немало, поэтому слишком углубляться в их особенности не буду, лишь напомню, что строки в реальности могут быть изменяемыми с использованием различных ухищрений.

【译】.NET 7 中的性能改进（一）

By Using Benchmark DotNet.Attributes, Using Benchmark DotNet.Running, MinOpts code, Gword Ptr
| cnblogs.com
原文 | Stephen Toub 翻译 | 郑子铭 一年前，我发布了.NET 6 中的性能改进，紧接着是.NET 5、.NET Core 3.0、.NET Core 2.1和.NET Core 2.0的类似帖子。我喜欢写这些帖子，也喜欢阅读开发人员对它们的回复。去年的一条评论特别引起了我的共鸣。评论者引用了虎胆龙威的电影名言，“'当亚历山大看到他的领域的广度时，他为没有更多的世界可以征服而哭泣'”，并质疑 .NET 的性能改进是否相似。水井干涸了吗？是否没有更多的“[性能]世界可以征服”？我有点头晕地说，即使 .NET 6 有多快，.NET 7 明确地强调了可以做的和已经做的更多。 与以前版本的 .NET 一样，性能是遍及整个堆栈的关键焦点，无论是明确为性能创建的功能，还是在设计和实现时仍牢记性能的非性能相关功能。现在 .NET 7 候选版本即将发布，现在是讨论其中大部分内容的好时机。在过去的一年中，每次我审查可能对性能产生积极影响的 PR 时，我都会将该链接复制到我维护的期刊中，以便撰写这篇文章。几周前，当我坐下来写这篇文章时，我看到了一份包含近 1000 个影响性能的 PR...

How Has LINQ Performance Enhanced in .NET 7?

|
By Using Benchmark DotNet.Attributes, using System.Collections.Generic, using System.Linq, Using Benchmark DotNet.Running
| DZone Verified
The new version of .NET enhanced the performance of the Min, Max, Average, and Sum methods for arrays and lists. How much do you think their execution speed has increased? Two times or five times? No, they got even faster. Let's see how that was achieved. How Has LINQ Enhanced? LINQ (Language-Integrated Query) is a simple and convenient query language. It allows you to express complex operations in a simple way. Almost every .NET developer uses LINQ.
