在C#编程语言中，提取URL中的域名是一种常见的需求。域名是一个URL的核心部分，表示网站的唯一标识符。本文将介绍一种用于提取URL中域名的算法，并提供相应的C#源代码示例。
算法设计思路：
提取URL中的域名可以通过解析URL字符串来实现。一种常见的方式是使用正则表达式来匹配URL中的域名部分。以下是一个简单的算法设计思路：
下面是使用C#实现提取URL中域名的示例代码：
using System;
using System.Text.RegularExpressions;
class Program

基于51单片机的通讯聊天系统
通过编写51单片机通讯聊天程序，掌握51单片机的各个模块的知识点和运用C语言编写51单片机的能力。用51单片机与口袋开发板设计实现一个单片机与电脑串口助手实现通讯功能的程序。程序的主要功能如下： 1 OLED初始化显示Welcome to Bluetooth communication! 字符串。 2 程序开始时处于接收信息模式, 电脑串口助手发送信息时，将从初始化字符第一个开始显示，电脑串口助手发送信息后，蜂鸣器响铃2秒左右。 3 每次同时按下左右键时，可以轮流切换接收/发送信息模式 4 在发送信息模式时

AI 智能体（Agent）应用开发工程师 · 进阶面试 （五）
在有多位 Agent 共同参与决策时（如评审委员会、代码审查小组），它们可能提出截然相反的建议。共识机制就是用来在这种冲突中得出唯一行动方案的规则。常用机制：多数投票：每个 Agent 一票，根据投票结果决定。实现简单，但忽略了专业度差异。加权投票：根据 Agent 的角色重要性或历史表现赋予不同权重，例如首席架构师 Agent 的票权重是普通开发者 Agent 的 2 倍。管理者仲裁：由一个权限更高的 Manager Agent 听取各方理由后做出最终裁决。这类似于层级制组织决策。辩论收敛。
基于物联网设计温室水培系统(NBIOT+华为云IOT)_338
本项目设计并实现了一套基于物联网的温室水培系统。系统以STM32F103RCT6单片机为核心控制器，结合SHT30温湿度传感器、SGP30二氧化碳传感器、BH1750光照传感器及液位检测传感器等硬件，实现对温室内环境参数的实时采集。系统支持自动和手动两种控制模式，能够根据传感器数据自动控制补光灯、通风风扇、遮光卷帘、降温水帘及营养液补充电机。通过NBIoT模块，系统可将采集的数据通过MQTT协议上传至华为云IOT平台，用户可通过Android手机APP或Windows上位机进行远程监控与控制。
