使用 System.Linq; 使用 System.Net; 命名空间 Hotspot.Api { /// < summary > /// 此类允许您检索当您只知道其MAC地址时，本地网络上特定计算机的IP地址和主机名。 /// < / summary > public class IPInfo { public IPInfo（ string macAddress， string ipAddress） { this .MacAddress = macAddress;

} catch （例外） {} } return hostName; } } #region静态方法 /// < 摘要 > /// 使用指定的MAC地址检索本地网络上的计算机的IPInfo。 /// < / summary > /// < param name =macAddress > MAC要检索的IPInfo的地址。< / param > ; /// < 返回 > < / returns > public static IPInfo GetIPInfo（ string macAddress） { var ipinfo =（ from ip in IPInfo.GetIPInfo （） 其中 ip.MacAddress.ToLowerInvariant（）== macAddress.ToLowerInvariant（） 选择 ip）.FirstOrDefault（）;

foreach （ var arp in splitted） { // 解析所有MAC / IP地址组合 if （！string.IsNullOrEmpty（arp）） { var pieces =（ from piece in arp.Split（ new char [] {' ' ，' \t'}） where ！string.IsNullOrEmpty（piece） select piece）.ToArray（）; if （pieces.Length == 3 ） { list.Add（ new IPInfo（件[ 1 ]，件[ 0 ]））; } } } // 返回包含MAC / IP地址组合的IPInfo对象列表 return 列表; } catch （例外情况） { throw new 异常（ IPInfo：Error Parsing'arp -a'结果'，ex）; } } /// < 摘要 > /// 这将在Windows中运行arp实用程序以检索所有MAC / IP地址条目。 /// < / summary > /// < 返回 > < / returns > private static string GetARPResult（） {流程p = null ; string output = string .Empty; 尝试 {p = Process.Start（ new ProcessStartInfo（ arp， - ） { CreateNoWindow = true ， UseShellExecute = false ， RedirectStandardOutput = true }）; output = p.StandardOutput.ReadToEnd（）; p.Close（）; } catch （例外情况） { throw new 异常（ IPInfo：错误检索'arp -a'结果'，ex）; } 最后 { 如果（p ！= null ） { p.Close（）; } } return 输出; } #endregion } } 所以这是代码 它会自动解析主机名ip地址也是。 但是我需要它自动解析主机名，但手动输入ip地址为ex = Textbox1.text = 192.168。 21.4 请帮助解决方案 为了设置IP要使用系统中任何设备的地址，您需要成为网段的DHCP主机 - 其中包括示例中192.168.21.xxx区域的所有设备。如果不是，那么两个设备很容易被赋予相同的IP地址，这将导致很多问题。而且这个角色通常是给路由器或类似的设备，而不是特定的PC（虽然它可以）。 所以首先看看你的本地网络，并确定DHCP服务器 - 你会必须与它沟通才能做到这一点。 我希望你有充分的理由这样做，而且听起来好像没有很多奖励！ HeyHow can i set a ip address of devices connected to pc hotspot manually in c#I tried to find it on google but found this oneIt gets ip but automaticallyhere is the codeusing System;using System.Collections.Generic;using System.Diagnostics;using System.Linq;using System.Net;namespace Hotspot.Api{/// <summary>/// This class allows you to retrieve the IP Address and Host Name for a specific machine on the local network when you only know it's MAC Address./// </summary>public class IPInfo{public IPInfo(string macAddress, string ipAddress){this.MacAddress = macAddress;this.IPAddress = ipAddress;}public string MacAddress { get;

If it wasn't, then two devices could easily be given the same IP address and that would cause a lot of problems. And that role is normally given to a router or similar equipment, rather than a specific PC (although it can be).So start by looking at your local network, and identify the DHCP server - you will have to communicate with it to do this.I hope you have a good reason for this, and it sounds like a lot of work for not a lot of reward! 这篇关于在c＃中手动设置连接到pc热点的设备的IP地址的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持！ 上岸，阿里云！
