建档操作如ping，查询本机主机ip，同步异步查询局域网内主机，同步异步邮件发送等
1）ping
通过ping类测试网络
using System; using System.Text; using System.Net.NetworkInformation; namespace PingExec { class Program { static void Main(string[] args) { Ping ping = new Ping(); PingOptions opt = new PingOptions(); opt.DontFragment = true; string data = "aaaaaaaaaaaaaaa"; byte[] buffer = Encoding.Default.GetBytes(data); int timeout = 120; PingReply replay = ping.Send("192.168.1.101", timeout, buffer, opt); string result = ""; if(replay.Status==IPStatus.Success) { result = "Address:{0}\r\nRoundTrip time:{1}\r\nTime to live:{2}\r\nDont fragment:{3}\r\n" + "Buffer size:{4}"; string str = string.Format(result, replay.Address.ToString(), replay.RoundtripTime, replay.Options.Ttl, replay.Options.DontFragment, replay.Buffer.Length); Console.WriteLine(str); } Console.ReadKey(); } } }
2）查询本机ip与主机名
using System; using System.Net; using System.Diagnostics; using System.Net.Sockets;
（一）通过Process类调用ipconfig.exe
public static string GetIp() { Process cmd = new Process(); cmd.StartInfo.FileName = "ipconfig.exe";//设置程序名 cmd.StartInfo.Arguments = "/all"; //参数 cmd.StartInfo.RedirectStandardOutput = true; cmd.StartInfo.RedirectStandardInput = true; cmd.StartInfo.UseShellExecute = false; cmd.StartInfo.CreateNoWindow = true;//不显示窗口（控制台程序是黑屏） cmd.Start(); string info = cmd.StandardOutput.ReadToEnd(); cmd.WaitForExit(); cmd.Close(); return info; }
（二）通过DNS类获取
static string GetLocalIp() { try { string HostName = Dns.GetHostName(); //得到主机名 IPHostEntry IpEntry = Dns.GetHostEntry(HostName); for (int i = 0; i < IpEntry.AddressList.Length; i++) { //从IP地址列表中筛选出IPv4类型的IP地址 //AddressFamily.InterNetwork表示此IP为IPv4, //AddressFamily.InterNetworkV6表示此地址为IPv6类型 if (IpEntry.AddressList[i].AddressFamily == AddressFamily.InterNetwork) { return IpEntry.AddressList[i].ToString(); } } return ""; } catch (Exception ex) { // MessageBox.Show("获取本机IP出错:" + ex.Message); return ""; } }
IpEntry.AddressList中包含所有ip，包括ip6，ip4（包括无线Ip4）
3）搜索局域网内可ping通的主机
搜索网段范围内所有Ip并测试。
using System; using System.Collections.Generic; using System.Linq; using System.Net; using System.Net.NetworkInformation; using System.Text;
（一）非异步操作
public static void SearchIP() { List<string> ipList = new List<string>(); //获取本地机器名 string myHostName = Dns.GetHostName(); //获取本机IP string myHostIP = Dns.GetHostEntry(Dns.GetHostName()).AddressList.FirstOrDefault<IPAddress>(a => a.AddressFamily.ToString().Equals("InterNetwork")).ToString(); Console.WriteLine(myHostIP); //截取IP网段 string ipDuan = myHostIP.Remove(myHostIP.LastIndexOf(‘.‘)); //MessageBox.Show(ipDuan); //枚举网段计算机 Ping myPing = new Ping(); string pingData = "aaaaaaaaaaaa"; byte[] buffer = Encoding.ASCII.GetBytes(pingData); for (int i = 1; i <= 255; i++) { string pingIP = ipDuan + "." + i.ToString(); PingReply pingReply = myPing.Send(pingIP, 120, buffer); if (pingReply.Status == IPStatus.Success) { ipList.Add(pingIP); //Console.Write("答复的主机地址：" + pingReply.Address.ToString() + " "); //Console.Write("往返时间：" + pingReply.RoundtripTime.ToString() + " "); //Console.Write("生存时间：" + pingReply.Options.Ttl.ToString() + " "); //Console.Write("是否控制数据包的分段：" + pingReply.Options.DontFragment.ToString() + " "); //Console.Write("缓冲区大小：" + pingReply.Buffer.Length.ToString() + " "); Console.WriteLine(pingIP); } Console.WriteLine("------------------" + i.ToString()); } }
（二）异步操作
public static void SearchIPAnsyc() { try { for (int i = 1; i <= 255; i++) { Ping myPing = new Ping(); myPing.PingCompleted += new PingCompletedEventHandler(PingCompletedAction); string pingIP = "192.168.1." + i.ToString(); myPing.SendAsync(pingIP, 2000, null); Console.WriteLine("------------------" + i.ToString()); } } catch { } } private static void PingCompletedAction(object sender, PingCompletedEventArgs e) { List<string> ipList = new List<string>(); if (e.Reply.Status == IPStatus.Success) { ipList.Add(e.Reply.Address.ToString()); Console.Write(e.Reply.Address.ToString()); Console.WriteLine("Ansyc-----------------------"); } // Console.WriteLine("Ansyc-----------------------"); }
4）通过 SmtpClient类发送电子邮件
using System; using System.ComponentModel; using System.Net.Mail; using System.Text;
首相通过MailMessage添加邮件发送信息，包括主题，内容，附件等。其中附件通过Attachment类添加。
MailMessage类主题
string sendMail= "********@163.com"; string sendPwd = "*********"; MailAddress mailAddress = new MailAddress(sendMail); MailMessage mailMessage = new MailMessage(); mailMessage.To.Add("*******@qq.com");//添加发送地址，可添加多个 //mailMessage.CC.Add("00000@dd.com");//添加抄送地址 mailMessage.From = mailAddress; mailMessage.Subject = "test";//主题 mailMessage.SubjectEncoding = Encoding.UTF8; mailMessage.Body = "测试邮件";//正文 mailMessage.BodyEncoding = Encoding.Default;//正文的编码 mailMessage.Priority = MailPriority.High; mailMessage.IsBodyHtml = true; //添加附件 string[] attachments = new string[] { @"E:\C#\PingExec\NetHostSearch\bin\Debug\00.jpg" }; try { if(attachments.Length>0) { foreach(string attach in attachments) { Attachment attachment = new Attachment(attach); mailMessage.Attachments.Add(attachment); Console.WriteLine("Attach success"); } } } catch(Exception ex) { Console.WriteLine("Attach failed"+ex.Message); }
定义发送协议
//定义发送协议 SmtpClient smtpClient = new SmtpClient(); smtpClient.Credentials= new System.Net.NetworkCredential(sendMail, sendPwd); smtpClient.Host= "smtp.163.com";
smtpClient.Host对于不同的网址邮箱服务器不一样，比如扣扣邮箱则为"smtp.qq.com"
（一）同步发送
try { smtpClient.Send(mailMessage); Console.WriteLine("Success"); } catch (SmtpException ex) { Console.WriteLine("Failed：" + ex.Message); } mailMessage.Dispose();
（二）异步发送
//异步发送 也可以用SendMailAsync 其返回值为task，既可以调用task的continWith方法 smtpClient.SendCompleted += SendCompletedAction; smtpClient.SendAsync(mailMessage,null); Console.ReadKey();
异步发送 结束后调用SendCompletedAction，其定义如下
private static void SendCompletedAction(object sender, AsyncCompletedEventArgs e) { String token = (string)e.UserState; if (e.Cancelled) { Console.WriteLine("[{0}] Send canceled.", token); } if (e.Error != null) { Console.WriteLine("[{0}] {1}", token, e.Error.ToString()); } else { Console.WriteLine("Message sent."); } }
发送邮件为了便于理解在此进行了分步分割，一下为完整代码，其中同步发送方法已注释：
using System; using System.ComponentModel; using System.Net.Mail; using System.Text; namespace MailSendMgr { class Program { static void Main(string[] args) { string sendMail= "***********@163.com"; string sendPwd = "*************"; MailAddress mailAddress = new MailAddress(sendMail); MailMessage mailMessage = new MailMessage(); mailMessage.To.Add("************@qq.com");//添加发送地址，可添加多个 //mailMessage.CC.Add("00000@dd.com");//添加抄送地址 mailMessage.From = mailAddress; mailMessage.Subject = "test";//主题 mailMessage.SubjectEncoding = Encoding.UTF8; mailMessage.Body = "测试邮件";//正文 mailMessage.BodyEncoding = Encoding.Default;//正文的编码 mailMessage.Priority = MailPriority.High; mailMessage.IsBodyHtml = true; //添加附件 string[] attachments = new string[] { @"E:\C#\PingExec\NetHostSearch\bin\Debug\00.jpg" }; try { if(attachments.Length>0) { foreach(string attach in attachments) { Attachment attachment = new Attachment(attach); mailMessage.Attachments.Add(attachment); Console.WriteLine("Attach success"); } } } catch(Exception ex) { Console.WriteLine("Attach failed"+ex.Message); } //定义发送协议 SmtpClient smtpClient = new SmtpClient(); smtpClient.Credentials= new System.Net.NetworkCredential(sendMail, sendPwd); smtpClient.Host= "smtp.163.com"; //发送 //try //{ // smtpClient.Send(mailMessage); // Console.WriteLine("Success"); //} //catch (SmtpException ex) //{ // Console.WriteLine("Failed：" + ex.Message); //} //mailMessage.Dispose(); //异步发送 也可以用SendMailAsync 其返回值为task，既可以调用task的continWith方法 smtpClient.SendCompleted += SendCompletedAction; smtpClient.SendAsync(mailMessage,null); Console.ReadKey(); } private static void SendCompletedAction(object sender, AsyncCompletedEventArgs e) { String token = (string)e.UserState; if (e.Cancelled) { Console.WriteLine("[{0}] Send canceled.", token); } if (e.Error != null) { Console.WriteLine("[{0}] {1}", token, e.Error.ToString()); } else { Console.WriteLine("Message sent."); } } } }
