一个基于C#编写的基础网络信息检测工具

这个程序设计了五个模块，如下：
1.获取本地主机的主机名、ipv4地址、ipv6地址
2.获取远程主机的ip地址、延迟等
3.获取网络适配器信息（网卡信息），包含名称、mac地址等
4.获取网络流量信息，包含ipv4的统计信息：所在域、接收数据包、发送数据包、丢弃数据包等
5.调用cmd执行网络状态重置命令：netsh winsock reset

获取本地主机信息代码如下：

this.richTextBox1.Clear();
//获取主机名，回环string localHostName = Dns.GetHostName();IPAddress loopbackip = IPAddress.Loopback;
richTextBox1.AppendText(" 主机名：" localHostName "
");richTextBox1.AppendText(" 回环地址：" loopbackip);//获取本机ipv4IPHostEntry localhost = Dns.GetHostEntry(localHostName);IPAddress[] iPAddressesList = Dns.GetHostAddresses(localHostName);
//输出ipv6foreach (IPAddress ipa in iPAddressesList){ if (ipa.AddressFamily == System.Net.Sockets.AddressFamily.InterNetworkV6) { richTextBox1.AppendText("
 IPv6：" ipa); }}
//输出ipv4foreach (IPAddress ipa in iPAddressesList){ if (ipa.AddressFamily == System.Net.Sockets.AddressFamily.InterNetwork) { richTextBox1.AppendText("
 IPv4地址：" ipa); }}richTextBox1.AppendText("
 可分配端口最小值：" IPEndPoint.MinPort);richTextBox1.AppendText("
 可分配端口最大值：" IPEndPoint.MaxPort "
");GetNetworkFlow();

获取远程主机信息代码如下：

this.richTextBox2.Clear();
IPHostEntry remotaHost = Dns.GetHostEntry(this.textBox1.Text);IPAddress[] remotaIP = remotaHost.AddressList;foreach (IPAddress ipa in remotaIP){ if(ipa.AddressFamily == System.Net.Sockets.AddressFamily.InterNetwork) { richTextBox2.AppendText(" 目标主机地址：" ipa "
"); }}string hostAddress = this.textBox1.Text.Trim();Ping pingSender = new Ping();PingOptions options = new PingOptions();options.DontFragment = true;string testData = "Test Data";byte[] buffer = Encoding.ASCII.GetBytes(testData);int timeout = 120;
//调用同步的Send方法发送数据，将结果保存至PingReply实例PingReply reply = pingSender.Send(hostAddress, timeout, buffer, options);if (reply.Status == IPStatus.Success){ richTextBox2.AppendText(" 往返时间：" reply.RoundtripTime "
"); richTextBox2.AppendText(" 生存时间：" reply.Options.Ttl "
"); richTextBox2.AppendText(" 是否控制数据包的分段：" reply.Options.DontFragment "
"); richTextBox2.AppendText(" 缓冲区大小：" reply.Buffer.Length "
");}

获取网络适配器信息代码如下：

NetworkInterface[] AdapterInfoBox = NetworkInterface.GetAllNetworkInterfaces();
for (int i = 0; i < AdapterInfoBox.Length; i ) { richTextBox3.AppendText(" ------------------------------------第" (i 1) "个网络适配器信息------------------------------------
"); richTextBox3.AppendText(" 描述信息：" AdapterInfoBox.Description "
"); richTextBox3.AppendText(" 名称：" AdapterInfoBox.Name "
"); richTextBox3.AppendText(" 类型：" AdapterInfoBox.NetworkInterfaceType "
"); richTextBox3.AppendText(" 速度：" AdapterInfoBox.Speed / 1000 / 1000 "
"); richTextBox3.AppendText(" MAC地址：" BitConverter.ToString(AdapterInfoBox.GetPhysicalAddress().GetAddressBytes()) "
");}

获取网络流量代码如下：

//获取包含本机的网络连接和通信统计数据的信息的对象IPGlobalProperties NetworkInfo = IPGlobalProperties.GetIPGlobalProperties();//获取本机IPv4统计数据IPGlobalStatistics NetworkFlow = NetworkInfo.GetIPv4GlobalStatistics();
richTextBox1.AppendText("
 网络流量统计：
");richTextBox1.AppendText(" 本机所在域 ······ " NetworkInfo.DomainName "
");richTextBox1.AppendText(" 接收数据包 ······ " NetworkFlow.ReceivedPackets "
");richTextBox1.AppendText(" 传送数据包 ······ " NetworkFlow.ReceivedPacketsDelivered "
");richTextBox1.AppendText(" 转发数据包 ······ " NetworkFlow.ReceivedPacketsForwarded "
");richTextBox1.AppendText(" 丢弃数据包 ······ " NetworkFlow.ReceivedPacketsDiscarded "
");

调用cmd执行命令的代码如下：

string reset = "netsh winsock reset";string restart = "shutdown -r -t 0";//创建实例Process p = new Process();//设置要启动的应用程序p.StartInfo.FileName = "cmd.exe";//是否使用操作系统shell启动p.StartInfo.UseShellExecute = false;// 接受来自调用程序的输入信息p.StartInfo.RedirectStandardInput = true;//输出信息p.StartInfo.RedirectStandardOutput = true;// 输出错误p.StartInfo.RedirectStandardError = true;//不显示程序窗口p.StartInfo.CreateNoWindow = true;//启动程序p.Start();
//向cmd窗口发送输入信息p.StandardInput.WriteLine(reset "&" restart "&exit");p.StandardInput.AutoFlush = true;
this.Close();
