我想在启动应用程序期间释放TCP端口(向用户确认),如何获取PID号,然后,如果用户确认,请将其删除?
我知道我可以通过netstat获取此信息,但是如何在脚本中或者在C#方法中更好。

您可以运行netstat,然后将输出重定向到文本流,以便您可以解析并获取所需的信息。
这就是我所做的。
netstat -a -n -o
作为流程运行linq
Process.Kill()
你必须进行异常处理。
namespace test
{
static class Program
{
/// <summary>
/// The main entry point for the application.
/// </summary>
static void Main()
{
Console.WriteLine("Port number you want to clear");
var input = Console.ReadLine();
//var port = int.Parse(input);
var prc = new ProcManager();
prc.KillByPort(7972);
}
}
public class PRC
{
public int PID { get; set; }
public int Port { get; set; }
public string Protocol { get; set; }
}
public class ProcManager
{
public void KillByPort(int port)
{
var processes = GetAllProcesses();
if (processes.Any(p => p.Port == port))
try{
Process.GetProcessById(processes.First(p => p.Port == port).PID).Kill();
}
catch(Exception ex)
{
Console.WriteLine(ex.Message);
}
else
{
Console.WriteLine("No process to kill!");
}
}
public List<PRC> GetAllProcesses()
{
var pStartInfo = new ProcessStartInfo();
pStartInfo.FileName = "netstat.exe";
pStartInfo.Arguments = "-a -n -o";
pStartInfo.WindowStyle = ProcessWindowStyle.Maximized;
pStartInfo.UseShellExecute = false;
pStartInfo.RedirectStandardInput = true;
pStartInfo.RedirectStandardOutput = true;
pStartInfo.RedirectStandardError = true;
var process = new Process()
{
StartInfo = pStartInfo
};
process.Start();
var soStream = process.StandardOutput;
var output = soStream.ReadToEnd();
if(process.ExitCode != 0)
throw new Exception("somethign broke");
var result = new List<PRC>();
var lines = Regex.Split(output, "\r\n");
foreach (var line in lines)
{
if(line.Trim().StartsWith("Proto"))
continue;
var parts = line.Split(new char[]{' '}, StringSplitOptions.RemoveEmptyEntries);
var len = parts.Length;
if(len > 2)
result.Add(new PRC
{
Protocol = parts[0],
Port = int.Parse(parts[1].Split(':').Last()),
PID = int.Parse(parts[len - 1])
});
}
return result;
}
}
}
