从 C# 应用程序执行 netstat 返回“找不到文件”错误

Question

我正在尝试从我的 C# 代码执行 netstat 命令并得到“找不到文件”错误。 我必须指定“netstat.exe”在哪里吗？

如果是这样，如果（假设）netstat 和 findstr 位于两个不同的文件夹中，我该怎么做？

    Process cmd = new Process();
    cmd.StartInfo.FileName = "netstat -a | findstr 5840";
    cmd.StartInfo.RedirectStandardInput = true;
    cmd.StartInfo.RedirectStandardOutput = true;
    cmd.StartInfo.CreateNoWindow = true;
    cmd.StartInfo.UseShellExecute = false;

    try
    {
        cmd.Start();
    }
    catch (System.ComponentModel.Win32Exception ex)
    {
        Console.WriteLine(ex.Message);
    }
    cmd.StandardInput.Flush();
    cmd.StandardInput.Close();
    cmd.WaitForExit();
    StreamReader reader = cmd.StandardOutput;
    string output = reader.ReadToEnd();
    Console.WriteLine(output);

这就是解决问题的方法：

// create the ProcessStartInfo using "cmd" as the program to be run and "/c " as the parameters.
// /c tells cmd that we want it to execute the command that follows and then exit.
string command = "netstat -a | findstr " + sTCPPort;
ProcessStartInfo procStartInfo =  new ProcessStartInfo("cmd", "/c " + command);

// The following commands are needed to redirect the standard output.
// This means that it will be redirected to the Process.StandardOutput StreamReader.
procStartInfo.RedirectStandardOutput = true;
procStartInfo.UseShellExecute = false;
// Do not create the black window.
procStartInfo.CreateNoWindow = true;
// Now we create a process, assign its ProcessStartInfo and start it
Process proc = new Process();
proc.StartInfo = procStartInfo;
proc.Start();
// Get the output into a string
result = proc.StandardOutput.ReadToEnd();

如果没有看到确切的信息，很难知道确切的问题，但看起来您可能需要 cmd.exe 并将您的命令作为参数传递给它。
