Java 如何关闭C中的所有子进程#

C#代码：

我正在从C#windows应用程序调用java.exe。java.exe用于测试某些网站。Java使用Selenium通过打开默认web浏览器来测试网页。它将打开3到10次浏览器并测试测试用例。我想在C#应用程序中添加停止按钮，当我们单击它时，它应该关闭java.exe以及那些打开的浏览器。怎么做

我试图通过使用像这样的exe名称来获取进程名称

ProcessStartInfo processStartInfo = new ProcessStartInfo();
processStartInfo.Verb = "runas";        
processStartInfo.FileName = fileNameToExecute;
processStartInfo.Arguments = parameters;
Process process = new Process();
processStartInfo.UseShellExecute = false;
processStartInfo.CreateNoWindow = true;
processStartInfo.RedirectStandardOutput = true;
processStartInfo.RedirectStandardError = true;
process.StartInfo = processStartInfo;
process.Start();
process.WaitForExit();
process.Close();

但它不起作用。

找到

java.exe

进程的进程ID，然后启动

TASKKILL

，将

/T

参数作为外部进程，以杀死整个父进程和子进程树：

例如：

Process[] processName = Process.GetProcessesByName(fileName.Substring(0, fileName.LastIndexOf('.')));

在启动新进程之前，我已将processId存储在全局变量中

Process process = new Process();
processStartInfo.UseShellExecute = false;
processStartInfo.CreateNoWindow = true;
processStartInfo.RedirectStandardOutput = true;
processStartInfo.RedirectStandardError = true;

process.StartInfo = processStartInfo;
process.Start();
javaExeProcessId = process.Id; //global variable
process.WaitForExit();
process.Close();

我称之为KillProcessAndChildren（javaexecprocessid）；在需要时终止当前进程及其子进程

Process process = new Process();
processStartInfo.UseShellExecute = false;
processStartInfo.CreateNoWindow = true;
processStartInfo.RedirectStandardOutput = true;
processStartInfo.RedirectStandardError = true;

process.StartInfo = processStartInfo;
process.Start();
javaExeProcessId = process.Id; //global variable
process.WaitForExit();
process.Close();

private static void KillProcessAndChildren(int pid)
{
    // Cannot close 'system idle process'.
    if (pid == 0)
    {
        return;
    }
    ManagementObjectSearcher searcher = new ManagementObjectSearcher
            ("Select * From Win32_Process Where ParentProcessID=" + pid);
    ManagementObjectCollection moc = searcher.Get();
    foreach (ManagementObject mo in moc)
    {
        KillProcessAndChildren(Convert.ToInt32(mo["ProcessID"]));
    }
    try
    {
        Process proc = Process.GetProcessById(pid);
        proc.Kill();
    }
    catch (Exception ex)
    {
        // Process already exited.
    }
}
