How to get parent process in .NET in managed way

Question

I was looking a lot for method to get parent process in .NET, but found only P/Invoke way.

Answer 1

This way:

public static Process GetParent(this Process process)
{
  try
  {
    using (var query = new ManagementObjectSearcher(
      "SELECT * " +
      "FROM Win32_Process " +
      "WHERE ProcessId=" + process.Id))
    {
      return query
        .Get()
        .OfType()
        .Select(p => Process.GetProcessById((int)(uint)p["ParentProcessId"]))
        .FirstOrDefault();
    }
  }
  catch
  {
    return null;
  }
}
