这段代码提供了一个不错的接口来查找父流程对象，并考虑了多个具有相同名称的流程的可能性：
用法：
Console.WriteLine("ParentPid: " + Process.GetProcessById(6972).Parent().Id);码：
public static class ProcessExtensions { private static string FindIndexedProcessName(int pid) { var processName = Process.GetProcessById(pid).ProcessName; var processesByName = Process.GetProcessesByName(processName); string processIndexdName = null; for (var index = 0; index < processesByName.Length; index++) { processIndexdName = index == 0 ? processName : processName + "#" + index; var processId = new PerformanceCounter("Process", "ID Process", processIndexdName); if ((int) processId.NextValue() == pid) { return processIndexdName; } } return processIndexdName; } private static Process FindPidFromIndexedProcessName(string indexedProcessName) { var parentId = new PerformanceCounter("Process", "Creating Process ID", indexedProcessName); return Process.GetProcessById((int) parentId.NextValue()); } public static Process Parent(this Process process) { return FindPidFromIndexedProcessName(FindIndexedProcessName(process.Id)); }}
