这是我的建议：
[Flags] public enum ThreadAccess : int { TERMINATE = (0x0001), SUSPEND_RESUME = (0x0002), GET_ConTEXT = (0x0008), SET_ConTEXT = (0x0010), SET_INFORMATION = (0x0020), QUERY_INFORMATION = (0x0040), SET_THREAD_TOKEN = (0x0080), IMPERSonATE = (0x0100), DIRECT_IMPERSonATION = (0x0200) } [Dllimport("kernel32.dll")] static extern IntPtr OpenThread(ThreadAccess dwDesiredAccess, bool bInheritHandle, uint dwThreadId); [Dllimport("kernel32.dll")] static extern uint SuspendThread(IntPtr hThread); [Dllimport("kernel32.dll")] static extern int ResumeThread(IntPtr hThread); [Dllimport("kernel32", CharSet = CharSet.Auto,SetLastError = true)] static extern bool CloseHandle(IntPtr handle);private static void SuspendProcess(int pid){ var process = Process.GetProcessById(pid); // throws exception if process does not exist foreach (ProcessThread pT in process.Threads) { IntPtr pOpenThread = OpenThread(ThreadAccess.SUSPEND_RESUME, false, (uint)pT.Id); if (pOpenThread == IntPtr.Zero) { continue; } SuspendThread(pOpenThread); CloseHandle(pOpenThread); }}public static void ResumeProcess(int pid){ var process = Process.GetProcessById(pid); if (process.ProcessName == string.Empty) return; foreach (ProcessThread pT in process.Threads) { IntPtr pOpenThread = OpenThread(ThreadAccess.SUSPEND_RESUME, false, (uint)pT.Id); if (pOpenThread == IntPtr.Zero) { continue; } var suspendCount = 0; do { suspendCount = ResumeThread(pOpenThread); } while (suspendCount > 0); CloseHandle(pOpenThread); }}
