等待进程启动 C#

Question

嘿伙计们，我似乎无法让我的代码按我想要的方式工作。我正在等待一个进程开始，也就是出现在我的任务管理器中。虽然找不到该过程，但我一直在循环；如果找到进程，则中断 while 循环并执行以下 AKA 注入 DLL 的逻辑。我有断点，但我的代码一直在循环，所以它就像从未找到进程一样，尽管它显示在任务管理器中。

public static int inject(string dllPath, Process tProcess)
{
  Process targetProcess = tProcess;
  string dllName = dllPath;
  const string PROCESSNAME = "BatteryLife.exe";
  // Length == 0 = False?
   while (Process.GetProcessesByName(PROCESSNAME).Length == 0)
   {
     var test3 = "";
     Thread.Sleep(100);
     // Length == 1 = True?
     if (Process.GetProcessesByName(PROCESSNAME).Length == 1)
      break;
     var test = "";
   }
   var test2 = "";
   // the target process
   // geting the handle of the process - with required privileges
   IntPtr procHandle = OpenProcess(PROCESS_CREATE_THREAD |   PROCESS_QUERY_INFORMATION | PROCESS_VM_OPERATION | PROCESS_VM_WRITE | PROCESS_VM_READ, false, targetProcess.Id);
  // searching for the address of LoadLibraryA and storing it in a pointer
  IntPtr loadLibraryAddr = GetProcAddress(GetModuleHandle("kernel32.dll"), "LoadLibraryA");
  // name of the dll we want to inject
  // alocating some memory on the target process - enough to store the name of the dll
  // and storing its address in a pointer
  IntPtr allocMemAddress = VirtualAllocEx(procHandle, IntPtr.Zero, (uint)((dllName.Length + 1) * Marshal.SizeOf(typeof(char))), MEM_COMMIT | MEM_RESERVE, PAGE_READWRITE);
  // writing the name of the dll there
  UIntPtr bytesWritten;
  WriteProcessMemory(procHandle, allocMemAddress,    Encoding.Default.GetBytes(dllName), (uint)((dllName.Length + 1) *  Marshal.SizeOf(typeof(char))), out bytesWritten);
 // creating a thread that will call LoadLibraryA with allocMemAddress as argument
  CreateRemoteThread(procHandle, IntPtr.Zero, 0, loadLibraryAddr, allocMemAddress, 0, IntPtr.Zero);
  return 0;
}

我认为您需要从进程名称 string 中删除 .exe。

Process[] pname = Process.GetProcessesByName("BatteryLife");
if (pname.Length == 0)
{
  .....
}
