NET实现注入代码的问题

时间：2011-03-19 来源：唯笑志在

最近想用NET实现注入代码，代码基本上没有什么问题，但是，被注入的DLL无法执行。但是用“DLL注入进程器.exe”测试是可以执行的，让我很郁闷。大家帮忙看看。

这是注入的代码：

public static bool Inject(int pid, string dllname)
{
try
{
int hProcess = -1,libFileRemote=-1;
hProcess = API.OpenProcess(API.PROCESS_ALL_ACCESS, false, pid);
if (hProcess <= 0)
return false;

int len=dllname.Length + 1;
libFileRemote = API.VirtualAllocEx(hProcess, 0,len , API.MEM_COMMIT, API.PAGE_READWRITE);

if(libFileRemote<=0)
return false;

int written = 0;
int result = API.WriteProcessMemory(hProcess, libFileRemote, dllname, len, ref written);
if (result <= 0)
return false;



int Kernel32=API.GetModuleHandle("kernel32");
if(Kernel32<=0)
return false;

int ThreadRtn = API.GetProcAddress(Kernel32,"LoadLibraryA");
if(ThreadRtn<=0)
return false;

int threadid=0;
int hRemoteThread = API.CreateRemoteThread(hProcess, 0, 0, ThreadRtn, libFileRemote, 0, ref threadid);

API.WaitForSingleObject(hRemoteThread, API.INFINITE);
API.CloseHandle(hRemoteThread);
API.VirtualFreeEx(hProcess, libFileRemote, 0, API.MEM_RELEASE);
return true;

}
catch (System.Exception ex)
{
throw ex;
}

}
