C＃Opengl游戏cs 1.6截图（Opentk Library错误）

Question

我把这个问题放在opengl论坛上：

有一个人对我说，我没有拍摄游戏的截图，而且我已经创建了一个dll并注入游戏（反恐精英1.6）。

但是在执行framebuffer和grabscreenshot时我遇到了一些错误！

这是打印错误：

我正在注入这个来源：

void Inject()
    {
        System.IntPtr TargetProcessHandle;
        int TargetBufferSize;
        String pszLibFileRemote;
        int pfnStartAddr;
        Process[] TargetProcess = Process.GetProcessesByName("hl");
        TargetProcessHandle = OpenProcess(0x1F0FFF, false, TargetProcess[0].Id);
        pszLibFileRemote = Application.StartupPath + ("\\dll.dll");
        pfnStartAddr = GetProcAddress(GetModuleHandle("Kernel32.dll"), "LoadLibraryA");
        TargetBufferSize = 1 + pszLibFileRemote.Length;
        int Rtn;
        int LoadLibParamAdr;
        LoadLibParamAdr = VirtualAllocEx(TargetProcessHandle, 0, TargetBufferSize, 4096, 4);
        Rtn = WriteProcessMemory(TargetProcessHandle, LoadLibParamAdr, pszLibFileRemote, TargetBufferSize, 0);
        CreateRemoteThread(TargetProcessHandle, 0, 0, pfnStartAddr, LoadLibParamAdr, 0, 0);
        CloseHandle(TargetProcessHandle);
    } 

我在dll上编辑了一些代码：

Bitmap snapShotBmp = new Bitmap(width, height);
        System.Drawing.Imaging.BitmapData bmpData = snapShotBmp.LockBits(new Rectangle(0, 0, width, height), System.Drawing.Imaging.ImageLockMode.WriteOnly,
                                                  System.Drawing.Imaging.PixelFormat.Format24bppRgb);
        GL.ReadPixels(0, 0, width, height, OpenTK.Graphics.OpenGL.PixelFormat.Bgr, PixelType.UnsignedByte,
                      bmpData.Scan0);
        snapShotBmp.UnlockBits(bmpData);
        return snapShotBmp;

我正在用c＃语言编程！
