C#.net 调用OpenGL的glut函数总是死机？？？咋办？？

Question

本人想用C#.net调用OpenGL进行绘图，已经添加了using Tao.Platform.Windows;
using Tao.OpenGl;using Tao.FreeGlut;等引用，一般绘图没问题，但不能调用Glut函数，一旦调用，生成可以通过，但执行时总是执行不完，类似死机状态。请高手帮忙解决，非常感谢！！程序源代码如下：

Answer 1

你添加了glut.dll到你的系统目录了吗?

Answer 2

系统目录C:\WINDOWS\system32下既有glut32.dll，还有glut.dll，还有Tao.FreeGlut.dll啊！！

Answer 5

谢谢3楼的supper168！！！
不明白4楼什么意思？？？

Answer 6

不知道你用的lib是啥东西？共享下

Answer 7

c++中采用lib文件吧？？
我用的是c#，且OpenGL是Tao框架的OpenGL，没有lib文件，只有dll和xml文件。

Answer 8

没用过这个库，难道库有问题？？
找作者报个bug或是咨询下。

Answer 9

因为C#不象C++那样可以直接用OpenGL，所以只能借助一些辅助库。我在Google上搜了，国外也在用这个Tao框架。

Answer 10

楼主也是高手啊。我是菜菜鸟。学习学习。要是楼主弄一个C SHARP的游戏或是图形或是动画特效的教程就好了。

Answer 11

谢谢各位兄弟的帮忙！！还请各位高手指点！！
另外，13楼的你所说的“C SHARP的游戏或是图形或是动画特效的教程”，我没有，我只是有一些相关的源程序。

Answer 12

我也用C#做opengl，但用的是CsGL，这个连glut都没有，跟郁闷，现在感觉还是换Tao吧~~~

Answer 13

我也遇到你这个问题 用Tao.Opengl 和Tao.Platform.Windows 都没有问题 就是glut库有问题 郁闷死了 搞了几天了 

Answer 14

我用C++写的，同样是碰到死机的问题，是ChoosePixelFormat这个函数搞的，一跑到它就死了，我也不知道怎么解决，可能是驱动程序有问题，我跑到其他电脑上运行就没问题，一样的src，我再查查有没有解决办法。

Answer 15

“无法加载 DLL“freeglut.dll”: 找不到指定的模块。 (异常来自 HRESULT:0x8007007E)。”为何？有人知道吗？

Answer 16

重新在下载一个freeglut.dll文件,加载上
http://www.windows7recovery.com/post/2009/07/27/TaoFreeGlutdll-Download-File-TaoFreeGlutdll.aspx

Answer 17

把系统目录C:\WINDOWS\system32下的Tao.FreeGlut.dll换成 freeGlut.dll  我是这样解决的，呵呵
