问题描述
Hi Coders！
我正在尝试在VSC＃2010中制作haar cascade的正面图像构建器（它的开发人员尚未在googlecode上更新）。经过几次解决后，我能够成功构建解决方案。但是当我点击F5时，它会抛出一个异常：
Hi Coders!
I'm trying to make "positive image builder for haar cascade" in VSC#2010(it has not been updated by its developer at googlecode). After going through few work-around I was able to successfully build solution. But when I hit F5, it throws an exception:
An unhandled exception of type 'System.AccessViolationException' occurred in OpenCvSharp.dll
Additional information: Attempted to read or write protected memory. This is often an indication that other memory is corrupt.
和绿色箭头指向行（在Form1.cs中）：

我不擅长编程以解决此内存访问问题。请帮忙。
pupil.avi出现在E：\HaarTraining\pupil.avi，所有其他文件也出现在App.config中的指定位置。
提前感谢您的帮助！
I'm not that good at programming to resolve this memory access.Please help.
pupil.avi is present at "E:\HaarTraining\pupil.avi" and all other file are also present at specified locations as in "App.config".
Thanks in advance for yoour help!
推荐答案
要完成OpenCV的安装，您可以必须重新启动Windows。
如果通过重新启动无法解决，请将以下文件从< OpenCV install
目录> / bin复制到您的VisualStudio项目目录（bin / Debug）。
cv110.dll
cxcore110.dll
cxts001.dll
ffopencv110.dll
highgui110.dll
ml110.dll
To complete the installation of OpenCV, you may have to restart Windows.
If not settled by restarting, copy the following files from <OpenCV install
directory>/bin to your VisualStudio project directory (bin/Debug).
cv110.dll
cxcore110.dll
cxts001.dll
ffopencv110.dll
highgui110.dll
ml110.dll
