在VS2012 c#项目的构建过程中，我一直得到这个错误
Error 41 Could not copy "obj\Debug\WeinGartner.WeinCad.exe" to
"bin\Debug\WeinGartner.WeinCad.exe".
Exceeded retry count of 10. Failed.
Error 42 Unable to copy file "obj\Debug\WeinGartner.WeinCad.exe" to
"bin\Debug\WeinGartner.WeinCad.exe". The process cannot access the file
'bin\Debug\WeinGartner.WeinCad.exe' because it is being used by another
process.
现在我知道该终止进程了
Weingartner.WeinCad.vhost.exe
(有时)有用，但这让我很紧张。有办法阻止这一切发生吗?

第一个消息错误解决方案:
在我的例子中，问题在于路径长度。
解决方案是减少/更改问题文件路径。如果问题出在项目中的文件上，你应该减少/更改存储库路径。
C:\Users\userTest\folder1\folder2\folder3\...\folderX\myProject\...\file.exe
如。
C:\Users\userTest\folder1\myProject\...\file.exe
换句话说，默认情况下路径长度不能超过260个字符。

遵循以下步骤
打开任务管理器(Ctrl + Alt + Delete) 在Performance选项卡下选择<ProjectNameOfYours.exe>。 单击End Process。 现在构建解决方案。
以上步骤永久地解决了错误。
对我来说，杀死vste .executionengine.exe进程(es)在90%的情况下解决了这个问题。如果这不起作用，那么也杀死QTAgent32.exe，然后删除项目的/bin和/obj文件夹。
这是我工作中最烦人的部分。：）
我能够修复这个问题(VS 2010)通过提供以下预构建操作;
if exist "$(TargetPath).locked" del "$(TargetPath).locked"
if exist "$(TargetPath)" if not exist "$(TargetPath).locked" move "$(TargetPath)" "$(TargetPath).locked"
I ran into this as well. It turns out that I had been testing with a service which I had built myself and which was running out the of the ..\bin\release directory of one of the projects in my solution. I had got the service running, but I forget to stop/uninstall it before returning to testing. As a result, it was holding on to one of the dlls that I reference and which needed to be moved (automatically as a dependency) from one project's bin/release subfolders to another. Stopping the service solved the problem.
Use
Debug.Flush();
Debug.Close();
如果发生异常，则在catch或finally中阻塞。
编辑: 我个人遇到过这个问题，我通常会做一个小技巧，效果很好。 我将构建类型从“调试”更改为“发布”(如果已经存在，则将“发布”更改为“调试”)。
