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?

调试器设置为


当前回答

在Visual Studio 2010中,我也会定期遇到这个问题。关闭Visual Studio,删除bin和obj目录,并重新启动将修复一个构建。然后问题又回来了。我已经尝试了这个帖子上的所有其他答案,但没有一个对我有效。对我来说,唯一能永久解决这个问题的方法就是打开项目设置,关闭“启用Visual Studio托管进程”,构建,再打开,然后再次构建。

将此添加到预构建:

(if exist "$(TargetDir)*old.exe" del "$(TargetDir)*old.exe") & (if exist "$(TargetDir)*.exe" ren "$(TargetDir)*.exe" *.old.exe)

.vhost.exe是一个调试器进程,因此正在调试的进程似乎没有正确关闭。有可能你有一个错误,使它仍然存在,并且没有正确地停止调试进程——当你单击“停止调试”而不是实际杀死调试器时,有一些选项可以从进程中分离出来,所以也许你有这样的设置。

但这就是问题所在——你试图复制的文件被操作系统锁定(即仍在使用),所以它阻止了复制。确保该文件是免费的,您将能够复制。

如果你使用Visual Studio Code (vsCode)遇到这个问题,或者你坚持使用终端命令,clean命令将删除构建文件,并通常修复描述的问题:

dotnet clean

然后,您可以返回运行:

dotnet build

or

dotnet run

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.

如果没有一个答案是正确的,试试这个简单的检查。 找到任何MSbuild.exe运行和持有您的项目EXE。杀死MSBuild.exe,你应该很好。
