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?

@Geoff (https://stackoverflow.com/a/25251766/3739540)的回答很好,但在重新编译时抛出错误代码1。

下面是对我有用的(2>nul 1>nul在结束+退出0):

(if exist "$(TargetDir)*old.pdb" del "$(TargetDir)*old.pdb") & (if exist "$(TargetDir)*.pdb" ren "$(TargetDir)*.pdb" *.old.pdb) 2>nul 1>nul
(if exist "$(TargetDir)*old.dll" del "$(TargetDir)*old.dll") & (if exist "$(TargetDir)*.dll" ren "$(TargetDir)*.dll" *.old.dll) 2>nul 1>nul
exit 0

在我的例子中,我在发布到它无法访问的文件夹时遇到了麻烦。您可以通过尝试发布到您的c驱动器中的一个文件夹来排除这种情况,您应该不会有访问问题。

我注意到一些答案可以解决我的问题,但是,以防有人有和我一样的问题。

如果你正在运行一个控制台应用程序:在你做任何其他事情之前。

确保您已经关闭了从以前的版本中打开的任何控制台窗口。例如,我只是在一个控制台应用程序中测试一些代码,我没有意识到以前运行程序时的控制台窗口是打开的。在我调试的过程中,窗口被推到后面,我看不到它。只是说,这可能是你的问题,所以检查确保这不是问题。

我发疯了,试图找到为什么系统进程在我正在工作的EXE上保持一个打开的句柄,在它被终止后的另一分钟,我得到了与OP相同的错误。

原因是之前的开发人员在使用(){}时没有包装IDisposable对象。一旦IDisposable对象正确地销毁自己,错误不再发生,我能够立即重建。

下面是一个脚本,绝对可以摆脱这个问题:

REM   This script is invoked before compiling an assembly, and if the target file exist, it moves it to a temporary location
REM   The file-move works even if the existing assembly file is currently locked-by/in-use-in any process.
REM   This way we can be sure that the compilation won't end up claiming the assembly cannot be erased!

echo PreBuildEvents 
echo  $(TargetPath) is %1
echo  $(TargetFileName) is %2 
echo  $(TargetDir) is %3   
echo  $(TargetName) is %4

set dir=C:\temp\LockedAssemblies

if not exist %dir% (mkdir %dir%)

REM   delete all assemblies moved not really locked by a process
del "%dir%\*" /q

REM   assembly file (.exe / .dll) - .pdb file and eventually .xml file (documentation) are concerned
REM   use %random% to let coexists several process that hold several versions of locked assemblies
if exist "%1"  move "%1" "%dir%\%2.locked.%random%"
if exist "%3%4.pdb" move "%3%4.pdb" "%dir%\%4.pdb.locked%random%"
if exist "%3%4.xml.locked" del "%dir%\%4.xml.locked%random%"

REM Code with Macros
REM   if exist "$(TargetPath)"  move "$(TargetPath)" "C:\temp\LockedAssemblies\$(TargetFileName).locked.%random%"
REM   if exist "$(TargetDir)$(TargetName).pdb" move "C:\temp\LockedAssemblies\$(TargetName).pdb" "$(TargetDir)$(TargetName).pdb.locked%random%"
REM   if exist "$(TargetDir)$(TargetName).xml.locked" del "C:\temp\LockedAssemblies\$(TargetName).xml.locked%random%"

REM PreBuildEvent code
REM   $(SolutionDir)\BuildProcess\PreBuildEvents.bat  "$(TargetPath)"  "$(TargetFileName)"  "$(TargetDir)"  "$(TargetName)"

脚本需要从每个VS项目预构建事件中调用。

$(SolutionDir)\BuildProcess\PreBuildEvents.bat  "$(TargetPath)"  "$(TargetFileName)"  "$(TargetDir)"  "$(TargetName)"

我以管理员的身份运行Visual Studio,设法解决了这个问题。
