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?

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)"

其他回答

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”)。

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"

似乎通过更改项目的程序集名称就可以解决这个问题。

所以不是这样

我把它变成这个

注意,我只是把它从Increment and Recall改成了Increment_Recall,我只是去掉了空格。它现在对我来说工作得很好。

您可以通过脚本终止应用程序。

如果你的应用程序名为myapp.exe,在终端中运行下一个脚本:

taskkill /IM myapp.exe /F

参数为:

/IM   application name (imagename)

 /F                     Specifies to forcefully terminate the process(es).

我意识到这只是为这个问题增加了一个已经非常多的答案,但我认为值得一提的是,尽管不完美,但@Stefano, @MichaelRibbons和@IvanFerrerVilla给出的答案的组合已经提供了一些不错的成功,因为他们各自都不太成功。
