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

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”)。

看看另一个答案。基本上,你可以让MSBuild.exe进程在后台运行,消耗资源文件。如果你有任何构建前或构建后的任务,导致MSBuild通过命令行启动,尝试添加"/nr:false"标志到这个命令。但是,关于更具体的细节,请参见前面的回答。

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)"

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。

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。

我不能给出一个解决方案来防止这种情况发生,但你至少可以重命名锁定文件(windows资源管理器,或经典命令窗口),然后编译/构建。不需要重启VS201x。如果有一些经验,你可以添加一个预构建脚本来删除旧文件或重命名,以防出现锁。
