在发布版本中使用TextWriter的奇怪行为 [英] Strange behavior using TextWriter in release version

问题描述

我有一个winforms应用程序，我正在阅读来自datareader的一些记录，并且

将它们写入一个类似的文件


SqlDataReader dataReader = sqlCommand.ExecuteReader（）;

TextWriter textWriter = new StreamWriter（strFileName）;

while（drReader.Read（））

{

strRecord = ////// strRecord在这里构建东西

textWriter.WriteLine（strRecord）;

iRecordCount ++;

}

textWriter.Close（）;


此代码在win XP上的调试模式和发布模式下工作正常但是失败
$ b win2000上的$ b发布模式。它没有失败，因为抛出任何异常或任何

错误并且似乎工作正常但没有创建文件。一切都显示

工作但我没有档案。


strFileName由多个变量组成，但最终看起来好像是
喜欢这个


c：\ XDataFiles \DataFiles\2006 \XData_06_21_2006.txt


如果不是使用strFileName，我硬代码它是


TextWriter textWriter = new

StreamWriter（@" c：\ XDataFiles \DataFiles\2006 \XData_ 06_21_2006.txt"） ;


它工作正常然后为我创建一个数据文件。


所以我很困惑为什么会这样。我没有在我的

win2000机器上安装IDE，所以我不能进入调试模式，它用于发布测试。

任何人都有任何想法？


谢谢

I have a winforms app that I''m reading some records from a datareader and
writing them out to a file like so

SqlDataReader dataReader = sqlCommand.ExecuteReader();
TextWriter textWriter = new StreamWriter(strFileName);
while(drReader.Read())
{
strRecord = ////// strRecord building stuff here
textWriter.WriteLine(strRecord);
iRecordCount++;
}
textWriter.Close();

This code works fine in debug mode and release mode on win XP but fails
release mode on win2000. It doesn''t fail as in throw any exceptions or any
errors and appears to work fine but no file is created. Everything appears
to work but I have no file.

strFileName is formed by a number of variables but ultimately looks
something like this

c:\XDataFiles\DataFiles\2006\XData_06_21_2006.txt

if instead of using strFileName, I hard code it to

TextWriter textWriter = new
StreamWriter(@"c:\XDataFiles\DataFiles\2006\XData_ 06_21_2006.txt");

it works fine then and creates a data file for me.

So I''m very confused as to why this is. I don''t have the IDE installed on my
win2000 machine so I can''t step into debug mode, its for release testing.
Anyone have any ideas?

Thanks

嗨D，


您可以做什么，作为临时调试是写入文件，控制台，

或显示包含字符串值的消息框

是''strFileName''。这可能是某种奇怪的条件支持

行导致strFileName无法正确形成。


此外，如果你''重新使用NTFS，检查目标

目录中的安全权限。


希望这会有所帮助，

Hi D,

What you can do, as a temporary debug is to write to a file, to the console,
or show messagebox containing the value of the string that
is ''strFileName''. It could be some sort of wierd condition back up the
line that''s causing strFileName not to be formed correctly.

Also, if you''re on NTFS, check your security permissions in the target
directory.

Hope this helps,

你好D，

你可以做什么，因为临时调试是写入文件，到
控制台，
或显示消息框，其中包含
为''strFileName''的字符串的值。可能是某些奇怪的条件支持
行导致strFileName无法正确形成。

另外，如果您在NTFS上，请检查您的安全权限在目标
目录中。

我不是将它视为一个安全问题，因为当我硬编码时，它的工作正常。

这个名字。加上我在管理员下运行它。我可以看到

文件名没有问题，我正在使用log4net记录器，看起来很完美

形成。


我我有一个想法，试图硬编码无意义的数据，我正在构建

strRecord（strRecord = // strRecord在这里构建东西''）


，我会硬编码一些无意义的数据，然后立即关闭以查看是否

在使用动态创建的strFileName时修复它。也许

while循环中的东西搞砸了。


谢谢。

I don''t see it as a security issue because it works fine when I hard code
the name in. Plus I''m running it under administrator . I can see the
filename no problem, I ''m using log4net logger and it seems perfectly
formed.

I''ve got an idea to try to hard code senseless data where I am building the
strRecord (strRecord = // strRecord building stuff here'' )

, I''ll hard code some senseless data then close immediately to see if that
fixes it while still using the dynamically created strFileName. Maybe
something in the while loop is messing things up.

Thanks.
