log4net将不会在Windows 7上创建日志文件 [英] log4net will not create logfile on Windows 7

问题描述

我有一个使用log4net进行日志记录的程序集。

我在Assemblynfo.cs文件中有这个：

  [assembly：log4net.Config.XmlConfigurator（ConfigFile =log4net.config，Watch = true）] 
  

log4net.config文件如下所示：

 <？xml version =1.0encoding =utf-8？> 
< log4net> 
< appender name =ConsoleAppendertype =log4net.Appender.ConsoleAppender> 
< layout type =log4net.Layout.PatternLayout> 
<！ - < conversionPattern value =％date [％thread]％-5级别％logger [％ndc]  - ％message％newline/> - > 
< conversionPattern value =％ -  5p％d％5rms％-22.22c {1}％-18.18M  - ％m％n/> 
< / layout> 
< / appender> 
 
< appender name =RollingLogFileAppendertype =log4net.Appender.RollingFileAppender> 
< file value =$ {APPDATA} \\DC Lasersystem\\DCMark\\DCMarkLog.txt/> 
< appendToFile value =true/> 
< rollingStyle value =Date/> 
< datePattern value =yyyy-MM-dd/> 
< maxSizeRollBackups value =10/> 
< layout type =log4net.Layout.PatternLayout> 
< conversionPattern value =％ -  5p％d％5rms％-22.22c {1}％-18.18M  - ％m％n/> 
< / layout> 
< / appender> 
 
< appender name =TraceAppendertype =log4net.Appender.TraceAppender> 
< layout type =log4net.Layout.PatternLayout> 
< conversionPattern value =％ -  5p％d％5rms％-22.22c {1}％-18.18M  - ％m％n/> 
< / layout> 
< / appender> 
 
< appender name =EventLogAppendertype =log4net.Appender.EventLogAppender> 
< layout type =log4net.Layout.PatternLayout> 
<！ - < conversionPattern value =％date [％thread]％-5级别％logger [％ndc]  - ％message％newline/> - > 
< conversionPattern value =％ -  5p％d％5rms％-22.22c {1}％-18.18M  - ％m％n/> 
< / layout> 
< / appender> 
 
< root> 
< level value =DEBUG/> 
< appender-ref ref =RollingLogFileAppender/> 
< / root> 
< / log4net> 
  

当我从IDE运行我的应用程序时，它工作。 DCMarkLog.txt文件在％APPDATA％\DC Lasersystem\DCMark 目录中创建。

我安装应用程序并从Program Files目录运行它，然后我没有得到一个日志文件！

我在安装目录中有与Release目录中相同的文件。

我猜这是一种不正确的权限...

有一个线索？

解决方案

权限问题。在Windows 7中，您需要管理员权限才能写入 Program Files 目录。您必须：

• 以管理员身份运行您的应用程序






要查找正确的写入位置，请参阅：

I have an assembly that uses log4net for logging.
I have this in the Assemblynfo.cs file:

[assembly: log4net.Config.XmlConfigurator(ConfigFile = "log4net.config", Watch = true)]

The log4net.config file looks like this:

<?xml version="1.0" encoding="utf-8" ?>
<log4net>
  <appender name="ConsoleAppender" type="log4net.Appender.ConsoleAppender" >
    <layout type="log4net.Layout.PatternLayout">
      <!--          <conversionPattern value="%date [%thread] %-5level %logger [%ndc] - %message%newline" /> -->
      <conversionPattern value="%-5p %d %5rms %-22.22c{1} %-18.18M - %m%n" />
    </layout>
  </appender>

  <appender name="RollingLogFileAppender" type="log4net.Appender.RollingFileAppender">
    <file value="${APPDATA}\\DC Lasersystem\\DCMark\\DCMarkLog.txt" />
    <appendToFile value="true" />
    <rollingStyle value="Date" />
    <datePattern value=" yyyy-MM-dd" />
    <maxSizeRollBackups value="10" />
    <layout type="log4net.Layout.PatternLayout">
      <conversionPattern value="%-5p %d %5rms %-22.22c{1} %-18.18M - %m%n" />
    </layout>
  </appender>

  <appender name="TraceAppender" type="log4net.Appender.TraceAppender">
    <layout type="log4net.Layout.PatternLayout">
      <conversionPattern value="%-5p %d %5rms %-22.22c{1} %-18.18M - %m%n" />
    </layout>
  </appender>

  <appender name="EventLogAppender" type="log4net.Appender.EventLogAppender" >
    <layout type="log4net.Layout.PatternLayout">
      <!--          <conversionPattern value="%date [%thread] %-5level %logger [%ndc] - %message%newline" /> -->
      <conversionPattern value="%-5p %d %5rms %-22.22c{1} %-18.18M - %m%n" />
    </layout>
  </appender>

  <root>
    <level value="DEBUG" />
    <appender-ref ref="RollingLogFileAppender" />
  </root>
</log4net>

When I run my application from the IDE it works. The DCMarkLog.txt file is created in %APPDATA%\DC Lasersystem\DCMark directory.

BUT When I install the application and run it from Program Files directory then I don't get a log file!

I have the same files in the install directory as in the Release directory.

I'm guessing it's some kind of permission that isn't right...

Anyone that has a clue?

解决方案

This is a permission issue. In Windows 7 you require administrator rights to write to the Program Files directory. You will have to either:

• Run your application as Administrator
• Or the preferred way write your log file to a folder where user has write access to.

To find the correct location to write to refer to: Where to store Application Data in Windows 7 and Vista
