Log file not created?

Question

I am using log4net and have completely setup it up with param name="File" value= "C:\Application.log". Yet the file is not created in C:. I am running Windows 7 and maybe something like permissions is preventing the file from being created.
Here is the app.config:
<?xml version="1.0" encoding="utf-8" ?>
<configuration>
<configSections>
<section name="log4net" type="log4net.Config.Log4NetConfigurationSectionHandler,Log4net" />
</configSections>

<log4net>
<root>
<level value="DEBUG" />
<appender-ref ref="LogFileAppender" />
</root>
<appender name="LogFileAppender“ type=“log4net.Appender.RollingFileAppender" >
<param name="File" value="C:\Users\Mohit\Documents\Application.log" />
<param name="AppendToFile" value="true" />
<rollingStyle value="Size" />
<maxSizeRollBackups value="10" />
<maximumFileSize value="10MB" />
<staticLogFileName value="true" />
<layout type="log4net.Layout.PatternLayout">
<param name="ConversionPattern“ value=“%-5p%d{yyyy-MM-dd hh:mm:ss} – %m%n" />
</layout>
</appender>
</log4net>
</configuration>

Answer 1

Yeah, make sure the user that is executing the application has write permissions to c:.

Better yet, you probably don't want to write your application log to the root c:\ directory. It would probably be better to choose a location where your app is installed, or somewhere under Documents and Settings (or the Windows 7 equivalent).

Answer 2

You must provide a real file name. What you defined within your config is a folder name. Instead of:

<param name="File" value="C:\Users\Mohit\Documents" />

use something like:

<param name="File" value="C:\Users\Mohit\Documents\log.txt" />

Also, you'll probably need elevated permissions for your application to write the log to the root c: folder. UAC won't let you write to root folder.

Like Andy said, you'll be better to choose some subfolder of Windows Users folder like:

c:\Users\Mohit\AppData\Local\<MyApplication>

log4net has some predefined variables you can use to target special folders. There are some questions about that here on SO:
