log4net write to a separate file

Is possible to write to a specific file when referencing a given appender?
Currently even if I reference to "RollingFile2" I am still writing to example.log file, instead of example2.log file
App.Config

How do I keep a log file per day in log4net? [duplicate]

This question already has answers here:
Having a log per day
(3 answers)
Closed 5 years ago.
I've inherited an application that I need to keep more than a single days of logs.
It is using log4net for it's logging, and I have the log4net.config file contents below:
<?xml version="1.0"?>
<log4net>
<appender name="Console" type="log4net.Appender.ConsoleAppender">
<layout type="log4net.Layout.PatternLayout">
<conversionPattern value="%date [%thread] %-5level %logger [%property{NDC}] - %message%newline" />
</layout>
</appender>
<appender name="RollingFileAppender" type="log4net.Appender.RollingFileAppender">
<file value="logs\connector.log" />
<appendToFile value="true" />
<rollingStyle value="Date" />
<datePattern value="yyyyMMdd" />
<maxSizeRollBackups value="10" />
<maximumFileSize value="5MB" />
<layout type="log4net.Layout.PatternLayout">
<conversionPattern value="%date [%thread] %-5level %logger [%property{NDC}] - %message%newline" />
</layout>
</appender>
<root>
<level value="INFO" />
<appender-ref ref="Console" />
<appender-ref ref="RollingFileAppender" />
</root>
</log4net>
The file in the log directory never has a date in it and is always called connector.log.
It's created date is from a long time ago, so I think it is simply emptying the file when it ticks over to a new day (and the timestamp of logs in that file prove that).
How would I change this so that it keeps a log file per day.

<appender name="SysAppender" type="log4net.Appender.RollingFileAppender,log4net">
<param name="File" value="App_Data/" />
<param name="AppendToFile" value="true" />
<param name="RollingStyle" value="Date" />
<param name="DatePattern" value=""Logs_"yyyyMMdd".htm"" />
<param name="StaticLogFileName" value="false" />

<!--<conversionPattern value="%newline %n记录时间：%date %newline %n 线程ID:[%thread] %n日志级别： %-5level %n跟踪描述：%message%newline %n"/>-->
</layout>

needn't define log file's name

c# log4net fillappend nothing happen

I need use log4net create a .txt and write log into .txt I did not konw what happen log4net not do anyting no create .txt and write log.
This is my log4net.config
<configuration>
<configSections>

this is Program.cs use log.info() and log.error
private static readonly log4net.ILoglog = log4net.LogManager.GetLogge(System.Reflection.MethodBase.GetCurrentMethod().DeclaringType);
static void Main(string[] args)
{
log.Info("log_info");
log.Error("log_error");
}
this is assemblyinfo.cs
[assembly: log4net.Config.XmlConfigurator(ConfigFile = "log4net.config", Watch = true)]

I found the problem, I have two .config one is App.config two is log4net.config if only write "log4net.config" ,it will not found the log4net.config.So need write the log4net.config path it will work.
[assembly: log4net.Config.XmlConfigurator(ConfigFile = #"C:\Users\username\Documents\Visual Studio 2015\Projects\Log\Log\log4net.config", Watch = true)]

log4net outputting file but not to debug window

I'm trying to get output from for errors to show up both in an appended logfile but also in the debug window. The logfile stuff is working correctly, but nothing every shows up in the debug window.
First, here is my config
<log4net>
<!--
This writes the log information to the console window. It only logs events
that are at least at the INFO level (which would mean that DEBUG events are not
captured.
-->
<appender name="ConsoleAppender" type="log4net.Appender.ConsoleAppender">
<layout type="log4net.Layout.PatternLayout">
<conversionPattern value="%date{ABSOLUTE} [%thread] %level %logger - %message%newlineExtra Info: %property{testProperty}%newline%exception"/>
</layout>
<filter type="log4net.Filter.LevelRangeFilter">
<levelMin value="DEBUG"/>
<levelMax value="FATAL"/>
</filter>
</appender>
<!--
This stores information in the logfile.txt file. It only captures log events
that contain the key word test or error.
-->
<appender name="RollingFileAppender" type="log4net.Appender.RollingFileAppender">
<file value="C:\TOPS\LOGFILES\logfile.txt"/>
<appendToFile value="true"/>
<rollingStyle value="Size"/>
<maxSizeRollBackups value="5"/>
<maximumFileSize value="10MB"/>
<staticLogFileName value="true"/>
<filter type="log4net.Filter.StringMatchFilter">
<stringToMatch value="test"/>
</filter>
<filter type="log4net.Filter.StringMatchFilter">
<stringToMatch value="error"/>
</filter>
<filter type="log4net.Filter.DenyAllFilter"/>
<layout type="log4net.Layout.PatternLayout">
<conversionPattern value="%date [%thread] %level %logger - %message%newline%exception"/>
</layout>
</appender>
<root>
<level value="DEBUG"/>
<appender-ref ref="ConsoleAppender"/>
<appender-ref ref="RollingFileAppender"/>
</root>
</log4net>
and then i call log4net in my code
log.Debug("Debug error logging", ex);
log.Info("Info error logging", ex);
log.Warn("Warn error logging", ex);
log.Error("Error error logging", ex);
log.Fatal("Fatal error logging", ex);
this creates 5 entries in my logfile, but no entries in my console window.
i have also modified my web.config so the appenders were as similar as possible, but i still get the exact same results
<log4net>

</appender>

</root>
</log4net>
any ideas on what i may have missed that is breaking the console output?
EDIT:
found the solution, as pointed out in the comments below by making3. i confused console appender and trace appender, which is what i was actually looking for. here's the updated config.

Set log level for Gallio execution log

How do I configure log4net or my Gallio test runners (Icarus and Echo) to use a different logging level for the Gallio Execution Log and my own file appender. I want my log file to have a DEBUG log level and Gallio to have an ERROR log level.
I thought this would work but Gallio is reading both appenders:
<log4net>
<appender name="Console" type="log4net.Appender.ConsoleAppender">
<layout type="log4net.Layout.PatternLayout">
<conversionPattern value="%5level [%thread] (%file:%line) - %message%newline" />
</layout>
</appender>
<appender name="File" type="log4net.Appender.FileAppender">
<file value="test.log" />
<appendToFile value="false" />
<lockingModel type="log4net.Appender.FileAppender+MinimalLock" />
<layout type="log4net.Layout.PatternLayout">
<conversionPattern value="%5level [%thread] (%file:%line) - %message%newline" />
</layout>
</appender>
<logger name="TestNamespace">
<level value="DEBUG" />
<appender-ref ref="File" />
</logger>
<root>
<level value="ERROR" />
<appender-ref ref="Console" />
</root>
</log4net>

Gallio is redirecting console output to its Execution Log. So I needed to set the threshold of the ConsoleAppender to the level I want for the Gallio Execution Log.
<log4net>
<appender name="Console" type="log4net.Appender.ConsoleAppender">
<threshold value="ERROR"/>
<layout type="log4net.Layout.PatternLayout">
<!-- Pattern to output the caller's file name and line number -->
<conversionPattern value="%5level [%thread] (%file:%line) - %message%newline" />
</layout>
</appender>
<appender name="File" type="log4net.Appender.FileAppender">
<threshold value="DEBUG"/>
<file value="test.log" />
<appendToFile value="false" />
<lockingModel type="log4net.Appender.FileAppender+MinimalLock" />
<layout type="log4net.Layout.PatternLayout">
<conversionPattern value="%5level [%thread] (%file:%line) - %message%newline" />
</layout>
</appender>
<root>
<appender-ref ref="Console" />
<appender-ref ref="File" />
</root>
</log4net>
