log4net

问题 Is it possible to insert extra fields into the database and use them in log4net? I have a UserId I would like to have in an extra field in the log-table . I have added the field in the log4net.config : <parameter> <parameterName value="@userid" /> <dbType value="guid" /> <layout type="log4net.Layout.RawPropertyLayout" /> </parameter> But how do I update the ILog interface to support the extra database field. So I could for example log: log4net.LogManager.GetLogger("logname").Fatal(message,

问题 I have a WinForm that it display log information but I want it to display to only INFO level but I want the log in the log file to contain DEBUG level as well. Below is my configuration: <?xml version="1.0" encoding="utf-8" ?> <!-- This section contains the log4net configuration settings --> <log4net> <!-- Define some output appenders --> <appender name="LogFileAppender" type="log4net.Appender.RollingFileAppender"> <file value="${ALLUSERSPROFILE}\\Application Data\\logs\\Gateway" />

问题 Here's my web.config information: <configSections> <section name="log4net" type="log4net.Config.Log4NetConfigurationSectionHandler, log4net"/> </configSections> <log4net> <root> <level value="ALL" /> </root> <appender name="RollingFileAppender" type="log4net.Appender.RollingFileAppender"> <file value="c:\temp\log-file.txt" /> <appendToFile value="true" /> <rollingStyle value="Size" /> <maxSizeRollBackups value="10" /> <maximumFileSize value="1MB" /> <staticLogFileName value="true" /> <layout

问题 Is there a comprehensive list of all the conversion patterns available for log4net? I can't even find them in the source code. All I have found is this; shouldn't there be more patterns? For example, how would I get the name of the hosting application? Also, how can I add my own patterns? As an example here is the comparable list but for nlog. Edit: I have found the Pattern for application name; it's [Application] . But I'm still looking for the mother-load. Can someone at least point me to

问题 I'm trying to implement log4net 2.0.8 in our dot net core 1.1.2 app. The ConsoleAppender is working fine, but the AdoNetAppender throws an error: Could not load type 'log4net.Appender.AdoNetAppender' Is AdoNetAppender still not supported in Dot Net Core? My config: <?xml version="1.0" encoding="utf-8" ?> <log4net debug="true"> <appender name="ConsoleAppender" type="log4net.Appender.ConsoleAppender"> <layout type="log4net.Layout.PatternLayout"> <conversionPattern value="%date{ABSOLUTE} [

问题 I've bumped through a few of these questions laying around various sites and the answers seem to be spun by l4n officianados toward the value of the lightweight wrapper that log4net 'is' (don't you get it?) and similar points of mind-boggling fact. However it seems that what users are asking for (and this is my question) is how to fit the log4net objet model into the registertype/registerinstance sequence in the fluent config interface. The goal here wouldn't be to re-wrap l4n, but simply to

问题 When I run my application locally it writes my log4net log to the location I've configured (i.e., <file value="${LOCALAPPDATA}\TEST\Logs\debug.log" /> ) without a problem. However, when I deploy my application via ClickOnce, the log file is not being written. I know ClickOnce applications are limited in terms of where they can write to, but I was under the impression that LOCALAPPDATA (e.g., C:\Users\me\AppData\Local) was fair game. Any ideas? 回答1: Isolated Storage. 回答2: With ClickOnce, the

问题 When I use log4net for logging in .NET4.0 I use the following code LogManager declaration: private static readonly ILog log = LogManager.GetLogger(System.Reflection.MethodBase.GetCurrentMethod().DeclaringType); And when used in code: log.Info("My info text"); This outputs the following to the log-file: 2013-10-01 14:41:11,010 [3] INFO MyNamespace.MyClass [(null)] - My info text I am wondering what the [(null)] means and how I can remove/change it? This is my config-file: <?xml version="1.0"?>

问题 log4net 1.2.11.0 I am trying to get anything that will allow me to log with a unique value for each ASP.NET request. I tried %thread, but threads appear to be reused. I've tried %aspnet-request and %aspnet-session which don't have anything meaningful within them. I looked at ThreadContext.Properties and LogicalThreadContext.Properties but they don't have anything in them either. Anyone have a trick to get this done? I need the ability to pick a particular request's logs out of the log file.

问题 It seems cleaner to declare a logger and call LogManager.GetLogger in a base class so that everyone who is inheriting can use it. However, on log4net site and other blogs like in this blog post it states that it is better to declare one logger per class because: You can use loggers this way to isolate logging concerns across your objects, and I wholly recommend you do so. This will enable you to throttle and direct log output from individual loggers using log4net's hierarchical configuration
