Using Autofac to inject log4net into controller

由 倖福魔咒の 提交于 2020-01-12 05:24:09
问题 Trying to use Autofac to inject a log4net class into my controller, but I get the following exception: None of the constructors found with 'Public binding flags' on type 'MvcApplication6.Controllers.HomeController' can be invoked with the available services and parameters: Cannot resolve parameter 'log4net.ILog logger' of constructor 'Void .ctor(log4net.ILog)'. I have created a module to inject the Log class using the correct type: public class LogInjectionModule : Module { protected override

Using other log4net logging levels than the usual ones

由 老子叫甜甜 提交于 2020-01-12 05:12:06
问题 I've realised that there is more levels than all, debug, info, warn, error and fatal, they are listed in the log4net.Core.Level class. But how can I use them? I mean, in the ILog interface you have methods to use the usual ones, but what if you want to use "Fine" or "Emergency", etc? Cheers. 回答1: In the following example Log is of type ILog . Log.Logger.Log(null, log4net.Core.Level.Emergency, "Help!", null); For each level you check their Value in order to know when they are disabled. For

log4net - FileAppender writing new entries at the beginning of file

由 别说谁变了你拦得住时间么 提交于 2020-01-11 08:40:31
问题 Is is possible to configure FileAppender in log4net to add new entries at the beginning of log file? Currently it is adding entries at the end and reading newest entries requires scrolling whole log down. It would be more comfortable to read from the beginning. 回答1: I don't know if that option is available in log4net (I wouldn't think so), but even if it's available I would advice against using it. Appending to a file is a quite cheap operation. The bytes are just added to the end of the file

Change name of logfile a few times during runtime

问题 Is it possible to change the name of a logfile for a fileappender while the application is running? It will be done a few times / day. I'll try to elaborate myself a bit more: my app writes firmware on a device. All the devices the user already worked on, are in a grid. The user can start a new writing-wizard or can resume or restart the action on an already started device. What I would like to do is keep a log of all the steps performed by the user for a certain device. For example: when the

问题 Please help. I have a web application that was built in VS2010 and we are using the CR plugin for 2010 and everything works perfect on our local machines. When we go to deploy the web application to Server 2008 the application runs fine until we try to get to a report. When we get to a report we receive...

Log4Net: Programmatically specify multiple loggers (with multiple file appenders)

由 独自空忆成欢 提交于 2020-01-08 12:27:21
问题 How to (programmatically, without xml config) configure multiple loggers with Log4Net? I need them to write to different files. 回答1: This thread at the log4net Dashboard details an approach. To summarize a little, hopefully without ripping off too much code: using log4net; using log4net.Appender; using log4net.Layout; using log4net.Repository.Hierarchy; // Set the level for a named logger public static void SetLevel(string loggerName, string levelName) { ILog log = LogManager.GetLogger

Create a ReadOnly log file with Log4Net AND Separate log in 2 files

由 主宰稳场 提交于 2020-01-07 07:45:24
问题 The first question is: I'm developing application in c# that creates 2 log files (.txt files): one for errors and another for modifications made by users. This two files are created with log4net . The issue I see is that these files can be edited, and so altered by mistake. I would like to set these files to readonly, and that log4net still could write to them. Because if I just change the property in the file, the next log won't be written. Is there a way to do that? Also, the user of the

Log4net: How to enable debug logging at runtime?

由 こ雲淡風輕ζ 提交于 2020-01-07 02:51:10
问题 In the test environment, the debug log is enabled, so I can see detailed debug log messages. In production environment, I want to disable debug log by default, but still want to enable/disable it if needed. Can I enable debug log at runtime without restarting my application? My logging code looks like below: if(logger.IsDebugEnabled) Logger.Debug("debug message"); 回答1: You can change to loglevel by setting it and then apply the new settings: ((log4net.Repository.Hierarchy.Hierarchy)LogManager
