问题 Is it possible to make a filter, for example a PropertyFilter that is neutral (and passed to next filter in the chain) if either one or another value matches? Something like: <filter type="log4net.Filter.PropertyFilter"> <Key value="myProperty" /> <StringsToMatch Operator="OR"> <Match>value1</Match> <Match>value2</Match> </StringsToMatch> </filter> I really don't want to write my own filter and would prefer to accomplish this with the normal Log4Net filters. Is this possible? 回答1: You could

问题 I want to be able to specify multiple smtp server host addresses and implement a logic whereby if email using one smtp server fails, it tries to send using the next smtp server address. Is it possible using log4net. Can we override some functions of log4net and implement our own logic in it to send emails? <appender name="SmtpAppender" type="log4net.Appender.SmtpAppender"> <to value="group@ivp.in" /> <from value="uname@ivp.in" /> <subject>Error Notification</subject> **<smtpHost value="10.0.0

问题 I have implement a custom log4net appender by extending the AppenderSkeleton-class. It was as simple as anyone could ask for and works perfectly. My problem is that I had to hardcode a few values and I'd like to remove them from my code to the configuration of the appender. Since log4net knows how it is configured I think there should be a way to ask log4net for it's configuraion. My appender could look something like this: <appender name="MyLogAppender" type="xxx.yyy.zzz.MyLogAppender">

问题 We have a couple of long lived objects each of the same class in the system. There are only about 5 or 6 and they are connections to outside systems. I want each of those instances to have their own file that they can log to. What is the best way to do this? I can only see adding loggers programatically as the answer right now. UPDATE: I want to avoid using the configuration file because if I add a new connection to a different remote host then i want its log output to go to file named after

问题 This question already has answers here : How to log stack trace using log4net (C#) (5 answers) Closed 5 years ago . I would like to use ErrorFormat method because it is easer to read, safer and faster. But I also want to log the exception stacktrace. I tried log.ErrorFormat("My {0} message", "pretty", exception); But it only logs "My pretty message" Is it possible to use Error/Debug/Info Format in such way? Thanks. 回答1: How about: log.ErrorFormat("My {0} message: {1}", "pretty", exception);

问题 I was happily using log4net with my WPF program on an XP machine and happily using a fileAppender FileAppender to write log messages to c:\log.txt. All was well. However, it does not work on a Windows 7 machine. No error or anything, just that the file isn't created, much less logged to. A little research reveals that it's a file permissions problem (UAC) with Windows 7, and in fact it works if I run the executable as administrator. It doesn't work if I just click on it (even though I'm

问题 I'm making a vehicle tracking application(ASP.NET MVC C#). I have windows service that takes data sent by GPS device. In the service I have written the code to Log the data. Now consider a normal logging scenario in which i have only one GPS device. 08:00:24 Inside OnDataAvailable Method 08:00:25 Data Received - Device Id: 2 Data: abcdefghijkl 08:00:25 Leaving OnDataAvailable and few more statements. and then it repeats Now when I have more than one GPS device sending data, the log gets mixed

问题 I wrote a log4net wrapper public class Log4NetWrapper : ILogger { private readonly log4net.ILog logger; public Log4NetWrapper(string loggerName) { logger = log4net.LogManager.GetLogger(loggerName); } public void Debug(string message, params object[] values) { logger.DebugFormat(message, values); } public bool IsDebugEnabled {get { return logger.IsDebugEnabled; } } ... } the problem is that the line and file I get when logging is of the wrapper and not the actual location of the message. 回答1:

问题 Is it possible to configure log4net to roll files each hour? If not - any hints on how to override RollingFileAppender with required functionality to make HourlyRollingFileAppender? 回答1: Yes: set the datePattern element's value to "yyyyMMdd-HH" <appender name="RollingLogFileAppender" type="log4net.Appender.RollingFileAppender"> <file value="logfile" /> <appendToFile value="true" /> <rollingStyle value="Date" /> <datePattern value="yyyyMMdd-HH" /> <layout type="log4net.Layout.PatternLayout">
