问题 Closed. This question is off-topic. It is not currently accepting answers. Want to improve this question? Update the question so it's on-topic for Stack Overflow. Closed 9 months ago . Simple question: see title. I'm using .NET 3.5. Elaboration: I'm building a plugin that will be loaded into a 3rd party application at runtime. The main application uses log4net as its logging framework. However, it doesn't expose the root logger so we're unable to log. (I've raised this issue with the upstream

问题 I am using log4net for logging, I have two appenders one file and other eventlog appender. I have register application in registry editor, problem is now both logger are writing in event viewer. I need fileAppender to write in file and eventLogAppender to be shown in event viewer. <log4net> <appender name="LogFileAppender" type="log4net.Appender.FileAppender"> <file value="file.log"/> <appendToFile value="false"/> <layout type="log4net.Layout.PatternLayout"> <header value="Logging Start "/>

问题 I'm using the LogInfo() method to log to a rolling flat file, but I need to change the conversion pattern or pattern layout (whatever you want to call it) temporarily when calling it in a certain circumstance. Is this possible? 回答1: Yes it is, for instance like this: var appenders = log4net.LogManager.GetRepository().GetAppenders(); foreach (var rollingFileAppender in appenders.OfType<log4net.Appender.RollingFileAppender>()) { rollingFileAppender.Layout = new log4net.Layout.PatternLayout("-

问题 I inherited some code that uses the priority element under the root in its xml configuraiton. This is just like the example at http://iserialized.com/log4net-for-noobs/ which shows: <root> <priority value="ALL" /> <appender-ref ref="LogFileAppender" /> <appender-ref ref="ConsoleAppender"/> </root> However, the log4net configuration examples at http://logging.apache.org/log4net/release/manual/configuration.html always show it using the level element: <root> <level value="DEBUG" /> <appender

问题 I'm looking at a fresh asp.net site in 3.5 that has absolutely no error handling or logging. What are some good options for logging and handling errors? I've used Log4Net on the 1.1 framework but hear there are potentially better options in 3.5. 回答1: One option is ELMAH. I asked a question about it here: ASP.NET Error Handling. Since then, I have implemented a slightly modified version of it and the logging plus e-mail is great and easy to integrate via the web.config file. 回答2: We use two

问题 I've checked the connection string (I got it from the server explorer). I've checked the commandText in log4net config. I've checked the database permissions (integrated security is fine and works outside of the log4net class). I've checked the repository's configured property (it is configured, it finds the config file fine). I've also checked that the fields defined in the config file match the attributes (field size etc.) of the table in the database. Any ideas? When I'm debugging it seems

问题 Should I be using the ILog or ILogger interface? I find the ILog interface to be easier to use since I can just declare one instance per class by calling: private ILog _logger = LogManager.GetLogger(typeof(MyClass)); It's a much simpler interface then the ILogger: void Log(Type callerStackBoundaryDeclaringType, Level level, object message, Exception exception) Is there a difference? When is it better to use 1 vs the other? 回答1: I recommend the ILog interface. This has been pushed by Apache

问题 I've set up a logfileAppender and a consoleAppender in my log4net config for my application. I would like the logfile appender to only write ERROR messages and above and the console appender to write DEBUG and above. My config is: <log4net debug="false"> <appender name="LogFileAppender" type="log4net.Appender.FileAppender,log4net" > <param name="File" value="log.txt" /> <param name="AppendToFile" value="true" /> <layout type="log4net.Layout.PatternLayout,log4net"> <param name=

问题 In my app.config I put <appender name="RollingFileAppender" type="log4net.Appender.RollingFileAppender"> <file value="%programdata%/log-file.txt"/> but it didn't work. Any ideas? 回答1: The log4net syntax for expanding environment variables is "${Variable}" e.g. <file value="${LOCALAPPDATA}\GojiSoft\GojiLog\log.txt" /> 回答2: Resurrecting an old thread here, but I encountered the same issue and thought I'd share. ${PROGRAMDATA}, as discussed in the comment thread of the other answer, didn't work
