Modes of archiving files based on time. Don't archive based on time. Archive every year. Archive every month. Archive daily. Archive every hour. Archive every minute. Writes log messages to one or more files. Documentation on NLog Wiki Initializes a new instance of the class. The default value of the layout is: ${longdate}|${level:uppercase=true}|${logger}|${message} Removes records of initialized files that have not been accessed in the last two days. Files are marked 'initialized' for the purpose of writing footers when the logging finishes. Removes records of initialized files that have not been accessed after the specified date. The cleanup threshold. Files are marked 'initialized' for the purpose of writing footers when the logging finishes. Flushes all pending file operations. The asynchronous continuation. The timeout parameter is ignored, because file APIs don't provide the needed functionality. Initializes file logging by creating data structures that enable efficient multi-file logging. Closes the file(s) opened for writing. Writes the specified logging event to a file specified in the FileName parameter. The logging event. Writes the specified array of logging events to a file specified in the FileName parameter. An array of objects.

Array of bytes that are ready to be written. Modifies the specified byte array before it gets sent to a file. The byte array. The modified byte array. The function can do the modification in-place. Gets or sets the name of the file to write to. This FileName string is a layout which may include instances of layout renderers. This lets you use a single target to write to multiple files. The following value makes NLog write logging events to files based on the log level in the directory where the application runs. ${basedir}/${level}.log All Debug messages will go to Debug.log, all Info messages will go to Info.log and so on. You can combine as many of the layout renderers as you want to produce an arbitrary log file name. Gets or sets a value indicating whether to create directories if they don't exist. Setting this to false may improve performance a bit, but you'll receive an error when attempting to write to a directory that's not present. Gets or sets a value indicating whether to delete old log file on startup. This option works only when the "FileName" parameter denotes a single file. Gets or sets a value indicating whether to replace file contents on each write instead of appending log message at the end.

Gets or sets a value indicating whether to enable log file(s) to be deleted. Gets or sets the file attributes (Windows only). Gets or sets the line ending mode. Gets or sets a value indicating whether to automatically flush the file buffers after each log message. Gets or sets the number of files to be kept open. Setting this to a higher value may improve performance in a situation where a single File target is writing to many files (such as splitting by level or by logger). The files are managed on a LRU (least recently used) basis, which flushes the files that have not been used for the longest period of time should the cache become full. As a rule of thumb, you shouldn't set this parameter to a very high value. A number like 10-15 shouldn't be exceeded, because you'd be keeping a large number of files open which consumes system resources. Gets or sets the maximum number of seconds that files are kept open. If this number is negative the files are not automatically closed after a period of inactivity. Gets or sets the log file buffer size in bytes. Gets or sets the file encoding. Gets or sets a value indicating whether concurrent writes to the log file by multiple processes on the same host. This makes multi-process logging possible. NLog uses a special technique that lets it keep the files open for writing. Gets or sets a value indicating whether concurrent writes to the log file by multiple processes on different network hosts. This effectively prevents files from being kept open. Gets or sets the number of times the write is appended on the file before NLog discards the log message. Gets or sets the delay in milliseconds to wait before attempting to write to the file again. The actual delay is a random value between 0 and the value specified in this parameter. On each failed attempt the delay base is doubled up to times. Assuming that ConcurrentWriteAttemptDelay is 10 the time to wait will be:

a random value between 0 and 10 milliseconds - 1st attempt
a random value between 0 and 20 milliseconds - 2nd attempt
a random value between 0 and 40 milliseconds - 3rd attempt
a random value between 0 and 80 milliseconds - 4th attempt
...

and so on.

Gets or sets the size in bytes above which log files will be automatically archived. Caution: Enabling this option can considerably slow down your file logging in multi-process scenarios. If only one process is going to be writing to the file, consider setting ConcurrentWrites to false for maximum performance.
Gets or sets a value indicating whether to automatically archive log files every time the specified time passes. Files are moved to the archive as part of the write operation if the current period of time changes. For example if the current hour changes from 10 to 11, the first write that will occur on or after 11:00 will trigger the archiving.

Caution: Enabling this option can considerably slow down your file logging in multi-process scenarios. If only one process is going to be writing to the file, consider setting ConcurrentWrites to false for maximum performance.

Gets or sets the name of the file to be used for an archive. It may contain a special placeholder {#####} that will be replaced with a sequence of numbers depending on the archiving strategy. The number of hash characters used determines the number of numerical digits to be used for numbering files. Gets or sets the maximum number of archive files that should be kept. Gets or sets the way file archives are numbered. Gets the characters that are appended after each line. Logs text to Windows.Forms.Control.Text property control of specified Name.

Asynchronous target wrapper allows the logger code to execute more quickly, by queueing messages and processing them in a separate thread. You should wrap targets that spend a non-trivial amount of time in their Write() method with asynchronous target to speed up logging.

Because asynchronous logging is quite a common scenario, NLog supports a shorthand notation for wrapping all targets with AsyncWrapper. Just add async="true" to the <targets/> element in the configuration file.

Documentation on NLog Wiki PostFilteringWrapper must be used with some type of buffering target or wrapper, such as AsyncTargetWrapper, BufferingWrapper or ASPNetBufferingWrapper.

This example works like this. If there are no Warn,Error or Fatal messages in the buffer only Info messages are written to the file, but if there are any warnings or errors, the output includes detailed trace (levels >= Debug). You can plug in a different type of buffering wrapper (such as ASPNetBufferingWrapper) to achieve different functionality.
