英文:
NLog: replace \r\n with actual line break in file
问题
How to make NLog insert actual line breaks to the target file instead of \r\n in ${message}?
如何使NLog在目标文件中插入实际的换行符而不是${message}中的\r\n？
英文:
How to make NLog insert actual line breaks to the target file instead of \r\n in ${message}?
I am using a config file to configure NLog as follows:
<?xml version="1.0" encoding="utf-8" ?><nlog xmlns="http://www.nlog-project.org/schemas/NLog.xsd"xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"><variable name="logDirectory" value="Logs" /><targets><target name="txtFile" xsi:type="File" fileName="${logDirectory}/${shortdate}.txt" /><target name="jsonFile" xsi:type="File" fileName="${logDirectory}/${shortdate}.json" ><layout type="JsonLayout" IndentJson="true"><attribute name="time" layout="${date:format=yyyy-MM-dd HH\:mm\:ss}" /><attribute name="message" layout="${message:raw=true}" /><attribute name="exception" layout="${exception}" /></layout></target></targets><rules><logger name="*" minlevel="Error" writeTo="jsonFile" /></rules></nlog>
and I am using NLog in a C# application. The logged messages contain Environment.NewLine characters which are currently replaced by \r\n in the log file.
public class SomeClass{static readonly Logger logger = LogManager.GetCurrentClassLogger();public void DoStuff(){try{// ... some code}catch(Exception n){string msg = "Failed to do stuff" + Environment.NewLine +"Try again later";logger.Error(n, msg);}}}

使用NLog的JsonLayout时，它会将换行符编码为字符\r\n，这是JSON格式所需的。
如果不需要正确的JSON输出，那么可以使用选项encode="false"：
<layout xsi:type="JsonLayout" IndentJson="true"><attribute name="message" layout="${message:raw=true}" encode="false" /></layout>
或者，可以考虑停止使用JsonLayout。
英文:
When using the NLog JsonLayout, then it will encode newlines as the chars \r\n, as required by the JSON-format.
If correct JSON output is not relevant, then you can use the option encode="false":
<layout xsi:type="JsonLayout" IndentJson="true"><attribute name="message" layout="${message:raw=true}" encode="false" /></layout>
Alternative stop using JsonLayout.
