Salvete! nLog for .NET具有将日志条目作为电子邮件发送的功能。但是,如果我们想要发送整个当前日志文件,那么如何将日志文件读入字符串并将其作为nLog {$message}
传递呢?我没有看到nLog在其mailtarget
附件中有一个属性用于附件。怎么办呢?

我今天刚刚用C#做过这个。我按照arkmuetz提供的答案How to get path of current target file using NLog in runtime?来首先获取Nlog目标的文件名。然后我读取文件并将文件的内容复制到另一个Nlog目标,该目标通过电子邮件发送邮件正文中的日志。
首先我创建了一个NlogHelper类
public static class NlogHelper
{
/// <summary>
/// Gets LogFileName by TargetName
/// </summary>
/// <param name="targetName">The nLog targetname for the specified logger.</param>
/// <returns></returns>
/// <remarks>https://stackoverflow.com/questions/11452645/how-to-get-path-of-current-target-file-using-nlog-in-runtime</remarks>
public static string GetLogFileName(string targetName)
{
string fileName = null;
if (LogManager.Configuration != null && LogManager.Configuration.ConfiguredNamedTargets.Count != 0)
{
Target target = LogManager.Configuration.FindTargetByName(targetName);
if (target == null)
{
throw new Exception("Could not find target named: " + targetName);
}
FileTarget fileTarget = null;
WrapperTargetBase wrapperTarget = target as WrapperTargetBase;
// Unwrap the target if necessary.
if (wrapperTarget == null)
{
fileTarget = target as FileTarget;
}
else
{
fileTarget = wrapperTarget.WrappedTarget as FileTarget;
}
if (fileTarget == null)
{
throw new Exception("Could not get a FileTarget from " + target.GetType());
}
var logEventInfo = new LogEventInfo { TimeStamp = DateTime.Now };
fileName = fileTarget.FileName.Render(logEventInfo);
}
else
{
throw new Exception("LogManager contains no Configuration or there are no named targets");
}
//if (!File.Exists(fileName))
//{
// throw new Exception("File " + fileName + " does not exist");
//}
return fileName;
}
}
接下来,我在构造函数中检索了文件名并将其存储起来供以后使用。
_logLileName = NlogHelper.GetLogFileName("DailyFile");
出于我的目的,我创建了一个属性,后来我用它来检索日志文件的内容。
public string LogFileContent
{
get
{
return File.ReadAllText(_logLileName);
}
}
最后,我将文件的内容添加到要通过电子邮件发送的日志中。
_logger.Error("Excel Builder LinkShare Error encountered -- Some companies did not complete succesfully!. Please review logs. \n" + mfb.LogFileContent);
这是我的nLog.config文件,它有助于使事情变得更加清晰。
<?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" >
<targets>
<target name="console" xsi:type="ColoredConsole"
layout="${date:format=HH\:mm\:ss}|${level}|${stacktrace}|${message}" />
<target name="file" xsi:type="File" fileName="${basedir}/DomoExcelBuilderLog.txt"
layout="${stacktrace} ${message}" />
<target name="DailyFile" xsi:type="File" fileName="C:\Temp\Log${shortdate}.txt"
layout="${date:format=HH\:mm\:ss} --> ${message}" deleteOldFileOnStartup="true" />
<target name="file2" xsi:type="File" fileName="${basedir}/ServiceLog.txt"
layout="${stacktrace} ${message}" />
<target name="MyMailer" xsi:type="Mail"
smtpServer="some.server.com"
smtpPort="587"
smtpAuthentication="Basic"
smtpUsername="no-reply"
smtpPassword="somepassword"
enableSsl="true"
from="no-reply@some.server.com"
to="myemail@gmail.com"/>
</targets>
<rules>
<logger name="MultipleFileBuilder" minlevel="Trace" writeTo="DailyFile" />
<logger name="ExcelBuilderService" minlevel="Debug" writeto="MyMailer" />
</rules>
</nlog>
我的应用程序首先登录名为“MultipleFileBuilder”的记录器。然后我使用NLogHelper类来检索Target'DailiyFile'的内容。
希望这有助于某人。
(注意:我删除了检查以查看文件是否存在于'GetLogFileName'方法中,因为在我的情况下文件不存在。)

我认为您可以使用目标组合:默认目标+ MethodCall,然后手动发送电子邮件或使用Mail + Buffering发送一批记录。
