在C#中,Alert和日志記錄可以通過(guò)結(jié)合第三方庫(kù)或自定義實(shí)現(xiàn)來(lái)實(shí)現(xiàn)
首先,需要安裝NLog庫(kù)。在項(xiàng)目中使用NuGet包管理器安裝NLog:
Install-Package NLog
然后,創(chuàng)建一個(gè)NLog配置文件(例如:NLog.config):
<?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="file" xsi:type="File" fileName="logs/${shortdate}.log" />
</targets>
<rules>
<logger name="*" minlevel="Info" writeTo="file" />
</rules>
</nlog>
接下來(lái),在代碼中使用NLog記錄日志:
using NLog;
class Program
{
private static readonly Logger Logger = LogManager.GetCurrentClassLogger();
static void Main(string[] args)
{
Logger.Info("Application started");
// Your code here
Logger.Info("Application stopped");
}
}
public class Alert
{
public string Message { get; set; }
public AlertLevel Level { get; set; }
public enum AlertLevel
{
Info,
Warning,
Error,
Critical
}
}
public interface ILogger
{
void Log(Alert alert);
}
public class ConsoleAndNLogLogger : ILogger
{
private readonly Logger _nlog;
public ConsoleAndNLogLogger()
{
_nlog = LogManager.GetCurrentClassLogger();
}
public void Log(Alert alert)
{
Console.WriteLine($"[{alert.Level}] {alert.Message}");
switch (alert.Level)
{
case Alert.AlertLevel.Info:
_nlog.Info(alert.Message);
break;
case Alert.AlertLevel.Warning:
_nlog.Warn(alert.Message);
break;
case Alert.AlertLevel.Error:
_nlog.Error(alert.Message);
break;
case Alert.AlertLevel.Critical:
_nlog.Fatal(alert.Message);
break;
}
}
}
class Program
{
static void Main(string[] args)
{
ILogger logger = new ConsoleAndNLogLogger();
logger.Log(new Alert { Message = "Application started", Level = Alert.AlertLevel.Info });
// Your code here
logger.Log(new Alert { Message = "Application stopped", Level = Alert.AlertLevel.Info });
}
}
這樣,你就可以在代碼中使用自定義Alert和ILogger來(lái)記錄日志,并將日志輸出到控制臺(tái)和NLog。你可以根據(jù)需要擴(kuò)展Alert類(lèi)和ILogger接口以支持更多功能。
