【问题描述】:
我正在尝试通过添加一个包装 log4net 的独立项目来启用解决方案范围的日志记录。我在 StackOverflow 上找到了一个代码,但该代码使用了一些配置文件。我不明白那一点。这是唯一的静态类:
using log4net;
using log4net.Config;
using System;
using System.IO;
namespace ExciteEngine2.LoggingManager {
//// TODO: Implement the additional GetLogger method signatures and log4net.LogManager methods that are not seen below.
public static class ExciteLog {
private static readonly string LOG_CONFIG_FILE = @"log4net.config";
public static ILog GetLogger(Type type) {
// If no loggers have been created, load our own.
if (LogManager.GetCurrentLoggers().Length == 0) {
LoadConfig();
}
return LogManager.GetLogger(type);
}
private static void LoadConfig() {
//// TODO: Do exception handling for File access issues and supply sane defaults if it's unavailable.
try {
XmlConfigurator.ConfigureAndWatch(new FileInfo(LOG_CONFIG_FILE));
}
catch (Exception ex) {
}
}
}
}
现在,任何地方都没有 log4net.config。在我的主要应用程序项目中,我使用 ILog 如下:
using log4net;
using ExciteEngine2.LoggingManager;
namespace ExciteEngine2.MainApplication {
internal static class Program {
public static readonly ILog ApplicationLogger = ExciteLog.GetLogger(typeof(Program));
private static void SetupLogging() {
log4net.Config.XmlConfigurator.Configure();
}
[STAThread] static void Main(string[] args) {
//Uninstall
foreach (string arg in args) {
if (arg.Split('=')[0] == "/u") {
Process.Start(new ProcessStartInfo(Environment.GetFolderPath(Environment.SpecialFolder.System) + "\\msiexec.exe", "/x " + arg.Split('=')[1]));
return;
}
}
Thread.CurrentThread.CurrentCulture = new CultureInfo("en-GB");
Thread.CurrentThread.CurrentUICulture = new CultureInfo("en-GB");
Application.EnableVisualStyles();
Application.SetCompatibleTextRenderingDefault(false);
Application.ThreadException += new ThreadExceptionEventHandler(Application_ThreadException);
try {
ThemeResolutionService.ApplicationThemeName = ConfigurationManager.AppSettings["ThemeToUse"];
}
catch (Exception ex) {
ApplicationLogger.Error("Exception while setting Telerik Theme.", ex);
ThemeResolutionService.ApplicationThemeName = "ControlDefault";
}
DevExpress.UserSkins.OfficeSkins.Register();
DevExpress.UserSkins.BonusSkins.Register();
DevExpress.Skins.SkinManager.EnableFormSkins();
DevExpress.Skins.SkinManager.EnableMdiFormSkins();
//try {
if (args.Contains("/dx")) {
Application.Run(new AppMDIRibbonDX());
ApplicationLogger.Info("Application (DX) started.");
}
else {
Application.Run(new AppMDIRibbon());
ApplicationLogger.Info("Application started.");
}
//} catch (Exception ex) {
// ApplicationLogger.Fatal("Exception while initiating. Nothing can be done here.", ex);
// XtraMessageBox.Show(String.Format("Exception while initiating. Nothing can be done here.{0}Message: {1}", Environment.NewLine, ex.Message), "Excite Engine 2", MessageBoxButtons.OK, MessageBoxIcon.Error);
//}
}
private static void Application_ThreadException(object sender, ThreadExceptionEventArgs e) {
ApplicationLogger.Fatal("Application Level Exception.", e.Exception);
Thread t = (Thread)sender;
Exception threadexception = e.Exception;
string errormessage = String.Format("Thread ID: {0} [ {1} ]", t.ManagedThreadId, threadexception.Message);
XtraMessageBox.Show(String.Format("Application Level Exception!{1}{0}{1}Details:{1}{2}", errormessage, Environment.NewLine, threadexception.StackTrace), "Excite Engine 2", MessageBoxButtons.OK, MessageBoxIcon.Error);
}
}
}
从我的流程中可以看出,我正在执行这行代码,认为 log4net 将使用我的主应用程序项目的 app.config:log4net.Config.XmlConfigurator.Configure();
这是我在 AssemblyInfo.cs 中添加的一行:
[assembly: log4net.Config.XmlConfigurator(Watch = true)]
最后,我的主应用程序的 app.config:
<?xml version="1.0"?>
<configuration>
<configSections>
<section name="log4net" type="log4net.Config.Log4NetConfigurationSectionHandler,Log4net"/>
</configSections>
<appSettings>
</appSettings>
<connectionStrings>
</connectionStrings>
<startup>
<supportedRuntime version="v4.0" sku=".NETFramework,Version=v4.0" />
</startup>
<log4net>
<root>
<level value="DEBUG" />
<appender-ref ref="LogFileAppender" />
</root>
<appender name="LogFileAppender" type="log4net.Appender.RollingFileAppender" >
<param name="File" value="Excite Engine 2 Log.log" />
<param name="AppendToFile" value="true" />
<rollingStyle value="Size" />
<maxSizeRollBackups value="10" />
<maximumFileSize value="10MB" />
<staticLogFileName value="true" />
<layout type="log4net.Layout.PatternLayout">
<param name="ConversionPattern" value="%-5p%d{ddd, dd-MMM-yyyy hh:mm:ss} - %m%n" />
</layout>
</appender>
<appender name="EventLogAppender" type="log4net.Appender.EventLogAppender" >
<applicationName value="Excite Engine 2" />
<layout type="log4net.Layout.PatternLayout">
<conversionPattern value="%date [%thread] %-5level %logger [%property{NDC}] - %message%newline" />
</layout>
</appender>
</log4net>
</configuration>
当我使用<appender-ref ref="LogFileAppender" /> 运行时,我在主EXE 旁边得到一个名为Excite Engine 2 Log.log 的空文件。当我设置<appender-ref ref="EventLogAppender" /> 时,事件查看器中没有任何反应。此外,还有一个属性:<level value="DEBUG" /> 这真的很困扰我。我想要的是为我的应用程序提供完整的 EventViewer 日志记录,而不管它运行的构建配置如何。
感谢有人可以指导我。谢谢!
【问题讨论】:
-
level value="DEBUG" 与您的构建配置无关,这意味着它将在 DEBUG 及更高级别(DEBUG、INFO、WARN、ERROR、FATAL)进行日志记录。
