应用程序不记录

我有许多使用log4net的ASP.NET应用程序没有问题。我无法使用log4net来记录我使用MVC库编写的任何服务中的任何内容。我在所有服务中都具有相同的配置（除了日志文件名）。每个服务都作为同一个用户运行，并使用相同的应用程序池。

以下是我使用的配置：

<log4net>
        <appender name="XMLAppender" type="log4net.Appender.RollingFileAppender">
            <file value="C:\logs\SERVICENAME.Log.xml"/>
            <appendToFile value="true"/>
            <rollingStyle value="Composite"/>
            <datePattern value="yyyyMM"/>
            <maxSizeRollBackups value="10"/>
            <maximumFileSize value="100MB"/>
            <layout type="log4net.Layout.XmlLayoutSchemaLog4j">
                <locationInfo value="false"/>
            </layout>
    </appender>
        <root>
            <level value="INFO"/>
            <appender-ref ref="XMLAppender"/>
        </root>
    </log4net>

我总共有configSection条目，如下所示：

<configSections>
    <section name="log4net" type="log4net.Config.Log4NetConfigurationSectionHandler, log4net"/>
...
</configSections>

我还打开了log4net调试并设置system.diagnostics将跟踪写入文件。在这里我看到了MVC和非MVC应用程序之间输出的差异。

MVC：

log4net DefaultRepositorySelector: repository [log4net-default-repository] already exists, using repository type [log4net.Repository.Hierarchy.Hierarchy]

在这两种情况下，我都按如下方式创建ILog对象：

private static readonly ILog log = LogManager.GetLogger（typeof（CLASSNAME））;

我是否缺少某些东西或需要做些什么改变才能让它适用于MVC？此时，如果已知可以正常使用MVC，我也愿意更改为另一个日志记录解决方案。

我知道这篇文章已经很老了，但我也在WCF项目中遇到了这个问题（默认的log4net存储库）。 我使用带有log4net部分的web.config（不是单独的log4net.config文件）。

为了解决这个问题，我在AssemblyInfo.cs中放置了以下内容：

[assembly: log4net.Config.XmlConfigurator(ConfigFile = "Web.config", Watch = true)]

如果使用外部配置文件也是如此。 HTH， 夏兰

我的Web应用程序是一个ASP.NET MVC，在Web根目录中有一个单独的log4net.config文件。

经过大量的谷歌搜索和拔毛后，我通过 Application_Start （在Global.asax中）中的代码初始化log4net：

protected void Application_Start()
{
    var logConfigFilePath = Server.MapPath("~/log4net.config");

    log4net.Config.XmlConfigurator.ConfigureAndWatch(new System.IO.FileInfo(logConfigFilePath));
}

这解决了我的问题，log4net开始正确记录。

使用NLog。似乎工作。我必须将NLog.config文件放在基本目录中（与web.config一起），它运行正常。能够写入正确的目录，这证明了目录权限设置正确。大约需要5分钟才能完成更改。

很高兴知道为什么log4net拒绝播放。

就我而言，这是因为项目属性设置为输出到bin \ debug，但log4net dll要求log4net.config文件存在于BIN文件夹中。我将项目属性更改为输出到bin文件夹，然后将log4net.config文件在构建时复制到正确的位置。

此外，确保为log4net配置文件设置“copy local”也可以防止出现许多问题。
