下面是我的配置和跟踪输出,它只是没有配置记录器,当我使用它时,没有任何内容写入日志(可能是因为没有启用所有日志级别).可能是什么问题呢？

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

<appSettings>
    <add key="log4net.Internal.Debug" value="true" />
</appSettings>

<log4net>
    <!-- Define some output appenders -->

    <appender name="RollingLogFileAppender" type="log4net.Appender.RollingFileAppender">
        <file value="logs\rolling-log.txt" />
        <appendToFile value="true" />
        <maxSizeRollBackups value="10" />
        <maximumFileSize value="100" />
        <rollingStyle value="Size" />
        <staticLogFileName value="true" />
        <layout type="log4net.Layout.PatternLayout">
            <header value="[Header]&#xD;&#xA;" />
            <footer value="[Footer]&#xD;&#xA;" />
            <conversionPattern value="%date [%thread] %-5level %logger [%ndc] - %message%newline" />
        </layout>
    </appender>

    <appender name="LogFileAppender" type="log4net.Appender.FileAppender">
        <file value="logs\bidz-log.txt" />
        <!-- Example using environment variables in params -->
        <!-- <file value="${TMP}\log-file.txt" /> --> …

如何使以下方法更具功能性 - linq-style？

    public static Dictionary<T, T> MergeDict<T, T>(Dictionary<T, T> a, Dictionary<T, T> b)
    {
        var e = new Dictionary<T, T>();

        a.Concat(b).ToList().ForEach(pair =>
        {
            e[pair.Key] = pair.Value;
        });

        return e;
    }
