log4net 文件名重叠解决办法

此为多线程写日志造成

解决办法，在appender节点里添加：

<param name="lockingModel"  type="log4net.Appender.FileAppender+MinimalLock" />

完整XML示例：

<log4net>
    <root>
      <level value="ALL" />
      <appender-ref ref="RollingLogFileAppender" />
    </root>
    <appender name="RollingLogFileAppender" type="log4net.Appender.RollingFileAppender">
      <lockingModel type="log4net.Appender.FileAppender+MinimalLock" />
      <param name="File" value="Log/" />
      <param name="AppendToFile" value="true" />
      <param name="MaxSizeRollBackups" value="10" />
      <param name="StaticLogFileName" value="false" />
      <param name="DatePattern" value="yyyy-MM-dd&quot;.log&quot;" />
      <param name="RollingStyle" value="Date" />
      <layout type="log4net.Layout.PatternLayout">
        <param name="Header" value="----------------------------------------[Header]--------------------------------------&#xA;&#xA;" />
        <param name="Footer" value="----------------------------------------[Footer]--------------------------------------&#xA;&#xA;" />
        <param name="ConversionPattern" value="%d [%t] %-5p %c [%x] - %m%n%n" />
      </layout>
    </appender>
  </log4net>
