Log4Net动态文件名不适用于GlobalContext[重复]

log4net file names based on GlobalContext properties

配置如下:

 <appender name="logger1" type="log4net.Appender.FileAppender">
    <file type="log4net.Util.PatternString" value="C:\temp\file_%property{foo}.log" />
    <appendToFile value="true" />         
    <Layout type="log4net.Layout.PatternLayout">
      <conversionPattern value="%newline%date --- %message%newline" />
    </Layout>    
 </appender>

以下是代码:

string foo= "bar";
log4net.GlobalContext.Properties["foo"] = foo;
_logger.ErrorFormat("test");
