c# - MemoryAppender PatternLayout 不渲染？

Question

App.config 看起来像这样:

<appender name="MemoryAppender" type="log4net.Appender.MemoryAppender">
  <layout type="log4net.Layout.PatternLayout">
    <conversionPattern value="%date [%thread] %-5level - %message" />
  </layout>
</appender>

代码如下所示:

foreach (var ev in events)
{
   string msg = ev.RenderedMessage;
}

ev.RenderedMessage 返回的字符串只是消息，而不是整个模式。我还尝试将 WriteRenderedMessage 与 StringWriter 一起使用，结果是一样的。有没有办法通过应用的模式获取消息？

我找到了:)

var events = _ma.GetEvents();
string result = "";
using (StringWriter writer = new StringWriter())
{
    foreach (var ev in events)
    {
        _ma.Layout.Format(writer, ev);
        writer.Write(Environment.NewLine);
    }
    result = writer.ToString();
}
