我们使用了这个技巧：
private static void TemporarilyHideLog4NetOnConsoleMessagesOnStartup()
{
var consoleOut = Console.Out;
var memoryStream = new MemoryStream();
var redirection = new StreamWriter(memoryStream );
Console.SetOut(redirection );
XmlConfigurator.Configure();
Console.SetOut(consoleOut );
}
这似乎有效，但似乎只是想知道是否有官方API。
