xBIM使用Log4Net来记录异常不适合的处理错误和警告。它在xBIM几何引擎中被大量使用来记录所有几何错误。如果您的文件看起来不太正确,则应始终先检查日志。Log4Net有许多可能的配置,包括记录到控制台,创建连续或滚动日志文件等。这里可以找到一些例子。在控制台中编写所有彩色日志消息的最基本配置可能如下所示:
1 <?xml version="1.0" encoding="utf-8" ?> 2 <configuration> 3 <configSections> 4 <section name="log4net" type="log4net.Config.Log4NetConfigurationSectionHandler, log4net" /> 5 </configSections> 6 <log4net> 7 <!-- 定义默认日志操作 --> 8 <root> 9 <appender-ref ref="console" /> 10 <!-- 设置日志等级 ALL DEBUG INFO WARN ERROR FATAL NONE --> 11 <level value="ALL" /> 12 </root> 13 <appender name="console" type="log4net.Appender.ColoredConsoleAppender"> 14 <mapping> 15 <level value="FATAL" /> 16 <foreColor value="White" /> 17 <backColor value="Red" /> 18 </mapping> 19 <mapping> 20 <level value="ERROR" /> 21 <foreColor value="Red, HighIntensity" /> 22 </mapping> 23 <mapping> 24 <level value="WARN" /> 25 <foreColor value="Green, HighIntensity" /> 26 </mapping> 27 <mapping> 28 <level value="INFO" /> 29 <foreColor value="Blue, HighIntensity" /> 30 </mapping> 31 <mapping> 32 <level value="DEBUG" /> 33 <foreColor value="White" /> 34 </mapping> 35 <layout type="log4net.Layout.PatternLayout"> 36 <conversionPattern value="%-5level - %message [%logger %type.%method Line %line]%newline" /> 37 </layout> 38 </appender> 39 </log4net> 40 <startup> 41 <supportedRuntime version="v4.0" sku=".NETFramework,Version=v4.5.2" /> 42 </startup> 43 </configuration>
您还可以使用xBIM基础结构来记录您自己的消息,如下所示:
1 using Xbim.Common.Logging; 2 3 4 var log = LoggerFactory.GetLogger(); 5 6 log.Info("Examples are just about to start."); 7 log.Warn("Always use LINQ instead of general iterations!"); 8 log.Error("This is how the error would be logged with log4net."); 9 log.Info("All examples finished.");
