網上找了一個操作powershell的com+組件源碼，配置好后，發現啟用郵箱不穩定。因此在代碼中用log4net加入異常日志記錄。如下：

private static readonly ILog log = LogManager.GetLogger("ErrorLog");public bool IsExistMailBox(string identity){try{PSSnapInException PSException = null;RunspaceConfiguration runspaceConf = RunspaceConfiguration.Create();runspaceConf.AddPSSnapIn("Microsoft.Exchange.Management.PowerShell.Admin", out PSException);Runspace runspace = RunspaceFactory.CreateRunspace(runspaceConf);runspace.Open();Pipeline pipeline = runspace.CreatePipeline();string errors = string.Empty;using (pipeline){Command command = new Command("Get-Mailbox");command.Parameters.Add("identity", identity);//command.Parameters.Add("DomainController", "XX"); pipeline.Commands.Add(command);Collection<PSObject> result = pipeline.Invoke();if ((pipeline.Error != null) && (pipeline.Error.Count > 0)){foreach (object obj2 in pipeline.Error.ReadToEnd()){errors = errors + obj2.ToString() + "|";}//記錄log信息log.Info(identity + "PipeLine[Get-Mailbox]錯誤信息:" + errors);throw new Exception(errors);//記錄log信息 } }pipeline = null;runspace.Close();runspace = null;//return (result != null && result.Count > 0);return string.IsNullOrEmpty(errors);}catch (System.Exception ex){log.Info(identity + "賬戶Get-Mailbox調用異常:" + ex.Message);throw ex;}}

log4Net配置節：

<?xml version="1.0" encoding="utf-8" ?> <configuration><configSections><section name="log4net" type="log4net.Config.Log4NetConfigurationSectionHandler,log4net" /></configSections><log4net><appender name="ErrorLog" type="log4net.Appender.RollingFileAppender,log4net" ><param name="File" value="D:\\Logs\\Error\\" /><param name="AppendToFile" value="true" /><param name="RollingStyle" value="Date" /><param name="DatePattern" value="yyyy-MM\\&quot;ServiceError-&quot;yyyy-MM-dd&quot;.txt&quot;" /><param name="StaticLogFileName" value="false" /><layout type="log4net.Layout.PatternLayout,log4net"><param name="ConversionPattern" value="%d{yyy-MM-dd HH:mm:ss} %m%n" /></layout></appender><root><level value="ALL" /></root><!-- 服務錯誤日志--><logger name="ErrorLog"><level value="INFO" /><appender-ref ref="ErrorLog" /></logger></log4net> </configuration>

AssemblyInfo.cs頂部加入如下代碼：

[assembly: log4net.Config.Repository("PowerShellExInfo")] [assembly: log4net.Config.XmlConfigurator(ConfigFile = "log4net.config", Watch = true)]

?

以上都做好后，創建com組件。將log4Net配置文件放到引用組件同目錄下。本來以為這樣就可以了，可是操作過程中發現并沒有記錄異常日志信息，網上找了三天，皇天不負有心人啊，終于在國外論壇找到解決方法。log4net配置文件應放到在system32目錄下，這樣日志就能記錄了。OK
