网上找了一个操作powershell的com+组件源码，配置好后，发现启用邮箱不稳定。因此在代码中用log4net加入异常日志记录。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
     
       result = pipeline.Invoke();                    if ((pipeline.Error != null) && (pipeline.Error.Count > 0))                    {                        foreach (object obj2 in pipeline.Error.ReadToEnd())                        {                            errors = errors + obj2.ToString() + "|";                        }                        //记录log信息                        log.Info(identity + "PipeLine[Get-Mailbox]错误信息:" + errors);                        throw new Exception(errors);//记录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 + "账户Get-Mailbox调用异常:" + ex.Message);                throw ex;            }        }
     

log4Net配置节：

AssemblyInfo.cs顶部加入如下代码：

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

 

以上都做好后，创建com组件。将log4Net配置文件放到引用组件同目录下。本来以为这样就可以了，可是操作过程中发现并没有记录异常日志信息，网上找了三天，皇天不负有心人啊，终于在国外论坛找到解决方法。log4net配置文件应放到在system32目录下，这样日志就能记录了。OK
