com+组件日志记录（log4net）

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<PSObject> 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：

<?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>

        <!-- 服务错误日志-->
        <logger name="ErrorLog">
            <level value="INFO" />
            <appender-ref ref="ErrorLog" />
        </logger>
    </log4net>
</configuration>

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
