Subject RE: AdoNetAppender Connection String

Hi Dag.

Thanks for your comments.

The appenders collection returned only ever has one item in it - a TextWriterAppender.  It
is as if the config file is not being found and a default appender is being used.

Any other thoughts?

Config file follows:

<log4net>
    <root>
        <level value="INFO"/>
      <appender-ref ref="LogToSqlServer"/>
    </root>

    <appender name="LogToSqlServer" type="log4net.Appender.AdoNetAppender">

        ... lots of stuff in here ...

    </appender>
</log4net>

Shouldn't be a TextWriterAppender there. Can you post your configuration file?

Not answering your question but as a workaround you could loop through the list of appenders
returned and find the first (or named) instance of AdoNetAppender you're looking for.

Regards,

Dag

Subject: AdoNetAppender Connection String

Hello.

I am trying to retrieve the connection string within my logging.config (a separate file outside
the web.config in case that is significant) file.

I am using the code below but it seems to use a default(?) logger which is not defined in
my config file (a TextWriterAppender).

I am wondering if this is occurring because the config file cant be located or the code I
am using is just wrong.

Pointers/Tips/Advice very much appreciated.

        internal static string LoggerConnectionString
        {
            get
            {
                // determine the logging hierarchy
                Hierarchy log4netHierarchy = LogManager.GetRepository() as Hierarchy;

                // magic number used because there should only ever be one appender defined
in this application
                // the appender variable evaluates to null!
                AdoNetAppender appender = log4netHierarchy.Root.Appenders[0] as AdoNetAppender;

                // return connection string if it is found
                return appender.ConnectionString ?? string.Empty;
            }
        }
