Can you pull the connectionString for a log4net AdoNetAppender from elsewhere in a web.config file?

Question

I already have a db connection string in my web.config file. I scanned the log4net docs, but can\'t seem to find a way to use it within the log4net section of my web.config

Answer 1

Create a class that extends AdoNetAppender - say, WebAppAdoNetAppender. Implement the ConnectionString property in that class, and retrieve the connection string from your web.config file in that property setter.

    
    ...

...

public class WebAppAdoNetAppender : log4net.Appender.AdoNetAppender
{
    public new string ConnectionString
    {
        get { return base.ConnectionString; }
        set { base.ConnectionString = ...   }
    }
}
