Ron Grabowski commented on LOG4NET-31:
--------------------------------------

I've implemented property support for PatternConverters so
this syntax is supported:

<converter>
  <name value="user-converter" />
  <type
value="Company.Project.Logging.UserConverter,
Company.Project" />
  <property>
   <key value="address" />
   <value value="HomeAddress" />
  </property>
 </converter> 

Its easy to add property support to other objects like
Appenders but those are more well-defined than converters
(think plugins) and explicit properties should be used.

> Allow user to pass in additional parameters to
<converter> node via some kind of <property>
tag

> It would be useful if the user was able to supply
additional properties to the <convert> tag in the form
of:
>  <property name="foo"
value="bar" />
>  <property name="Hello"
value="World" />
> The code below uses a <property> node to
determine if the HomeAddress or the WorkAddress will appear
in the log message. If the parameter is not present, the
converter prints a default value.
>  <converter>
>   <name value="user-converter" />
>   <type
value="Company.Project.Logging.UserConverter,
Company.Project" />
>   <property name="Address"
value="HomeAddress" />
>  </converter>
>  <conversionPattern value="%p %d
%user-converter - %m%n" />
> The <property> tags would be accessible via a
Properties IDictionary. It would allow the converter to
perform additional logic on the base.Option that was passed
in:
>  public class MyConverter : PatternConverter
>  {
>   override protected void Convert(TextWriter writer,
object state) 
>   {
>    User user = GetUserByUserName(base.Option);
>    string address =
base.Properties["Address"] as string;
>    if (address != null && address.Length >
0)
>    {
>     if (user != null)
>     {
>      switch (address)
>      {
>       case "HomeAddress":
writer.Write(user.HomeAddress); break;
>       case "WorkAddress":
writer.Write(user.WorkdAddress); break;
>      }
>     }
>     else
>     {
>      // ???
>     }
>    }
>    else
>    {
>     // default display
>     writer.Write(user.HomeAddress); break;   
>    }
>   }
>  }
