ObjectsLogAppender

Custom appender for log4net. Gives you the ability to write any object to log.
You can configure the members that you want to write to log.

####Supports:

• Properties
• Public fields
• Private fields

####Example of usage:
Assume we have Class SomeClass with some properties and we want only to write LastName and ID.
Also we have ComplexClass with array,list,property Of Class Y that have IntY property, and a property of Class X that have StringX property and also have private int field
The Code

 var complexObject = new ComplexClass()
            {
                CoolNamesInList = new string[] {"eliran", "moyal"},
                CoolNumbersInArray = new int[] {1, 2, 4, 8, 16, 32, 64},
                Y = new ClassY()
                {
                    IntY = 13,
                    StringY = "Y Y Y",
                    X = new ClassX()
                    {
                        IntX = 12,
                        StringX = "X X X"
                    }
                }

            };
 complexObject.Y.X.SetPrivateInt(14);
 log.Debug(complexObject);
 
 var eliran= new SomeClass()
            {
                FirstName = "eliran",
                LastName = "moyal",
                ID = 11

            };

  log.Debug(eliran);
  

the result will be:

2014-08-07 21:22:57,489 [1] DEBUG Log4ChecksConsole.LoggingClass LastName="moyal";ID=11
2014-08-07 21:22:57,517 [1] DEBUG Log4ChecksConsole.LoggingClass CoolNumbersInArray=[1,2,4,8,16,32,64];CoolNamesInList=["eliran","moyal"];IntY=13;StringX="X X X";_intXPrivateField=14
