.net-4.0

Hello,

I need to implement mechanism that compares two business objects and return the list of differences (past value, new value, isDifferenceBetter).

Because not all fields of class has to be compared and one fields need to be compared with different function then the other (sometimes < is better sometimes > is better ... ) I figured out that I need to implelemnt custom attribute and give it to each field that has to be compared in this object.

This attribute must have: - name - delegate or sth to point to the function which would be applied for comparision (dont know how to do it so far)

So could anyone suggest me if its a good idea? Maybe any other ideas.

Using attributes I would be able to use refflection to iterate through each field with attribute and invoke needed delegate.

thanks for help bye

Dynamic Type to do away with Reflection

as seen on West-Wind - Search for 'West-Wind'
The dynamic type in C# 4.0 is a welcome addition to the language. One thing I’ve been doing a lot with it is to remove explicit Reflection code that’s often necessary when you ‘dynamically’ need to walk and object hierarchy. In the past I’ve had a number of ReflectionUtils that used string based expressions… >>> More
