Comparing Object Values

[GBR]

I have a WebService method that sends to the client an object array received
from the server as a collection. Each element in the object array is a class
entity object. I would like to cache each of these class entities on the
client which is a windows forms. When ready to send back, I would like to
check if any of the class entity field values have changes.

I tried to implement .Equals but does not work. Since the Web Service
stripped the methods. What is the best way I can compare if the class entity
field values have changed?

Hello GBR,
Create a helper class that does the comparison. Anything that involves
generated classes will be lost when they are regenerated

Hi Dilip,

Could you please explain what you mean by Helper Class?

For now, I have implemented an alternate solution. I wanted to write
something generic to compare the object entity values received on the client
through web services. Since none of the object enetity methods cannot be
accesses on the client, I wrote a small function that uses reflection to peep
into the object entity class and compare the values associated with the
object entity fields.

I am not sure if this is a good way of doing it but it works. I pass 2
objects into this new function and it does the rest of the comparison.

Thanks,

Exactly what I meant by a Helper class.
