Business entity with additional properties

[Stefano]

Hi all,

I'm designing classes for my application.

I'd like to create a business entity that could be expanded with other properties
when needed.

For example, this could be my entity:

MyBusinessClass
-> Property1
-> Property2
-> ...
-> OtherProperties

The "OtherProperties" property of the class could expose a name value collection
with the other properties associated to the entity.

Now, the question is:
can I use System.Configuration.SettingsProperty class to define the additional
property, and so declare the "OtherProperty" as SettingsPropertyCollection?

I mean: has someone used this before? Are this classes designed for this
purpose?

Thanks

Bye

Stefan

Stefano,

You ^could^, but I don't think that this would be a good idea. The
reason for this is that every instance of your object (with each instance
representing separate entities) would share the same values, which is what I
am sure you don't want.

Hope this helps.

I'm not sure that values will be shared.
Why did you say that?

I'm looking inside, using a reflector... that classes (SettingsProperty and
SettingsPropertyValue) doesn't have static members.

So, what is the correct use that we can do about this classes?

Thanks

Stefano,

It doesn't have static members, but the classes are meant to store
values that are used application-wide, not instance-wide.

Hello Nicholas Paldino [.NET/C# MVP],

thanks for the answer. You're right.

Anyway...

It could be great if the BCL had supplied a class that we could have used
in order to define a property, like the one that Vadym suggests:

public class CustomProperty
{
Name
PropertyType
Value
SerializedValue
....
}
