Custom attributes to define min, max, ... value on numerical properties

Re: Custom attributes to define min, max, ... value on numerical properties

Polo,

I believe the static property on each numeric type is MinValue and
MaxValue for the min and max values in that range respectively.

Hope this helps.

Re: Custom attributes to define min, max, ... value on numerical properties

Sorry but It is not my problem.

I woul like to define custom attributes to set min, max, number of digits
by exemple :
[MinValue(0)]
[MaxValue(100)]
...
public int Temperature
{
...
}

Somebody has you it already defined this type of attribute.

Re: Custom attributes to define min, max, ... value on numerical properties

Pol,

Well, there is no attribute like that, but you can always create your
own. You just have to derive a class from the Attribute class and then add
your properties, and the appropriate constructor syntax.

Re: Custom attributes to define min, max, ... value on numerical properties

Nicholas,

It would be nice if these attributes could also perform corresponding data
validation. I have seen an article called "Aspect-Oriented Programming" that
explained such tricks. While I find this idea very appealing, its
implementation seems to be too complicated in the .NET Framework.

Re: Custom attributes to define min, max, ... value on numerical properties

Dmitry,

They can provide indicators as to what the data validation should be.
Attributes are nothing more than meta-data, and they should have no
executable code in them (at least, when loosely defining "executable "). You
need to have code that performs actions based on the meta-data, which is in
fact what the implementation of Aspect Oriented Programming that you saw (I
believe we saw the same article) does.
