c# - Override property setter and getter

Question

Is there a way to override the setter and getter of an auto property with an attribute?

like this:

[CustomAttribute]
public int Value { get; set; }

...

public class CustomAttibute : Attribute
{
    public override NotExistingPropertySetter(object value)
    {    
        if (((int)value) < 10 )
        {
            value = 10;
        }
    }
}

Answer 1

No. An attribute is never "executed". You would need to build a construct looking for the attribute and doing something if it's found.

AoP (aspect oriented programming) in .NET is only possible by using third party software like PostSharp.
