Get the attributes from the interface methods and the class methods

Whats the best approach for getting the attribute values from a classes methods and from the interface methods when the methods are overloaded?

For example I would want to know that in the following example the Get method with one parameter has the two attributes and the values are 5 and "any" while the other method has attributes with values 7 and "private".

public class ScopeAttribute : System.Attribute
{
    public string Allowed { get; set; }    
}

public class SizeAttribute : System.Attribute
{
    public int Max { get; set; }
}

public interface Interface1
{
    [SizeAttribute( Max = 5 )]
    string Get( string name );

    [SizeAttribute( Max = 7 )]
    string Get( string name, string area );

}

public class Class1 : Interface1
{
    [ScopeAttribute( Allowed = "any" )]
    public string Get( string name )
    {
        return string.Empty;
    }

    [ScopeAttribute( Allowed = "private" )]
    public string Get( string name, string area )
    {
        return string.Empty;
    }
}
