RE: [nant-dev] RE: [Nant-users] Adding Tasks 0.7.9 vs 0.8
Granted, we're getting off topic... but Bill's Kung-Fu is clearly
stronger than mine and I wish to lean. (And figure it might be
instructive to others)
So Bill,
Am I understanding correctly that this defeats the security of scoping
something as private? Are there limits to this? (Like does this work
across assemblies?)
(Yah, I know I could see for myself, but I'm late for work.)
:)

NAnt uses reflection in combination with the TaskAttribute
to match your attributes up with your properties and a privately
scoped property not only won't show up in reflection,
but NAnt wouldn't be able to assign to it even if it did.
You can view and set private members of a type. I have an example
below[1] that shows setting a private field on a type as well as a
private property.
The reason this doesn't work with Nant is because the Nant code
specifically checks only Public properties. Line 130 of Element.cs:
PropertyInfo[] propertyInfoArray =
currentType.GetProperties(BindingFlags.Public|BindingFlags.Instance);
could be:
PropertyInfo[] propertyInfoArray =
currentType.GetProperties(BindingFlags.NonPublic|BindingFlags.Instance);
Or:
PropertyInfo[] propertyInfoArray =
currentType.GetProperties(BindingFlags.NonPublic|BindingFlags.Public|Bin
dingFlags.Instance);

That will -definitely- keep it from working. NAnt uses reflection in
combination with the TaskAttribute to match your attributes up with your
properties and a privately scoped property not only won't show up in
reflection, but NAnt wouldn't be able to assign to it even if it did.
Hmmm... Is there a flag to AttributeUsage that can specify public
properties only? 'twould seem nice if the compiler could have caught
that and failed the compile.

Hi Bobby,
I wonder if you should have:
public string slnFileName
^^ Public access.
I'm not sure - without looking at your source, I couldn't be sure. All
of my attributes are marked as public, and I've never had this problem.
Simon.

Another problem that I am having is with setting the values
of the TaskAttributes. For instance if I have:
[TaskAttribute(solution,Required = true)]
private string slnFileName
{
get { return slnFileName_m; } set {
slnFileName_m=value;}
}
Whenever I try to reference the slnFileName_m variable, I
receive Null pointer errors. My .build file does have the
solution attribute along with a value within, but for some
reason, it doesn't seem to be transferring over to the
variable within the solution property? Any ideas as to what I
am missing?? Thanks
