Assembly attribute ???

[serge calderara]

Dear all,

In my assembly info file I have such kind of default
information :

<Assembly: AssemblyTitle(" ")>
<Assembly: AssemblyDescrip tion("")>
<Assembly: AssemblyCompany ("")>

Can I add any other type of information I want like as
follow :
<Assembly: AssemblyKeyCode ("3215462452158 ")>

If yes how can I access that key from code?

thanks for your information
regards
serge

Yes. Look in the documentation on how to create your own Attribute. It is
basically a class inheriting from Attribute with an attribute on itself
telling the compiler here you are allowed to put it.
If yes how can I access that key from code?

Using reflection. Get ahold of the Assembly "object" (yes, it is an object,
too) for the assembly, and call the GetCustomAttrib utes method on it.

Assembly a; // which you can get from a type when you have it

AssemblyKeyCode Attribute [] kcaa =
a.GetCustomAttr ibuges(typeof(A ssemblyKeyCodeA ttribute));

The rest is in the documentation.

Thanks for your reply...

Is there a way to change assembly attribute during runtime?

In fact what I am thinking of is a way of having a kind of
licence activation for our asembly when distributed.
I was thinking to handle it in the following way:

1- I scann first for the existance of the assembly in the
system

2- then I check th MAC adress of the install system
3- then I combine that mac adress with assembly product
code and may be write thea crypted code somewhere

4- during runtime if that code is valid, I will check one
assembly atrtribute which could be AsssemblyLicCou nter

if this lic Counter = 2 then it means that it is able to
use 2 licence, when one is used i decrease that counter by
1, if it reach 0 then he cannot use any extra licence
until we provide hime an extension.

Does it sounds something simple or too crazy or too
complex?

In addition I woul like to get that licence installed in
only one system, in order to avoid copy

thanks for your comments
