I have a lots of forms in my project.
my url was like that

www.xxx.com/pages/frmLoanReq.aspx?moduleID=401

And I get id by QueryString on Page_Load on every form like  :

string strLogRef = Request.QueryString["moduleID"].ToString()

But now I send id by Encrypt :
www.xxx.com/pages/frmLoanReq.aspx?moduleID=ASLDK7234KAMV84;

I want to general code for not changing forms codes.

Something like this for general :

For example Request.QueryString["moduleID"].ToString() = DECRYPT( Request.QueryString["moduleID"].ToString() ).

Or what can I do?

a small note on this first:

> string strLogRef = Request.QueryString["moduleID"].ToString()
it is already a string, ToString() is not necessary.... ;-)



So you want something like:

string strLogRef = Decrypt(Request.QueryString["moduleID"]);
but what do you mean with "general"? If you use C# 3.0 (in .NET 3.5) you can create an extension method for the Request, say, "DecryptedQueryString". When you call that, it would look something like the following:

string strLogRef = Request.DecryptedQueryString["moduleID"];
is that what you mean to do? Or is the first version enough?

Ah, I didn't know you meant that, to me it sounded that you already had an encryption module. So, what can I help you further with?

Note that it is a custom (but not compulsory) that when you come with the answer yourself, esp. if it is slightly off the original question, to merit the experts that have spent time with you on the subject.

If you grade the comments, it won't cost you points (q. points will not be refunded when you find the solution yourself).
