i have tried to surf the internet but i could not get anything related to what i want.
This is in relation to ASP.Net. But could be any other instance as well.
Following is my attribute
class SomeAttribute :Attribute
{
string someparam;
string SomeParam
{
get{ return someparam;}
set { someparam = val;}
//the value generated for someparam is dynamically generated with respect to some attribute present in the request header.
}
}
it's similar to the [Authorize] attribute that .net uses in its asp .net memberships to validate if the user has logged in and it redirects him back to log in page if validation fails.
I have an attribute associated with a method like below:
[SomeAttribute]
public void someFunction
{
//i want to retrieve here the value of someparam jus generated before entering this method.
}
Note that i don't pass any value or used any named properties in this attribute. It is simply going to check a condition for me whenever the method is called and return true or false and accordingly the function is either called or not.
In my case, After validating, it generates a value and that value has to be shared with the function to which it is associated 'somefunction'.
i know reflections can help me get the attributes associated with a function and the value of its properties.
But here i dont want to fetch the value from some other function. And i dont want to just fetch the attribute either.
As i mentioned earlier when the function is called the attribute will work upon that. What the attribute does is fetches some data from request header and does some processing and generates a value. Now this value has to be passed on to the function just after that.
