ASP MVC C#: Is it possible to pass dynamic values into an attribute?

Question

Okay I'm very new to C# and i'm trying to create a little website using ASP MVC2.

I want to create my own authorization attribute. but i need to pass some values if this is possible.

For example:

    [CustomAuthorize(GroupID = Method Parameter?]
    public ActionResult DoSomething(int GroupID)
    {
        return View("");
    }

I want to authorize the access to a page. but it depends on the value passed to the controller. So the authorization depends on the groupID. Is this possible to achieve this in any way?.

Thanks in advance.

Use the value provider:

public class CustomAuthorizeAttribute : FilterAttribute, IAuthorizationFilter
{
    public void OnAuthorization(AuthorizationContext filterContext)
    {
        var result = filterContext.Controller.ValueProvider.GetValue("GroupId"); //groupId should be of type `ValueProviderResult`

        if (result != null)
        {
            int groupId = int.Parse(result.AttemptedValue);

            //Authorize the user using the groupId   
        }
   }

}

You get it from Request.Form

public class CustomAuthorizeAttribute : AuthorizeAttribute
{
    protected override bool AuthorizeCore(HttpContextBase httpContext)
    {
       //httpContext.Request.Form["groupid"]
        return base.AuthorizeCore(httpContext);
    }
}

You could use Request["groupID"] then.
