• How to modify raw HTML of ASP.NET page on PreRender?

  - by ace

  I want to access the raw HTML code that my ASP.NET System.Web.UI.Page is about to render. How can i do that? Is there a property or method like System.Web.UI.Page.HTML or something like that. I know I could loop through the Controls List of the page and get access to all the Literal Controls etc, but I was wondering if there's a direct property or method that can return me the raw html, which I can modify just before rendering the page.

• If you stick to standard coding in .NET, is there reason to manually invoke the GC or run finalizers

  - by Matt

  If you stick to managed code and standard coding (nothing that does unconventional things withe CLR) in .NET, is there any reason to manually invoke the GC or request to run finalizers on unreferenced objects? The reason I ask is thaty I have an app that grows huge in Working Memory set. I'm wondering if calling System.GC.Collect(); and System.GC.RunFinalizers(); would help, and if it would force anything that wouldn't be done by the CLR normally anyways.

  The .NET framework provides a few handy general-use delegates for common tasks, such as Predicate<T> and EventHandler<T>. Is there a built-in delegate for the equivalent of CompareTo()? The signature might be something like this: delegate int Comparison<T>(T x, T y); This is to implement sorting in such a way that I can provide a lambda expression for the actual sort routine (ListView.ListViewItemSorter, specifically), so any other approaches welcome.
