Strange Request - Stop All Future Processing And Reload Page Instead? (or Change My Design)

I want to be able to (in code) tell the page to refresh at that point ignoring anything else it was going to do.

Explanation:

I have a property lets call it AllUsers

AllUsers
{
return Database.GetAllUsers();
}

Now I have put it like this because in my code I want to just use this property to browse all the users and not have to check if its null or not up to date. The problem is if my method .GetAllUsers() throws an exception e.g. database is unavailable. If this happens I want to display a message to the user and reload the page to its initial state.

e.g. something like this

AllUsers

{
try
{
return Database.GetAllUsers();
}
catch(Exception e)
{
AbortAllCodeAndReloadAndDisplayMessage(e.Message);
}
}

Now I can reload the page using Response.AppendHeader("Refresh", "0;URL=ThisPage.aspx");

but how can I abort all code? because if I use this where I have placed my method the code will run and then reload on the next page load.

Should I change by property design? I wanted to have a property which would always be valid and up to date so any code using it wouldn't have to worrie
