C# - Which Exceptions Should A Program Never Attempt To Recover From?
Mar 13, 2012
Exceptions can have different degrees of impact on a program. For example a program should probably abort if OutOfMemoryException is raised, but it is possible to safely and appropriately handle System.Data.SqlClient.SqlException without putting the program in an unknown state.
I do understand that any exception has the potential to put the program in an unstable state if it is not properly handled. Are there exceptions that should never be handled beyond simply logging and throwing up the stack?

And this section of code is highlighted: HTML WebBrowser1.Document.GetElementById("ctl03$Login$username$input").SetAttribute("value", TextBox1.Text)
