Not all exceptions are errors. Many developers have incorrectly been taught or assume that all exceptions are errors. In fact, a key clue is that they are called exceptions and not errors.

Dictionary.com defines an exception as something excepted; an instance or case not conforming to the general rule. Exceptions in code are used to modify standard program flow (i.e. the general rule) and communicate information to a higher calling level where they are trapped....

In the Overview of Editing and Deleting Data in the DataList tutorial, we created a DataList that offered simple editing and deleting capabilities. While fully functional, it was hardly user-friendly, as any error that occurred during the editing or deleting process resulted in an unhandled exception. For example, omitting the product s name or, when editing a product, entering a price value of Very affordable! , throws an exception. Since this exception is not caught in code, it bubbles up to t...

One of the key features of the ADO.NET DataSet is that it can be a self-contained and disconnected data store. It can contain the schema and data from several rowsets in DataTable objects as well as information about how to relate the DataTable objects—all in memory. The DataSet neither knows nor cares where the data came from, nor does it need a link to an underlying data source. Because it is data source agnostic you can pass the DataSet around networks or even serialize it to XML and pass it ...

Exceptions in .NET are the fundamental mechanism by which errors and other exceptional conditions are communicated. Exceptions are used not only to store information about such issues but also to propagate that information in object-instance form through a call stack. Based on the Windows structured exception handling (SEH) model, only one .NET exception can be "in flight" at any particular time on any particular thread, a restriction that is usually nary a thought in developers' minds. After al...

Have you ever written a partial trust ASP.NET application and gotten a SecurityException?

But SecurityException is a bit odd compared to other exception classes. For example, it doesn’t directly expose the InnerException property, even though you can still get at it throu...
