Exception Handling in VB.Net
One of the most reputable changes in the Visual Basic language is the introduction of structured exception handling in VB.NET. While the latest version of the language still supports the On Error Goto type of error handling, it's not preferred; instead, you should use structured exception handling.
VB.NET now supports the Try Catch exception blocks and Try Finally resource protection blocks. Here is more information about both types of structured exception handling blocks, along with code samples.
Try ... Catch
The Try Catch block allows you to catch and handle errors for which the developer can specify a resolution. The basic format of the block is:
Try ... Finally
The Try Finally blocks are usually used in order to ensure that allocated resources are being cleaned up. These blocks allow you to catch and handle errors, as well as execute a section of the code regardless of whether there is an error. The basic format of the block is listed below:
Note: In real applications, you will often need to combine or nest the Try Catch and Try Finally blocks to design a more flexible error handling routine.
Re: Exception Handling in VB.Net
I have always wondered if VB .NET copied this from Java as I am very familiar that Java uses Try catch statements in the same way. What do you all think?
