Try/Catch Blocks Can Hurt Performance Significantly

Over at Programmers Heaven.com, there’s an interesting article on the potential performance impact of try/catch blocks. The article concluded that the average cost of a try/catch block is essentially nothing (sorry there’s no author information on the post), and that .NET/C# programmers should not think twice about using try/catch blocks. The author is right that a try/catch block has essentially zero cost. However, like most coding performance issues, exceptions and try/catch blocks do not have performance implications until they occur in some type of loop.
