Sample text

This is especially annoying because FileNotFoundException is a perfectly good exception and doesn’t need to be wrapped in another type. When considering wrapping exceptions, consider the following guidelines: 44 • Evaluate how useful the additional information is going to be. What information would the developer get if the exception wasn’t wrapped, and would that be sufficient? Is the code going to be used by other developers on your team with access to the source (who can therefore just debug into it), or is it an API used by somebody else, where wrapping may be more useful?

Initialization If the default value of the field isn’t what is desired, it can be set in the constructor. If there are multiple constructors for the object, it may be more convenient—and less error-prone—to set the value through an initializer rather than setting it in every constructor. number = number; } int number; } class MyClass { public int counter = 100; public string heading = "Top"; private Parser parser = new Parser(100); } This is pretty convenient; the initial values can be set when a member is declared.

ReadLine()) ! ToInt32(line); CalculateAverage(count, sum); } } // always executed before function exit, even if an // exception was thrown in the try. WriteLine("Exception: {0}", e); } } } This example walks through a file, reading a count and sum from a file, and accumulates an average. What happens, however, if the first count read from the file is a zero? If this happens, the division in CalculateAverage() will throw a DivideByZeroException, which will interrupt the file-reading loop. Close() would have been skipped and the file would have remained open.
