C# Exceptions

C# allows a programmer almost all of the functionality provided by the CLR. To demonstrate exception handling in a C# environment, look at the next example that generates exceptions of various types. Because the code is rather long, the listing has been split into small sections. The full source for Listings 15.4–15.8 is in the BasicExceptions directory. Listing 15.4 shows an example of how C# code can be used to catch a DivideByZeroException.

Listing 15.4. Catching a Divide-By-Zero Exception

// Try a divide by zero try { int x = 0; x = 1/x; } catch(DivideByZeroException e) { // Dump interesting exception information Console.WriteLine (e.ToString()); }

When the exception is caught, the output looks like this:

 System.DivideByZeroException: ...
