Chapter 6 Quick Reference
To Do this
Throw an exception Use a throw statement. For example:
throw new FormatException(source);
Ensure that integer arithmetic is
always checked for overflow
Use the checked keyword. For example:
int number = Int32.MaxValue;
checked
{
number++;
}
Catch a specific exception
Write a catch handler that catches the specific
exception class. For example:
try
{
...
}
catch (FormatException fEx)
{
...
}
Catch all exceptions in a single
catch handler
Write a catch handler that catches Exception. For
example:
try
{
...
}
catch (Exception ex)
{
...
}
Ensure that some code will always
be run, even if an exception is
thrown
Write the code inside a finally block. For example:
try
{
...
}
To Do this
finally
{
// always run
}
