Examples Using Specific catch Clauses
In the following code, the catch clause of a previous example has been modified to specifically
handle exceptions of the DivideByZeroException class. While in the other example, the catch
clause would handle any exception raised in the try block, the current example will only han-
dle those of the DivideByZeroException class.
int x = 10;
try
{
int y = 0;
x /= y; // Raises an exception
} Exception type
↓
catch ( DivideByZeroException )
{
...
Console.WriteLine("Handling an exception.");
}
For example, you could further modify the catch clause to use an exception variable. This
allows you to access the exception object inside the catch block.
int x = 10;
try
{
int y = 0;
x /= y; // Raises an exception
} Exception type Exception variable
↓ ↓
catch ( DivideByZeroException e )
{ Accessing the exception variable
↓
Console.WriteLine("Message: {0}", e.Message );
Console.WriteLine("Source: {0}", e.Source );
Console.WriteLine("Stack: {0}", e.StackTrace );
}
This produces the following output:
Message: Attempted to divide by zero.
Source: Exceptions 1
