Review the solution for the try-catch challenge

The following code is one possible solution for the challenge from the previous unit:

try
{
    Process1();
}
catch
{
    Console.WriteLine("An exception has occurred");
}

Console.WriteLine("Exit program");

static void Process1()
{
    try
    {
        WriteMessage();
    }
    catch
    {
        Console.WriteLine("Exception caught in Process1");
    }

}

static void WriteMessage()
{
    double float1 = 3000.0;
    double float2 = 0.0;
    int number1 = 3000;
    int number2 = 0;

    Console.WriteLine(float1 / float2);
    Console.WriteLine(number1 / number2);
}

In this solution, the Process1 method has been updated to use the try-catch pattern. The WriteMessage method is called in the try code block, which enables Process1 to catch the exception before it's caught by the catch clause in the top-level statements.

Running this application generates the required output:

∞
Exception caught in Process1
Exit program

Notice that since the exception is caught inside Process1, the catch code block in the top-level statements is not executed. The benefits gained by catching exceptions at different levels in the call stack becomes more evident when specific exception types are being caught. You'll examine exception types in the next unit.

If you succeeded in this challenge, congratulations! Continue on to the next unit.
