1. Maybe.
If you intend code benchmarks in the beta release, then Trace
makes sense but would necessitate clean up before final release.
2. ... At top of code
using System.Diagnostics;
... In Main function
int[] myArray = new int[500];
int i;
for (i = 0; i < 10000; i++)
{
Debug.Assert(i < 4999, "The test loop has reached 5000 iterations",
"An error is pending - please step through debug");
if (i == 4999)
{
Console.WriteLine("This array element {0} is going to break things!", myArray[1000]);
}
}
3. False, a finally code block always executes
4. ... At start of class
enum orientation : byte
{
north = 1,
south = 2,
east = 3,
west = 4
}
... In Main function
/* The checked function tests conversion of data types.
* Assigning a value to "myByte" (as instructions suggested) precludes
* conversion test to "orientation" since both are byte data types.
* Following code tests string input conversion */
try
{
orientation myDirection;
Console.WriteLine("Enter a whole number to consider:");
myDirection = checked((orientation)Convert.ToByte(Console.ReadLine()));
Console.WriteLine("Here's your solution: {0}", (orientation)myDirection);
}
catch (OverflowException)
{
Console.WriteLine("The number you entered is out of bounds for the orientation data type");
}
catch (Exception e)
{
Console.WriteLine("An unexpected error resulted from your input: {0}", e.Message);
}
