Hi.
I've given the average program a shot. I'm not sure what to put in the try
block.
using System;
namespace Treehouse.Average
{
class Program
{
static void Main()
{
var runningTotal = 0.0;
var average = 0.0;
while (true)
{
// Ask user to enter a number or type "done" to see the average
Console.Write("Please enter a number or type \"done\" to see the average: ");
var entry = Console.ReadLine();
if (entry.toLower() == "done")
{
break;
average = runningTotal / average;
}
try
{
}
catch
{
Console.WriteLine("That is not valid input.");
continue;
}
}
}
}
}

231,248 PointsBased on the message in the "catch" block, it looks like you want to cover the conversion of the input into a number before performing calculations on it.
So at a minimum, the "try" block should contain the conversion of the input, perhaps something like this (assuming "numericValue" had been previously declared):
try
{
numericValue = Double.Parse(entry);
}
The "try" block can optionally also contain any other code that should be performed only if the conversion succeeds.
