Sometimes you have to go through a loop once to get something to compare. Sometimes, you'd have to copy and paste your code before the while loop if you didn't want to use a do-while.

I understand that, but I don't see the need for it this time.

In this example, the only difference that it would make is that if you used a while instead of a do-while, you'd have to set your input char to 'Y' initially.
Except, in your code, you use a while loop, but it basically is a do-while because

Code:

((input = Console.ReadLine()) != "stop")

takes in the input before being compared.

No...

A do-while would loop through the entire code before testing.

What I'm saying is, you execute code that gets repeated everytime before you actually enter the loop. _________________

In my while loop, the Console.ReadLine() is the only thing that is executed before the loop. It could be done with a for loop too, though it'd be obnoxious and pointless:

Code:

for (input = Console.ReadLine(); input != "stop"; input = Console.ReadLine())
{
//...
}

In a do-while loop, the entire part of the loop is executed before the first test.

Look at this simulation:

Code:

blah blah...
Introduction...

Enter the first number, "stop" to exit.
stop
Invalid number
...

eh, semantics.
Refferring to the original code, a do-while would've been better than using a while loop which was what the

Ew...goto. Use a do while loop.

was referring to.

I just stated why a while would be better than a do-while. -_-;

where?
the original code didn't put the input into a variable during the compare. In that example, a do-while would've been better.

What's with the assignment at first?

I've cleared up the simulation if you didn't get it (I'm assuming you didn't, because you are acting like an idiot when I flatly put it out for you):

Code:

COMPUTER: <Introduction>
COMPUTER: Please enter first number. Type "stop" to exit.
USER : stop
COMPUTER: Invalid input.
COMPUTER: Please enter next number. Type "stop" to exit.
USER : stop
COMPUTER: Your average is ... Press enter to exit.

A while loop will check the condition before it begins the loop. If you don't assign it to true first, or don't assign it at all, it'll fuck up. _________________

Did you not read my code?

Code:

//using System.Collections.Generic;
//...
List<int> toAverage = new List<int>();
string input = String.Empty; int buffer; int currentAverage;

while ((input = Console.ReadLine()) != "stop")
{
if (!int.TryParse(input, out buffer))
{
Console.WriteLine("Invalid response.");
Console.WriteLine("Enter next number, or \"stop\" to exit.");
continue;
}

toAverage.Add(buffer);
currentAverage = CalculateAverage(toAverage);
Console.WriteLine("Current average: " + currentAverage.ToString());
Console.WriteLine("Enter next number, or \"stop\" to exit.");
}

Console.ReadLine();
}

private int CalculateAverage(List<int> values)
{
int sum = 0;
for (int i = 0; i < values.Count; i++) sum += values[i];
return (sum / values.Count);
}

Notice the

Code:

while ((input = Console.ReadLine()) != "stop")

First, it sets input to Console.ReadLine().
Then, it checks that to see if it isn't stop. If it isn't, then it goes on to do the code, if it is, it skips past the loop and doesn't run the code once.
