arrays

Expand Post »

Hi
I have a code here composed of Array. I would like to know what does this mean here: (please see the red text)
What does it mean?

Thanks & regards

ArrayList numbers = new ArrayList();
string yourValue;

Console.WriteLine("Give the value (b to end)");
Console.WriteLine();

do
{
Console.WriteLine("Give the value:");
yourValue = Console.ReadLine();

if (yourValue == "b")
break;
numbers.Add(Convert.ToInt32(yourValue));
}
while (true);
System.Collections.IEnumerator Enumerator = numbers.GetEnumerator();
while (Enumerator.MoveNext())
Console.WriteLine(" " + Enumerator.Current);

Re: arrays

this will loop through all the values in your array
IEnumerator basically means you can use it to iterate your data

lets say you have 1, 5, 3, 8 in your array

this will print out

1 5 3 8

Re: arrays

so in looping all the valus I always need this one:
System.Collections.IEnumerator Enumerator = numbers.GetEnumerator();
while (Enumerator.MoveNext())
Console.WriteLine(" " + Enumerator.Current);

is that right?

thanks

Re: arrays

you don't always have to use that way, but you can

you could also do something like this

C# Syntax (Toggle Plain Text)
foreach(int num in numbers)
{
  Console.WriteLine(" " + num);
}
foreach(int num in numbers)
{
  Console.WriteLine(" " + num);
}

Re: arrays

i tried this but when I write the "b" to end, I got an error. this is what I've done.

C# Syntax (Toggle Plain Text)
 while (true);
            //this will loop through all the values in your array IEnumerator basically means you can use it to 
            //iterate your data
            foreach (int num in numbers)
            {
                Console.WriteLine(" " + num);
            }
 
 
 
            //System.Collections.IEnumerator Enumerator = numbers.GetEnumerator();
            //while (Enumerator.MoveNext())
            //    Console.WriteLine(" " + Enumerator.Current);
        }
 while (true);
            //this will loop through all the values in your array IEnumerator basically means you can use it to 
            //iterate your data
            foreach (int num in numbers)
            {
                Console.WriteLine(" " + num);
            }


            
            //System.Collections.IEnumerator Enumerator = numbers.GetEnumerator();
            //while (Enumerator.MoveNext())
            //    Console.WriteLine(" " + Enumerator.Current);
        }

Re: arrays

its because you are using an untyped list for one, but you didn't have an else statement

C# Syntax (Toggle Plain Text)
if (yourValue == "b")
{
break;
}
else
{
numbers.Add(Convert.ToInt32(yourValue));
}
if (yourValue == "b")
{
break;
}
else
{
numbers.Add(Convert.ToInt32(yourValue));
}

also you could use List instead of ArrayList

C# Syntax (Toggle Plain Text)
List<int> numbers = new List<int>();
List<int> numbers = new List<int>();

List<int> numbers = new List<int>();

You don't really need the typed List for what's going on, it's just a nice thing to have in terms of type safety...
