Writting to a TextBox

[C#Schroeder]

I want to create an ArrayList of names ("Tony","Robin","Johnson") on
one page and then on another page I want to populate a TextBox field
with those names from the Arraylist. How do I populate the TextBox?

Enumerate the list, forming a string from the names (using whatever
delimiters, if any, you desire of course), and then set the text of the
TextBox to that string.

The best way to enumerate the list is:
string[] names = (string[])list.ToArray(typeof(string));
textbox1.Text = string.Join("\r\n",names);

Or
object[] names = list.ToArray();
string.Concat(names);

this might be better because the arraylist doesnt copy the internal array
for this but the string.concat does a bit more work. This would use less
memory though.

Scrub this one, the ToArray() does copy the array so the other one is better.

Or
object[] names = list.ToArray();
string.Concat(names);
