aspx thread: Joining items in an array

I can split a string into an array:
string myString="this,is,a,test";
char[] separator={","};
string[] myWords;
myWords=myString.Split(separator);
but I can't figure out how to do the other way round. ie. Join the items in
an array into a string.

Julian,
Actually you already know. :)
It's the static overloaded method, String.Join()

Thanks Dan, I think I'd confused myself on this one. Maybe it was because VS
intellisense wasn't showing it. But now I can see it my book. Anyway, I've
another question for you, if you don't mind? How can I split a string based
on multicharacter delimiters. For example, my delimiter is ##. The code
below produces erratic results. It seems to me that using the Split function
only accepts an array of single characters.
string myString="this##is##a##test";
char[] separator={"#","#"};
string[] myWords;
myWords=myString.Split(separator);

Use String.Split with char delimiters, Regex.Split with string
delimeters.
Here's an example of using Regex.Split...
<code buildString="csc /r:System.dll ...">
using System;
using System.Text.RegularExpressions;
public class Test
{
public static void Main()
{
Console.WriteLine("{0}{1}",Regex.Split("a##b", "##"));
}
}

Thanks Dan, I'll give that a shot. I'm slowly but surely getting my head
around OOP.

Hi Dan, thanks for the tip about using RegularExpressions. Everything works
fine now.
