My code has a split function that should split the text file of numbers.
I've run this in previous programs as it is here and it worked, but now it
wont work for some reason and returns System_String[]. I don't see a
difference in the previous code and what I have now. Can anyone find where I
went wrong? Thanks a bunch!

I'm sorry, I posted the code from the working program. The program I am
dealing with is the same as that code except as follows:
foreach (string aOutput in aColumn)
{
string[] aFields = aOutput.Split(n ew char [] {' '});
Console.WriteLi ne("aOutput" + " " + "aFields");
Console.WriteLi ne(aOutput + " " + aFields);
{
foreach (string aField in aFields)
{
if (aField.Length !=0)
{
AField = System.Convert. ToDouble (aField);
Console.WriteLi ne(">"+ AField +"<");
}
}
}
}
Console.ReadLin e();

Christine,
are you referring to the Console.WriteLi ne(aOutput + " " + aFields) line
that outputs System.String[]?
In that case the output correct, since aFields is really an array of
strings, and it's ToString() method does not print out
the elements, but it's underlying type (inherited from Object). You should
use aFields[<counter>] to print out an element.
The rest of the code should still work.

You get "System.Str ing[]" when printing aFields to the console,
because it is a string array, not a string. If you want to print the
*contents* of the array, you will need to loop over its elements and
print them one at a time.

Right - you're trying to write out a string array, and Array.ToString
just prints out the type. What did you want it to do?

Hi All,
What I want to is using a string as PATTERN in a split function. This makes

For example:

My goal is to accept input from the user into a text box and then
parse the data using split(). The first step is this tiny program to
test the split() function. It runs in IE, but in Mozilla it just
hangs and keeps loading forever. I checked around on the web and in
USENET, but I haven't seen any mention of split() not working in
Mozilla. Thoughts? Thanks in advance.

Hey Guys.
If I have a string say "abcdefg" how do i split the string without delimiters.
What i need is a list containing each of the chars:
e.g.
The string.split() method wont work as it requires a delimiter within the string to split on and returns .
Just going to use it for some error checking and validation used in a wx.TextCtrl in my GUI.
Cheers.
