How do i split a String into multiple values?

How do you split a string?

Lets say i have a string “dog, cat, mouse,bird”

My actual goal is to insert each of those animals into a listBox, so they would become items in a list box.

but i think i get the idea on how to insert those items if i know how to split the string. or does anyone know a better way to do this?

im using asp c#

Method 1

    string[] tokens = text.Split(',');

    for (int i = 0; i < tokens.Length; i++)
          yourListBox.Add(new ListItem(token[i], token[i]));

Method 2

Have you tried String.Split? You may need some post-processing to remove whitespace if you want “a, b, c” to end up as {“a”, “b”, “c”} but “a b, c” to end up as {“a b”, “c”}.

For instance:

private readonly char[] Delimiters = new char[]{','};

private static string[] SplitAndTrim(string input)
    string[] tokens = input.Split(Delimiters,

    // Remove leading and trailing whitespace
    for (int i=0; i < tokens.Length; i++)
        tokens[i] = tokens[i].Trim();
    return tokens;

Method 3

Needless Linq version;

from s in str.Split(',')
where !String.IsNullOrEmpty(s.Trim())
select s.Trim();

Method 4

Or simply:


Or this to ensure the strings are trimmed:

targetListBox.Items.AddRange((from each in inputString.Split(',')
    select each.Trim()).ToArray<string>());

Oops! As comments point out, missed that it was ASP.NET, so can’t initialise from string array – need to do it like this:

var items = (from each in inputString.Split(',')
    select each.Trim()).ToArray<string>();

foreach (var currentItem in items)
    targetListBox.Items.Add(new ListItem(currentItem));

Method 5

It gives you a string array by strVar.Split

"dog, cat, mouse,bird".Split(new[] { ',' });
