string[] words=mysentance.Split(" ");
/*

* words[0] = "This"
* words[1] = "is"

Please post a snippet of the code that you're using.
I can't seem to find anything wrong with the code posted by Plater.

Except his abominable spelling! ;D

I am a horrible speller, and English is my first language.

The code I gave was for C#, AND I found my mistake:

string mysentance = "This is an example sentance";
string[] words = mysentance.Split(" ".ToCharArray());
/*
* The results should be something like:
* words[0] = "This"
* words[1] = "is"
* words[2] = "an"
* words[3] = "example"
* words[4] = "sentance."
*/

or...

string[] words = mysentance.Split(' ');

just use ' instead of " to specify its a char not a string.

string[] words = mysentance.Split(' ');

It's gotta be a char array so you need

string[] words = mysentance.Split(new char[]{' '});
 

Which is why I went with the " ".ToCharArray()

Seems sorta strange.
In VB.NET it's

Dim words() as String = mysentance.Split(" "c)
'note that the " "c specifies that it is a character not a String.
 

Why would the Split function need an array of delimiters?

[Logan1337]

Split() doesn't require an array, but supports splitting on multiple delimiters. I seem to recall it working fine with just Split(' '), perhaps because the compiler can implicitly cast a single character into an array of size 1, I'm not sure. There are several overloads for the method as well, unless I'm confusing it with Replace().

The local MSDN help is much more clear on the matter, but it requires an array of params.
