I am creating a simple word find. The users selects tiles that have letters on them.
After a word is selected, I need to compare it to a dictionary list of words.
The list is in csv format. There is no key value, just a single stream of words.
I have googled until I am blue in the face, I do not understand how to load a dictionary. Can anyone send me a link to an example that works.
You can load a csv with System.IO. Once you have the data loaded, you can move it into an array with string.Split. I would then suggest adding it to a HashSet for fast searching.
Dictionary has a specific meaning in C#. You don’t actually want to use a dictionary. So drop that off your search terms.
If it’s just a stream of words, separated by a comma or space, you can use a stream reader, and use comma or space as a delimiter.
Can you change your list from CSV to each word being on a single line? If so, you could use the code below that I’m using to read in a word list.
Also, in case this helps, there’s some good info on this page: http://wiki.unity3d.com/index.php/Choosing_the_right_collection_type
void LoadWordList(string filename, int minLength=2)
{
allWords = new List<string>();
using (StreamReader r = new StreamReader(filename))
{
string oneLine = "";
while ((oneLine = r.ReadLine()) != null)
{
// don't grab words below a minimum length
if (oneLine.Length > minLength)
{
allWords.Add(oneLine);
}
}
}
}
That’s modified from an example I found on StackOverflow. In my Awake() function I load it like this:
LoadWordList ("Assets/Resources/ospd.txt");
(You’d need to change the location of your word list, of course.)
And then when I want to see if the chosen word is actually in the list I do this:
if (allWords.Contains(chosenWord))
//do something here
Oh yeah, you can also pass in an optional “minimum length” when you load the word list – that way if you don’t want 1 or 2-letter words you just don’t load them into the list.
I hope that helps.

This worked great. Thank you! Although after importing system.io I had to explicitly call unitygame.random. not a big deal.
For some reason I thought Unity would handle it differently. Thank you everyone!
