Hi, how do I count characters in a string with C#?
Unity Answers is for Unity specific questions only.
Please ask language specific questions on a programming forum.
Also a 2 second Google search could have answered this question for you.
I did try google since that's the first thing I always do, and this is for unity 3D(thought I mentioned that, guess I left it out)
C# is not specific to Unity. It is C#.
Unity uses the MONO.NET framework which is almost identical to the Microsoft.NET framework.

May I ask how to implement it? Or an example please.
Kayden, I'd suggest doing this C# video course below, your questions are absolute basics of programming and it seems you are not ready to even ask questions on a forum.
Example: string value = "abcde"; int x = value.Length;
And, what Meltdown said. If you hope to make a game, you must learn to program.
wow... this thread was brutal... :)

Your millage may vary and this can be done a lot of ways and Length is the right choice, but here you go.
public class SillyStringQuestion
private string sentence;
public SillyStringQuestion(string theString)
this.sentence = theString;
public int CountCharsTheString()
int result = 0;
charArray = sentence.ToCharArray();
foreach(char character in charArray)
throw new Exception("bummer no data and stuff");

For those that are interested, this website has benchmarked at least a dozen different ways to count the number of times a character occurs in a string, using both single threaded and multithreaded techniques.
Basically, the winner is either the single or parallel for-loop implementations as follows where "ss" is the Search String, "ch" is the array of characters you're looking for.:
for (int x = 0; x < ss.Length; x++)
for (int y = 0; y < ch.Length; y++)
for (int a = 0; a < ss[x].Length; a++ )
if (ss[x][a] == ch[y])
//it's a match. Do what you need to.
