Count char in string

Hi guys, how can i count, how many times the SpaceBar is pressed while writing the string:
With this code, it sais that:
`cool' conflicts with a declaration in a child block

Code (csharp):

1. void Update () {
2.      cool=' ';
3.     foreach(char cool in abc)
4.     {asd=asd+1;}   
5. }
6.  

thanx

 

So, you want to count the number of occurrences of a specific character (space in your case) within a string? Here's one way:

Code (csharp):

1.  
2. string source = "This is my source string";
3. int count = source.Split(' ').Length - 1;
4.  

 

You're the best, thanks hope you'll help me in future

 

Scusme, and if i would like to count how many words are there?

 

If you assume words are delimited by the "space" character, it'd be almost exactly what I already posted, except that you wouldn't want to subtract 1 from the result. So:

Code (csharp):

1.  
2. string source = "This is my source string";
3. int wordCount = source.Split(' ').Length;
4.  

 

no, I mean:
string source = "This is my source string";
int wordCount = source.Split('source').Length;

 

Virtually the same thing.

Code (csharp):

1.  
2. // The important part is the string split, a more verbose way of representing it would be this:
3.  
4. string toSplit = "This is an example string.";
5.  
6. string[] split = toSplit.Split(' ');
7.  
8. foreach(string str in split){
9.     Debug.Log(str);
10. }
11.  
12. // This would output:
13.  
14. // "This"
15. // "is"
16. // "an"
17. // "example"
18. // "string."
19.  
20. // So the length of this "split" array is 5. To get the count of the spaces, he subtracted one
21. // To get the "word" count, just don't subtract that one
22.  
23. int wordCount = source.Split(' ').Length;
24.  
25. // This *may* not always be accurate though, depending on where your spaces are. A better way to handle it would be something like
26.  
27. int wordCount = 0;
28. foreach(string str in source.Split(' ')){
29.     if (string.isNullOrEmpty(str.Trim()) == false){
30.         wordCount++;
31.     }
32. }
33.  
34. // This way it only counts actual strings containing at least one non-space character
35. // Otherwise something like " This is an example string. "; may return incorrect results
36.  

 

Oh, in that case you don't want to split with a char, you want to split with a string.

Code (csharp):

1.  
2. int wordCount = source.Split("source").Length - 1;
3.  

If you want, you can use LINQ and get a nice reliable function that doesn't rely on a foreach loop to ensure accurate results in all conditions;

Code (csharp):

1.  
2. using System.LINQ;
3.  
4. int wordCount = souce.Count(s => s == "source");
5.  

EDIT:

Actually, if you don't want to use LINQ you can get accurate results from something like:

Code (csharp):

1.  
2. int count = (source.Length - source.Replace("source", "").Length) / "source".Length;
3.  

 

Ok, but if I would to count how many word like" source" are there in the string... I can't use myString.split('source'); ... so what have I to use in this case?

 

Too many characters in character literal

 

Yea, for some reason I was thinking that would work - guess not. Tested this and it works great:

Code (csharp):

1.  
2. public static class StringExtensionMethods {
3.     public static int WordCount(this string s, string word){
4.         return (s.Length - s.Replace(word, "").Length) / word.Length;
5.     }
6. }
7.  

Put that in it's own file, or on top of some other file - basically anywhere you want. Then you can do this...

Code (csharp):

1.  
2. string source = "This is my source string";
3. Debug.Log(source.WordCount(" source"));
4.  
5. // Outputs "1"
6.  

If you don't want to use extension methods, just use this function:

Code (csharp):

1.  
2. public static int WordCount(string s, string word){
3.         return (s.Length - s.Replace(word, "").Length) / word.Length;
4.     }
5.  

And call it like

Code (csharp):

1.  
2. int wordCount = YourClass.WordCount(source, " source");
3.  

 

Ok, thanks man.
