how to read a file??

Hi everybody,

i've search a way to read a file and i've find that :

Code (csharp):

1.  
2. function Read_File (filename : String, tab : Array) {
3.  
4.     var SR : StreamReader;
5.     var S : String;
6.     var i = 0.0;
7.     SR=File.OpenText(filename);
8.     S=SR.ReadLine();
9.     while(S!=null)
10.     {
11.     tab[i] = S;
12.     i++;
13.     S=SR.ReadLine();
14.     }
15.     SR.Close();
16.  
17. }
18.  

the file i want to read contains this :

Code (csharp):

1.  
2. 1234
3. 5678
4.  

then i want to compare the 2 numbers but the function "Read_File" returns a string

so i've tried to do this

the variable tab contains: tab[0] = "1234" and tab[1] = "5678"
so tab[0][0] = "1";

Code (csharp):

1.  
2. var trial = 0.0;
3. if (tab[0][0] == "1"){
4. trial = 1.0;
5. }
6. else{
7. print("error");
8. }
9.  

and that always prints "error" and i don't understand why...

i've tried another way, i've thought it could be possiblr*e to convert each character from the file to its ASCII code but unity doesn't seem to recognize the function "charCodeAt()"

i've tried this :

Code (csharp):

1.  
2. print(tab[0].charCodeAt(1));
3.  

and the result is :

and to finish i've tried to convert the character with "parseInt" but without results... :

Code (csharp):

1.  
2. var code = 0;
3. print(parseInt(tab[0][1]));
4.  

and the result :

can someboy help me?? (with one of the ideas i had or with another)

thanks in advance

 

i think you need to parse string value to float:

Code (csharp):

1.  
2. function Read_File (filename : String, tab : Array) {
3.  
4.    var SR : StreamReader;
5.     var S : String;
6.    var i = 0.0;
7.     SR=File.OpenText(filename);
8.     S=SR.ReadLine();
9.     while(S!=null)
10.     {
11.    tab[i] =  float.Parse(S); <------------
12.    i++;
13.     S=SR.ReadLine();
14.     }
15.     SR.Close();
16.  
17. }
18.  

 

ok i will try
thanks for your answer
