c# - Splitting a string seems not to work -

i have problems reading file (textasset) line line , getting results!

here file trying read:

author comment  info      1  x   arg  0001       0.581   2.180   1.470 info      2  x   arg  0001       1.400   0.974   1.724 info      3  x   arg  0001       2.553   0.934   0.751 info      4  x   arg  0001       3.650   0.494   1.053 info      5  x   arg  0001       1.188   3.073   1.532 info      6  x   arg  0001       2.312   1.415  -0.466 info      7  x   arg  0001      -0.232   2.249   2.180 end 

here code using:

//read file string[] line = file.text.split("\n"[0]);  for(int = 0 ; < line.length ; i++) {     if(line[i].contains("info"))     {         //to replace spaces single underscore "_" (it works fine)         string l = regex.replace(line[i]," {2,}","_");         //in debug.log correct results        //for example "info_1_x_arg_0001_0.581_2.180_1.470"        debug.log(l);        string[] subline =  regex.split(l,"_");        //only first "info" line correct results (info,1,x,arg,0001,0.581,2.180,1.470)        //for other "info" lines incomplete results (first,fourth , fifth element not put substrings        //like dissapeard!        foreach(string s in subline){debug.log(s);}     } } 

explanation:

i first split text lines (works fine),then read lines contain info

i loop lines contain info , replace spaces underscore _ (this works fine)

i split lines contain info substrings based on underscore _

when print out lines first line info seems have substrings every next line not splitted correctly (first part info omitted third string)

it seems unreliable. way go these things? appreciated! should simple, doing wrong?

edit:

something wrong code (it should simple, not work)

here updated code (i made list<string> list = new list<string>() , copied substrings. use unity3d list contents show in inspector. shocked when extracted substrings simple

foreach(string s in list)  debug.log(s); 

was indeed missing values. trying different things , code:

for(int x = 0; x < list.count ; x++) {   debug.log("list: " + x.tostring() + " " + list[x].tostring()); } 

shows contents of list properly, code (note removed x.tostring()) missing elements in list. not want read them!

for(int x = 0; x < list.count ; x++)   debug.log("list: " + list[x].tostring()); 

so not sure going on here?!

there problems

1>the contains method using case sensitive i.e info != info

you should use

line[i].tolower().contains("info") 

2>is text separated space.it may separated tabs.you better off with

regex.replace(line[i]," {2,}|\t+","_"); //this replace 1 many tabs or 2 or more space
