-

i need call array following program working, can't figure out. i'm not sure or isn't working, because can't list box populate. following code. 

using system.io;  namespace test_your_knowledge__game { public partial class form1 : form {      public form1()     {         initializecomponent();     }         string questionone;         string questiontwo;         string questionthree;                           string firstquestion = ("who silk worm?");         string secondquestion = ("what sapience mean?");         string thirdquestion = ("what tainou?");         string firstanswer = ("onycho");         string secondanswer = ("wisdom");         string thirdanswer = ("a wolf");         int count = 0;       private void listbox1_selectedindexchanged(object sender, eventargs e)     {      }     private void playbutton_click(object sender, eventargs e)   {        string name;       string email;         name = nametextbox.text;       email = emailtextbox.text;        streamwriter outputfile;       outputfile = file.createtext("submission_list.txt");        outputfile.writeline(name);       outputfile.writeline(email);       outputfile.writeline(count);        outputfile.close();    }     private void myarray(string[] strarray, string value)     {          bool found = false;         int index = 0;         int position = -1;          while (!found && index < strarray.length)              if (strarray[index] == value)             {                 found = true;                 position = index;                 index++;             }          string[] questiononearray = { "1) beebo", "2) bael", "3) onycho", "4) ilion" };         string[] questiontwoarray = { "1) beauty", "2) cursed", "3) properity", "4) wisdom" };         string[] questionthreearray = { "1) imp", "2) wolf", "3) trow", "4) elf" };          foreach (string length in strarray)          {             try             {                 if (questiononearray[index] != firstanswer)                 {                      questionone = (firstquestion + "" + questiononearray);                     listbox1.items.add(questionone.tostring());                     found = false;                 }                 else                 {                     found = true;                     count++;                 }                   {                     if (questiontwoarray[index] != secondanswer)                     {                         questiontwo = (secondquestion + "" + questiontwoarray);                         listbox1.items.add(questiontwo.tostring());                         found = false;                      }                     else                     {                         found = true;                         count++;                     }                      {                         if (questionthreearray[index] != thirdanswer)                         {                             questionthree = (thirdquestion + "" + questionthreearray);                             listbox1.items.add(questionthree.tostring());                             found = false;                          }                         else                         {                             found = true;                             count++;                         }                      }                 }             }             catch (exception)  { } } } }

all have use datasource property

public partial class form1 : form {     public form1()     {         initializecomponent();     }      protected override void onload(eventargs e)     {         base.onload(e);          string[] questions=new string[] {             "who silk worm?",             "what sapience mean?",             "what tainou?"         };          listbox1.datasource=questions;     } }

scr

alternatively can read file

list<string> questions=new list<string>(); var fs=file.opentext("<path file questions here>"); while (fs.endofstream) {     questions.add(fs.readline()); } fs.close();  listbox1.datasource=questions;
