c# - Beginner level - saving str to an Array -


hey guys need help.

i tried while understand how arrays work , using loop search inside of them , seems working.

my first question is, how can add array inside while loop in program?

the functionality follows: add string array, print out whole array, search inside of array

any appreciated.

static void main(string[] args)     {         bool isrunning = true;         int menyval;         int allitem = 5;         string[] rygga = new string[allitem];         rygga[0] = "1";         rygga[1] = "2";         rygga[2] = "3";         rygga[3] = "";         rygga[4] = "";           while (isrunning)          {             console.writeline("\n\tvälkommen till ryggsäcken! vänligen välj ett av dessa val med en siffra.");              console.writeline("\t[1]lägg till föremål / add item");             console.writeline("\t[2]skriv ut innehållet/ print out all");             console.writeline("\t[3]sök ryggsäcken/ search in array");             console.write("\tvälj en siffra: / choose number ");             int menyval = convert.toint32(int32.tryparse(console.readline(), out menyval));              //använda menyvalet med switch              switch (menyval)             {                  case 1:                     {                          //spara användarens föremål                         console.write("skriv vad föremålet heter för att spara det ryggsäcken: ");                          break;                     }                 case 2:                     {                         //visa vad som ligger sparat ryggsäcken                              break;                     }                 case 3:                     {                         console.writeline("skriv in ett sökord : ");                           string sökord = console.readline();                         try                         {                             (int = 0; < rygga.length; i++)                             {                                 if (rygga[i] == sökord)                                     console.writeline(rygga[i]);                             }                              console.readline();                          }                         catch                         {                              console.writeline("inget hittades! ");                          }                         break;                     }                 default:                     {                          // med uppmaningen att skriva 0 - 4                          console.writeline("du måste välja en siffra mellan 0-4!");                            break;                     }             }         }     }

your array can contain 5 (allitem) entries. search next empty entry in array with:

int emptyindex = -1; foreach(string s in rygga) {   if(s == "")   {     emptyindex = array.indexof(rygga,s);     break;   } }  if(emptyindex >= 0) {   rygga[emptyindex] = //userinput; } else {  //inform there no more space fill  //eventually can overwrite index 0 then. depends on suits better }

if need add unknown amount of times, array not way go. better use

list<string> rygga = new list<string>(); rygga.add(//userinput);

for have import

using system.collections.generic;

edit:

in both cases (list , array) can go:

foreach(string s in rygga) {   console.writeline(s); }

Add a dynamic header in angular 2 http provider -

i have http interceptor built via tutorial https://scotch.io/@kashyapmukkamala/using-http-interceptor-with-angular2 the problem need have dynamic header changes automatically once changes 'mode' in app. service able tell interceptor change header, or have interceptor pull header (which string)from service each request. able throwing away patch method, call http.patch('new header string') set header string. call in service controls 'mode' setting. wondering if there way interceptor pull recent value service each request or if can add method http provider via interceptor? i've tried call service in interceptor each request returns undefined. because creating new instance of service or copying value before service fired , loaded/changed data. i don't want pass header string every http provider call because defeats purpose of having interceptor, id able set once changes or have provider fetch service before makes request. tl;dr : need add autom
