c# - Split string so that all + datain to one list and - data in to another -


i having string follows separate in such way should give me + data in 1 list , - in other list.

string inputstr = "dim h + qut of pip dim - dim l + xyz - abc";

my expected follows

string[] positives = "dim h qut of pip dim xyz" string[] negatives = "dim l abc"

and when match original string know whether + or - when match found.

public bool findmatchesinstringarray(string markup, string[] strarray, out string matchstring) {     bool flag = false;     matchstring = string.empty;     (int = 0; < strarray.length; i++)     {         match match = regex.match(markup, strarray[i].trim(), regexoptions.ignorecase);         if (match.success)         {             flag = true;             matchstring = match.value;         }     }     return flag; }

here in markup send dim h or other when match found should give me + dim h or -abc.

here non regex solution:

static list<string> listofpositive = new list<string>(); static list<string> listofnegative = new list<string>(); static bool initialpositivecheck = false; static void main(string[] args) {     string inputstr = "dim h + qut of pip dim - dim l + xyz - abc";     addtolist(inputstr);     listofpositive.reverse();     listofnegative.reverse();     console.writeline(string.join("", listofpositive));     console.writeline(string.join("", listofnegative));          }  static void addtolist(string newstring) {     if (!(newstring.trim().startswith("+")) && !initialpositivecheck)     {        newstring = "+ " + newstring;        initialpositivecheck = true;     }      int indexofplus = newstring.lastindexof("+");     int indexofminus = newstring.lastindexof("-");      string str = "";     if (indexofminus == -1 && indexofplus == -1)         return;      if (indexofplus < indexofminus)     {        str = newstring.substring(indexofminus + 1);        listofnegative.add(str);        str = newstring.remove(indexofminus);        addtolist(str);     }     else     {        str = newstring.substring(indexofplus + 1);        listofpositive.add(str);        str = newstring.remove(indexofplus);        addtolist(str);     }  }

link .net fiddle

output:

 dim h  qut of pip dim  xyz   dim l  abc

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
