c# - Merge sorting days of the week -

i have object array (stockarray) has string property stores days of week. have done merge sort algorithm sort these in order of days of week , not in alphabetical order. have done converting days numbers , storing these in double[] array:

string[] daysarray = new string[5] { "monday", "tuesday", "wednesday", "thursday", "friday" };  (int = 0; < stockarray.length; i++) //stockarray object array {     (int j = 0; j < daysarray.length; j++)     {          if (daysarray[j] == stockarray[i].day)           {               sortarray[i] = j;               break;          }     } } 

i perform merge sort , want output values, have been sorted, days of week format (i.e. "monday", "tuesday" etc), , match correct days of week other properties in object array (stockarray)

string day = ""; int m = 0;  while (m < stockarray.length) {     foreach (double in sortarray)     {         if (a == 0)                                  day = "monday";                else if (a == 1)            day = "tuesday";         else if (a == 2)            day = "wednesday";         else if (a == 3)            day = "thursday";         else if (a == 4)            day = "friday";          if (day == stockarray[m].day)         {            console.writeline(stockarray[m].date);            console.writeline(stockarray[m].day);            console.writeline(stockarray[m].open);            console.writeline(stockarray[m].close);            console.writeline(stockarray[m].difference);            console.writeline(stockarray[m].volume);            console.writeline("");          }         m++;                            }  }                  console.readline(); 

the problem code outputs 31 out of 144 days in stockarray. have checked merge sort algorithm code , seems working error seems in while , foreach loop. doesn't crash - doesn't output elements. if me find error in code appreciated.

try solution:

class stock {     public int value;     public string day; }  dictionary<string, int> dic = new dictionary<string, int>(); dic.add("monday", 0); dic.add("tuesday", 1); dic.add("wednesday", 2); dic.add("thursday", 3); dic.add("friday", 4);  var stocks = new stock[]     {         new stock { day = "tuesday", value= 10 },         new stock { day = "monday", value= 5 },     };  // result here var result = stocks.orderby(f => dic[f.day]).toarray(); foreach (var item in result) {     console.writeline(item.day);     console.writeline(item.value); }
