c# - Unable to find intersection of two array -

I have an array int [] com with two values ​​being 0 and 1 (in the initial step )).

I string [] arr = new string [100]; Element defines another array as

arr element:

  arr [0] = {4, 8,10,11,12,14} arr [1] = {1,2,3,4,8,12, 14} .. arr [6] = some   
 I I want to search the int [0] and the int [1] intersection, so I wrote the code in this form:  
  foreach (int value1 in int intro) {// show logic}   
 Here I should get value 1 as 4,8, but I'm getting 52,44 as value 1.  
 What am I doing, what's wrong with it?   
 
 
 OK, what are you doing, you do not have any string array that is not an ARRAGE If you do this  
  arr [0] = "4,8,10,11,12,14"; Advent [1] = "1,2,3,4,8,12,14"; Var intersection = ARR [0]. Cutting (ARR [1]); As a result, you will find this list of characters as  arr [0]  and  arr [1]   '4', ',', '8' , '1', '2'  which corresponds to the integer values ​​ 52 44 56 49 50 , which is actually what you are getting.  
 You have  int [,] arr = new int [100,100];  or better  list & lt; List & lt; Int & gt; Instead of strings, declare an integer matrix. & Gt; . You can not use an integer like strings, at least not in this context.  
  list & lt; List & lt; Int & gt; & Gt; Arr = new list & lt; List & lt; Int & gt; & Gt; (); Arr.Add (new list & lt; int & gt; {4,8,10,11,12,14}); Arr.Add (new list & lt; int & gt; {1,2,3,4,8,12,14}); Var intersection = ARR [0]. Cutting (ARR [1]);   
 But if you do not trust me, and want to make sure that you do not have any sense in your previous code, then replace  foreach  loop and See what's happening:  
  foreach (punching in cell value 1) {// display logic}   
 In addition, you need to do this Not:  
  return to zero = convert toInt32 (com [0]. Ostring ()); Int convert a =. ToInt32 (com [1]. Ostring ());   
 You can change it like something:  
  int zero = com [0]; Int one = com [1];   
 But still it is useless because you can:  
  arr [com] [0]] arr [com [1]]
