  LIST - How to form a list in the given example

  Jul 21, 2017 07:05 AM|gani7787|LINK

  Hi,

  I want to form below output after executing my code.

  Output should come as mentioned below format as list <string> RESULTVALUE .

  list <string> RESULTVALUE 

  [0]Sub1 = 400

  [1]Sub2 = 500

  i'm struggling to form the loop

  below is my code

    List<string> RESULTVALUE  = new List<string>();
          string str1 = "Sub1#Sub2";
          string[] words1 = str1.Split('#');   
          string str2 = "400,500";
          string[] words2 = str2.Split(',');
          double value = 0;
  
          for (int i = 0; i < words1.Length; i++) 
          {
              for (int j = 0; j < words2.Length; i++) 
              {
  
                  value = Convert.ToDouble(words2[j]);  ????????
              }
  
              RESULTVALUE.Add(words1[i] + "=" + value); ????????
              
          }

  Final output is :

  list <string> RESULTVALUE 

  [0]Sub1 = 400

  [1]Sub2 = 500

  where we need to change the code..?

  Hi gani7787,

  Does the length of words1 always equal the length of words2?

  If so you could try below code:

              List<string> RESULTVALUE = new List<string>();
              string str1 = "Sub1#Sub2";
              string[] words1 = str1.Split('#');
              string str2 = "400,500";
              string[] words2 = str2.Split(',');
               double value = 0;
  
              for (int i = 0; i < words1.Length; i++)
              {  
                  value = Convert.ToDouble(words2[i]);              
  
                  RESULTVALUE.Add(words1[i] + "=" + value);
               }

  Best Regards,

  Billy

  Hi 

  gani7787,

  If I am not wrong then what I understood is, you want to parse two lists and want to concatenate into one with pairing values from both the list. To achieve this you can you Dictionary as below. Also assuming length of both of the lists will be same. Or you need to apply extra validation.

  string str1 = "Sub1#Sub2";
  string[] words1 = str1.Split('#');
  string str2 = "400,500";
  string[] words2 = str2.Split(',');	
  	
  Dictionary<string, string> RESULTVALUE = new Dictionary<string, string>();
  for(int i = 0 ; i < words1.Length ; i++)
  {
  	RESULTVALUE.Add(words1[i], words2[i]);
  }
  	
  foreach (var pair in RESULTVALUE)
  {
        Console.WriteLine("{0}, {1}", pair.Key, pair.Value);
  }

  Output:

  Sub1, 400
  Sub2, 500

  Or with a bit less code ....

  string str1 = "Sub1#Sub2";
  string str2 = "400,500";
  var RESULTVALUE = Enumerable.Zip(str1.Split('#'), str2.Split(','), (first, second) => $"{first}={second}");
