根据输入的列表C＃动态创建具有属性的对象

Question

I have a method that takes in two arrays of integers as parameters. I want to dynamically create objects based on the input. So if user puts in [2,3] and [4,3,2], I want to create 3 new Objects ( Friend2, Friend3 , Friend4). I have 2 issues I am stuck with:

• Dynamically creating multiple objects with different names based on list items

• Iterating through two lists and selecting only distinct values of both lists.

    static int maxTokens( int[] friends_from, int[] friends_to){ **-- Need Code Here to iterate through both arrays and create distinct objects** foreach (var Friend in friends_from and friends_To) { Friend intFriend[i] = new Friend(); } } 

  Is there a way to use Linq to (If not what is the best way to accomplish this?):

• Save myself from iterating through two lists adding both of them to a third list and selecting distinct

• dynamically create object with distinct Name based on listItem

Answer 1

You can use union operation to get an array of distinct values like below and then create your object as required

 static int maxTokens( int[] friends_from, int[] friends_to)
 {
     var uniqueFriends = friends_from.Union(friends_to).ToArray();

     foreach (var Friend in  uniqueFriends)
     {
        // add your logic for creating instance
     }
  }
