Try this. Tested working.

using System;

namespace ConsoleApplication
{
    internal class Program
    {
        private static void Main(string[] args)
        {
            char[] letter = new char[26]
            {
                'A', 'B', 'C', 'D', 'E', 'F', 'G', 'H', 'I', 'J', 'K', 'L', 'M', 'N', 'O', 'P', 'Q', 'R', 'S', 'T', 'U',
                'V', 'W', 'X', 'Y', 'Z'
            };
            int letter_number = 0;

            //array of strings
            string[] diamond = new string[52];
            //get the letter
            Console.WriteLine("User enters a Letter between A and Z ");
            char user_letter = Console.ReadKey().KeyChar;
            Console.WriteLine("");
            //search for letter number in the array letter
            for (int i = 0; i < letter.Length; i++)
            {
                if (letter[i] == user_letter)
                {
                    letter_number = i;
                    break;
                }
            }

            //construct diamond 

            for (int i = 0; i <= letter_number; i++)
            {
                //add initial spaces
                for (int j = 0; j < letter_number - i; j++)
                {
                    diamond[i] += " ";
                }

                //add letter (first time)
                diamond[i] += letter[i];

                //add space between letters
                if (letter[i] != 'A')
                {
                    for (int j = 0; j < 2*i - 1; j++)
                    {
                        diamond[i] += " ";
                    }
                    //add letter (second time)
                    diamond[i] += letter[i];
                }
                // Draw the first part of the diamond as it's composing.
                Console.WriteLine(diamond[i]);
            }

            for (int i = letter_number - 1; i >= 0; i--)
            {
                // Draw the second part of the diamond
                // Writing the diamondArray in reverse order.
                Console.WriteLine(diamond[i]);
            }

            // Mark a pause
            Console.ReadKey();
        }
    }
}

Output : 

User enters a Letter between A and Z
K
          A
         B B
        C   C
       D     D
      E       E
     F         F
    G           G

  I               I
 J                 J
K                   K

  I               I
   H             H
    G           G
     F         F
