You can use the string.Join() method to concatenate the elements of an array into a single string, with each element separated by a specified delimiter, such as a comma, semi-colon, hyphen, etc. 

Here's how you can do it:

using System;
namespace ConsoleApp1
{
    class Program
    {
        static void Main(string[] args)
        {
            // Sample array
            string[] array = { "apple", "banana", "orange", "grape" };

            // Joining array elements with a comma separator
            string result = string.Join(", ", array);

            // Displaying the result
            Console.WriteLine(result);
            Console.ReadLine();
        }
    }
}

string.Join() takes two parameters: the separator (", " in this case) and the array of strings to join. It returns a single string containing all the elements of the array separated by the specified separator.

Output -

apple, banana, orange, grape
