Write a C# Sharp program to concatenate three objects, objects with a variable and a 3-element object array.

Sample Solution:-

C# Sharp Code:

using System;

class Example34
{
    public static void Main()
    {
        int i = -123;
        Object o = i; // Assigning an integer value to an object reference.
        Object[] objs = new Object[] { -123, -456, -789 }; // Creating an object array.

        // Concatenate different combinations of objects and display the results.
        Console.WriteLine("Concatenate 1, 2, and 3 objects:");
        Console.WriteLine("1) {0}", String.Concat(o)); // Concatenating a single object.
        Console.WriteLine("2) {0}", String.Concat(o, o)); // Concatenating two objects.
        Console.WriteLine("3) {0}", String.Concat(o, o, o)); // Concatenating three objects.

        Console.WriteLine("\nConcatenate 4 objects and a variable length parameter list:");
        Console.WriteLine("4) {0}", String.Concat(o, o, o, o)); // Concatenating four objects.
        Console.WriteLine("5) {0}", String.Concat(o, o, o, o, o)); // Concatenating five objects.

        Console.WriteLine("\nConcatenate a 3-element object array:");
        Console.WriteLine("6) {0}", String.Concat(objs)); // Concatenating objects from an array.
    }
}

Sample Output:

Concatenate 1, 2, and 3 objects:                                                                              
1) -123                                                                                                       
2) -123-123                                                                                                   
3) -123-123-123                                                                                               
                                                                                                              
Concatenate 4 objects and a variable length parameter list:                                                   
4) -123-123-123-123                                                                                           
5) -123-123-123-123-123                                                                                       
                                                                                                              
Concatenate a 3-element object array:                                                                         
6) -123-456-789
