C# Sharp Exercises: Concatenate three objects, objects with a variable and 3-element object array

C# Sharp String: Exercise-34 with Solution

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

Sample Solution:-

C# Sharp Code:

using System;

class Example34
{
    public static void Main() {
    int i = -123;
    Object o = i;
    Object[] objs = new Object[] {-123, -456, -789};

    Console.WriteLine("Concatenate 1, 2, and 3 objects:");
    Console.WriteLine("1) {0}", String.Concat(o));
    Console.WriteLine("2) {0}", String.Concat(o, o));
    Console.WriteLine("3) {0}", String.Concat(o, o, o));

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

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

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
