C# Sharp: Basic Algorithm Exercises - Create a new list from a given list of strings where strings will be in upper case in new string.

Sample Solution:

C# Sharp Code:

using System; // Importing the System namespace for basic functionality
using System.Collections.Generic; // Importing the namespace for working with collections
using System.Linq; // Importing the namespace for LINQ operations

namespace exercises // Defining a namespace called 'exercises'
{
   class Program // Defining a class named 'Program'
   {
       static void Main(string[] args) // The entry point of the program
       {         
           // Calling the 'test' method with a new list of strings as input
           List<string> mylist = test(new List<string>(new string[] { "Abc", "cdef", "js" , "php" }));

           // Displaying elements of 'mylist' in the console
           foreach(var i in mylist)
           {
               Console.Write(i.ToString()+" "); // Output each element followed by a space
           }     
       }                  

       // Method that takes a List of strings and converts each string to uppercase
       public static List<string> test(List<string> str)
       {
           // Using LINQ to convert each string in 'str' list to uppercase
           IEnumerable<string> s = str.Select(x => x.ToUpper());

           // Converting the IEnumerable 's' to a new List and returning it
           return s.ToList();
       }    
    } 
}

Sample Output:

ABC CDEF JS PHP
