C#: Create a new list from a given list of strings where strings will be in upper case in new string
Convert Strings to Uppercase
Write a C# Sharp program to create a list from a given list of strings. Strings will be in upper case in the new string.
Visual Presentation:

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
