Learning Methods and Collections

Methods

A method is a block of code that implements some action. ToUpper() is a method you can invoke on a string, like the name variable. It will return the same string, converted to uppercase.

var name ="BUILD";
Console.WriteLine($"Hello {name.ToUpper()}!");

Collections

Collections hold multiple values of the same type.

Replace the name variable with a names variable that has a list of names. Then use a foreach loop to iterate over all the names and say hello to each person.

 var names = new List<string> { "Rain", "Sage", "Lee" };
 foreach (var name in names)
     {
          Console.WriteLine($"Hello {name.ToUpper()}!");
     }
