LINQ OPERATOR — WHERE

C# Concepts | LINQ

WHERE OPERATION — Allows us to sort an existing collection and create a new collection based on some condition
→ returns a IEnumerable

OBJECTIVE:
Sort through the collection names[] and create a separate collection with each name that is longer than 4 characters. Then print those values.

public string[] names = {"jon","jon","julie","jessie","mark","matt","jordan"};

void Start()
{
  var result = names.where(n => n.Length > 5); //STEP ONE

  foreach(var name in result) //STEP TWO
  {
    Debug.Log("Name: " + name);
  }
}

STEP ONE — Use the where operator to return an IEnumerable with a collection of names that are longer than 4 characters
→ Can be read as: where variable(n) in array(names) meets condition(longer than 4 characters)
→ All elements that match the condition are then placed within our IEnumerable Variable result

STEP TWO — Prints each name in the new IEnumarable Collection

LINQ OPERATIONS

ANY OPERATION
Filters through a collection to determine if each element in the collection satisfy a specified condition.

CONTAINS OPERATOR
Similar to the Any Operator in that is also makes sure something exists in a array/list.

DISTINCT OPERATION
Filters through an array/list to remove any duplicate values.

OrderByDescending OPERATOR
Sorts values in a collection ina descending order
