First and FirstOrDefault LINQ

Comment

var list1 = new List<int>() { 1, 2, 3, 4, 5, 6, 7, 8 };
var result = list1.First();
// if list is empty then the exception is fire
Console.WriteLine(result); // 1

//So to avoid exception firing, we use FirstOrDefault, which returns the default value of the datatype.var list2 = new List<int>();
var list2 = new List<int>(); // empty list
var result2 = list2.FirstOrDefault();
Console.WriteLine(result2); // 0
