//Declare Array
int[] array = new int[] { 3, 1, 4, 5, 2 };
// Sort Method used Asending Order
Array.Sort
( array );
// reverse Method used Decenting Order
Array.Reverse( array );
1. Remove duplicate elements from an array
static void Main(string[] args) {
var ints = new[] { 1, 2, 3, 4, 4, 4, 5, 6, 6, 6, 5, 3, 3 };
var no_dupes = ints.Distinct(); //That's it. Magic.
foreach (int i in no_dupes)
Console.Write(i + ","); //1,2,3,4,5,6,
Console.ReadKey();
}
2. Suppose you want to eliminate duplicate elements from the array
int[] source = { 7, 4, 1, 3, 9, 8, 6, 7, 2, 1, 8, 15, 8, 23}
and sort the elements in descending order using LINQ in Asp.Net framework 4.0. Which of the following statements can you use?
var result = (from s in source orderby s descending select s).Distinct();
3.
Boxing is an explicit conversion from the value type to a type object
Unboxing is an explicit conversion from the type object to a value type
int i = 123; // A value type
object box = i; // Boxing
int j = (int)box; // Unboxing
4.
string[] a = {"a","b","a","c","b","b","c","a"};
var b = a.Distinct().ToArray();
Output
string[]b = {"a","b","c"}
