3int[] MyArray = { 0, 0, 1, 2, 3, 3, 4}; int[] MyDistinctArray = MyArray.Distinct().ToArray(); Will give you MyDistinctArray = { 0, 1, 2, 3, 4}DbxD– DbxD2015-06-22 04:34:17 +00:00Commented Jun 22, 2015 at 4:34

You could use the .Distinct() extension method.
var collectionWithDistinctElements = oldArray.Distinct().ToArray();

Using Distinct() function:
var distinctArray = myArray.Distinct().ToArray();

Your dinstincts are correct :)
Use the Distinct method in LINQ.
See http://msdn.microsoft.com/en-us/library/bb348436.aspx
List<int> ages = new List<int> { 21, 46, 46, 55, 17, 21, 55, 55 };
IEnumerable<int> distinctAges = ages.Distinct();
Console.WriteLine("Distinct ages:");
foreach (int age in distinctAges)
{
Console.WriteLine(age);
}
/*
This code produces the following output:
Distinct ages:
21
46
55
17
*/

Distinct should suffice your problem, but if you are doing this on custom object you will need to implement IEquatable<T> and will need to override GetHashCode() method to make it work.
