Hi,

Use the Distinct extension method:

C#

int[] array = new int[7] { 7, 8, 1, 9, 10, 7, 1 };
array = array.Distinct().ToArray();

Hope this helps.

You can achive you aim with help of LINQ:

C#

string[] testArray=new string [3]{ "Data","Data ","One"};
var arrayWithout=testArray.Distinct().ToArray();
