Remove Duplicates and Sort an Integer Array without LINQ in ASP.Net

Using the link http://www.softwareandfinance.com/CSharp/Unique_Elements_Arrays.html

You can do as following

string randomno = "1,2,1,5,5,5,1,2,2,2,1,5,5,2,1,1,5,2";
        string[] s1 = randomno.Split(',');
        int[] x = new int[s1.Length];
        for (int i = 0; i < s1.Length; i++)
        {
            x[i] = int.Parse(s1[i]);
        }
x = Find_Unique_Elements(x);
x = BubbleSort(x);
randomno = "";
        foreach (int i in x)
        {
            randomno += i.ToString() + ",";
        }
        string final = randomno.Substring(0, randomno.Length - 1);
