    In my application i have written a function that create the array of the codes from database. Just like that:

    [code title=””]
    codes[0] = “ERQ”
    codes[0] = “RTQ”
    codes[0] = “POQ”
    codes[0] = “ERQ”
    codes[0] = “POQ”
    codes[0] = “TRQ”
    [/code]

    After that i need all values but in one case i need only distinct values.
    This time i am creating the HashSet object to remove the duplicates values. Can i use the LINQ, of yes than what will be the linq query to remove duplicates?

    just use the:

    [code title=”C#”]int[] q = s.Distinct().ToArray();[/code]

    You can also use the LIST object to remove the duplicates:
