16)How to remove duplicates in array list

   Remove duplicate values through List Contain method
public string[] RemoveDuplicates(string[] inputArray)
{
    List<string> distinctArray = new List<string>();
    foreach (string element in inputArray)
    {
        if (!distinctArray.Contains(element))
            distinctArray.Add(element);
    }

    return distinctArray.ToArray<string>();
}

Delete Duplicate elements through ArrayList Contain method
public string[] RemoveDuplicates(string[] inputArray)
{
    System.Collections.ArrayList distinctArray = new System.Collections.ArrayList();

    foreach (string element in inputArray)
    {
        if (!distinctArray.Contains(element))
            distinctArray.Add(element);
    }

    return (string[])distinctArray.ToArray(typeof(string));

}
------------------------------------
Remove Duplicate number / record of array through Linq Distinct method
public string[] RemoveDuplicates(string[] inputArray)
{
    return inputArray.Distinct().ToArray<string>();
}

public int[] RemoveDuplicates(int[] inputArray)
{
    return inputArray.Distinct().ToArray<int>();

}

Removing Duplicate entries through traditional for loop
public string[] RemoveDuplicates(string[] inputArray)
{

    int length = inputArray.Length;
    for (int i = 0; i < length; i++)
    {
        for (int j = (i + 1); j < length; )
        {
            if (inputArray[i] == inputArray[j])
            {
                for (int k = j; k < length - 1; k++)
                    inputArray[k] = inputArray[k + 1];
                length--;
            }
            else
                j++;
        }
    }

    string[] distinctArray = new string[length];
    for (int i = 0; i < length; i++)
        distinctArray[i] = inputArray[i];

    return distinctArray;

}

Calling of RemoveDuplicates method -

string[] inputArray = { "array", "array", "distinct", "elememnt", "remove", "distinct", "delete", "delete", "delete" };
string[] distinctArray = RemoveDuplicates(inputArray);
