Please try this, I hope it will work:

public string[] AutoCompleteCustomSource
{
    get
    {
        List<string> lStringList = new List<string>();
        foreach (string lval in this.mEkaTextBox.AutoCompleteCustomSource)
        {
            lStringList.Add(lval);
        }
        return lStringList.ToArray();
    }
    set
    {
        txtLocl.AutoCompleteCustomSource.AddRange(value);
    }
}
