Question

I made a static function that returns me an ArrayList of objects:

 allThread =(ArrayList) AllQuestionsPresented.GetAllThreads();

Now the objects have properties that i want to get out. But I noticed that i cant type allThreads.Name…or
allThreads[“Name”] , or allThreads[1], it wont give me the object itself. Cause intellisense doesnt recognize it..

Here is what I am trying to do..:

That function is in one class:

    public static ICollection GetAllThreads()
{
    ArrayList allThreads = new ArrayList();
    string findUserID = "SELECT UserID FROM Users";
    string myConnectionString = AllQuestionsPresented.connectionString;

    using (SqlConnection myConnection = new SqlConnection(myConnectionString))
    {
        SqlCommand sqlCommand = new SqlCommand(findUserID, myConnection);
        SqlDataReader reader = sqlCommand.ExecuteReader();
        while (reader.Read())
        {
            AllQuestionsPresented allQ = new AllQuestionsPresented((Guid)reader["UserID"]);
            allThreads.Add(allQ);
        }
    }
    return allThreads;
}

That is some code from another function in another class:

    forumsPages = new Dictionary<int, List<DisplayAllQuestionsTable>>();
    allThread =(ArrayList) AllQuestionsPresented.GetAllThreads();//I want to convert the ICollection


    for (int i = 0; i < 20; i++)
    {
        threads.Add(new DisplayAllQuestionsTable(allThread[i].//And use it here. I want an object to be returned..same object that was stored in the ArrayList in the static function

    }

USE A List:

 public static List<AllQuestionsPresented> GetAllThreads()
{
    List<AllQuestionsPresented> allThreads = new List<AllQuestionsPresented>();
    string findUserID = "SELECT UserID FROM Users";
    string myConnectionString = AllQuestionsPresented.connectionString;

using (SqlConnection myConnection = new SqlConnection(myConnectionString))
    {
        SqlCommand sqlCommand = new SqlCommand(findUserID, myConnection);
        SqlDataReader reader = sqlCommand.ExecuteReader();
        while (reader.Read())
        {
            AllQuestionsPresented allQ = new AllQuestionsPresented((Guid)reader["UserID"]);
            allThreads.Add(allQ);
        }
    }
    return allThreads;
}
