Two-Dimensional Array

[Lucent2418]

I am trying to return a two-dimensional array with data but am having some problems retreving the data. Can someone guide me what I should change in this code?

Thanks

public ArrayList getData()
{
	ArrayList data = new ArrayList();
	ArrayList myList1 = new ArrayList();
	ArrayList myList2 = new ArrayList();
	int i;
        
	for(i=0; i<5; i++)
	{
		i++;
		myList1.Add("San");
	}

	for(i=0; i<5; i++)
	{
		i++;
		myList2.Add("Diego");
	}

	data.Add(myList1);
	data.Add(myList2);
        
return data;

method for retreving the data

ArrayList Data = new ArrayList();
DatabaseAccessLayer DAL = new DatabaseAccessLayer();
data = DAL.getData;

for(int i=0; i<data.Count; i++)
{
	Data = ((ArrayList)(data[i]));
	Console.Write((string)(Data[0]));
	Console.Write((string)(Data[1]));
}

You are itterating your counter (i++) two times in each loop in your populating thing.

Otherwise I don't see why it wouldn't work

	data.Add(myList1);
	data.Add(myList2);
        
return data;

method for retreving the data

ArrayList Data = new ArrayList();
DatabaseAccessLayer DAL = new DatabaseAccessLayer();
data = DAL.getData;

for(int i=0; i<data.Count; i++)
{
	Data = ((ArrayList)(data[i]));
	Console.Write((string)(Data[0]));
	Console.Write((string)(Data[1]));
}

Note that a two-dim array is not the same as an arraylist of arraylists.
You should also consider using a typed collection.

Thanks. I've rearranged the code and it now returns data. This is an arraylist made up of several arraylists.

How could I organize the data to return in this manner:

A1x
B2x
C3x
and so on.

ArrayList data;
ArrayList Data = new ArrayList();
DatabaseAccessLayer DAL = new DatabaseAccessLayer();
data = DAL.getData();
 
for(int i=0; i<data.Count; i++)
{
	Data = ((ArrayList)(data[i]));
	Console.WriteLine((string)(Data[0]));
	Console.WriteLine((string)(Data[1]));
	Console.WriteLine((string)(Data[2]));
	Console.WriteLine((string)(Data[3]));
	Console.WriteLine((string)(Data[4]));
	Console.WriteLine((string)(Data[5]));
	Console.WriteLine((string)(Data[6]));
	Console.WriteLine((string)(Data[7]));
}

Sample data

public ArrayList getData()
{
	ArrayList data = new ArrayList();

	ArrayList myList1 = new ArrayList();
	ArrayList myList2 = new ArrayList();
	ArrayList myList3 = new ArrayList();
        
	myList1.Add("A");
	myList1.Add("B");
	myList1.Add("C");
	myList1.Add("D");
	myList1.Add("E");
	myList1.Add("F");
	myList1.Add("G");
	myList1.Add("H");

	myList2.Add("1");
	myList2.Add("2");
	myList2.Add("3");
	myList2.Add("4");
	myList2.Add("5");
	myList2.Add("6");
	myList2.Add("7");
	myList2.Add("8");
 
	myList3.Add("x");
	myList3.Add("x");
	myList3.Add("x");
	myList3.Add("x");
	myList3.Add("x");
	myList3.Add("x");
	myList3.Add("x");
	myList3.Add("x");

	data.Add(myList1);
	data.Add(myList2);
	data.Add(myList3);
        
	return data;
}

[CODE=css]for(int j = 0; j < ((ArrayList)lis t[0]).Count; j ++) {
String val = "";
for(int i =0; i < list.Count;i++) {
val += (String)((Array List)list[i])[j];

}
Console.WriteLi ne(val);

} [/CODE]

Generic list doesn't require the ugly casts
