ArrayList and Struct

[Ching-Lung]

Hi,

The code:

class Row
{
public int m_Id;
public string m_Name;

public Row(int id, string name)
{
m_Id = id;
m_Name = name;
}
}

class Table
{
public ArrayList m_Table;

public Table()
{
Row row1 = new Row(5, "hello");
Row row2 = new Row(10, "world");

m_Table = new ArrayList(2);
m_Table.Add(row );
m_Table.Add(row 2);
}

public int GetId(int rowNumber)
{
return m_Table[rowNumber].???
}

public string GetName(int rowNumber)
{
return m_Table[rowNumber].???
}
}

If I call Table.GetId(0), it should return 5. If I call
Table.GetName(1 ), it should return "world".

So, how do I access the public members of class Row from
the ArrayList in class Table?

Please help. Thanks!

Hi...

Try this

((Row)m_Table[rowNumber]).Row;
cast it as a Row and use properties:
