Accessing Arraylists

[Dogmar Hoffman]

Hello,

ArrayList arrTestArrayList =
TestArrayList.LoadTestRecords(ConnectionString,Sta rtDate,EndDate);

and it is in the same public class and namespace that I am trying to
access it from. Basically, I am looking for a way to test against the
value at position 6 in that arraylist like:

If (x = valueAtArrayList[6])
{
Do Something;
}

Any help on this would be greatly appreciated. Thank you!

Hi,

What is the error you are getting?

I think you used the assignment operator = instead of the comparision
operator ==
Also remember that you are getting an object reference, so you need to cast
it to the type of "x" variable:

int x=1;
if ( x == (int) arrTestArrayList [5] )

Also as ArrayList start at index 0 the 6th element is at position 5

Actually, a better representation is:

public int one(string conn,DateTime start,DateTime end)
{
try
{
ArrayList arrTestArrayList =
TestArrayList.LoadTestRecords(ConnectionString,Sta rtDate,EndDate);

foreach(thing something in anything)
{
something.Load(arrTestArrayList);
}
}
return 1;
}

public int GetStuff()
{
try
{
If (x = value in TestArrayList[6])
{
Do Something;
}
}
}

So in GetStuff, I would like to be able to get the values from
TestArrayList. Thank you very much and I hope that this is clearer.

What does the LoadTestRecords method do? What exactly is getting
loaded into the arraylist? Strings? Integers? Instances of some
class?

If the items in the arraylist are strings then you would use:

if (x == arrTestArrayList[6].ToString())

If the items are integers:

if (x == (int)arrTestArrayList[6])

If they are instances of some class and you are comparing a single
property:

MyClassName m = (MyClassName) arrTestArray[6];
if (x == m.SomeProperty)
So it depends on what the items in the arraylist are. You must cast
the object to the appropriate type.

The error that I am getting is that arrTestArrayList does not exist in
the class or namespace. Thank you again!
