Thread safe Static methods how

[Claes R]

Hi !

I would like this class method to be thread safe.

public static ArrayList List(DateTime date)
{
ArrayList l = new ArrayList();
l.Add(new ListItemInfo( 1, "S1010"));
......
return l;
}

How do i accomplish this in a scalable way ?

lock works on a object, not class (or ??)

Would his suffice ??
public static ArrayList List(DateTime date)
{
Monitor.Enter()
ArrayList l = new ArrayList();
l.Add(new ListItemInfo( 1, "S1010"));
......
return l;
Monitor.Exit()
}

Alternatives ??

Thanks
Claes

That is already thread-safe - your not accessing any shared data (in
the code you've shown, anyway).

Hi,

You might provide a static object for locking;

private static object lockingObject = new Object();

and use it for locking:

public static ArrayList List(DateTime date)
{
lock(lockingObject )
{
// your code
}
}
