How to declare timer?

If I use the following code, the declaration is fine.
//no namespace
private System.Timers.Timer Clock;

This gives the error, "'Timer' is an ambiguous reference".
using System.Timers; //namespace doesn't make a difference
....
private Timer Clock;

What am I doing wrong?

Thanks,
Brett

There's more than one class called "Timer" in the framework.

System.Threading.Timer
System.Timers.Timer
System.Windows.Forms.Timer

Maybe more.

You already have one in scope, and adding the using directive brings in
another.

I see. I am doing this which brings in two timers:
using System.Windows.Forms;
using System.Threading;

I could narrow down the Clock declaration by providing a full path. Is
there another way?

Problem is that Timer exists in System.Windows.Forms namespace as well.
I think you have declared using System.Windows.Forms and using System.Timers
at once.

You can alias namespaces like this:

using Stuff = System.Timers;
....
private Stuff.Timer Clock;

Ok, thanks.

Why if I do something like
this.IE_Inst.Stop();
C# will not automatically put the parentheses on Stop() so I get a compiler
error.
