Can you delete values stored in HttpContext.Current.Application["variable"]?

Question

Can you delete values stored in HttpContext.Current.Application["variable"]? Or is the only way to do this is by setting it to an empty string?

Answer 1

You can use Application.Remove, Application.RemoveAll, and Application.RemoveAt methods.

Answer 2

Use

HttpContext.Current.Application.Remove("variable");

Also, setting to null is fine since if you try to read HttpContext.Current.Application["variable"] and there is no value there, it will return null anyway, but of course better to be explicit if what you want is remove.
