你能删除存储在HttpContext.Current.Application [“variable”]中的值吗？

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

您可以使用Application.Remove ， Application.RemoveAll和Application.RemoveAt方法。

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.

Answer 3

HttpContext.Current.Application.Remove(...)
