Syntax for "NULL" in asp.net

[xianxian chan]

Hi everyone,

what is the syntax for NULL if u guys know of any..


Cache.Add("ProductsTable", s, null, DateTime.Now.AddSeconds(60),
TimeSpan.Zero, CacheItemPriority.High, null)


i tried writing the code like this but when i put my mouse pointer over
the blue curly underline on the word "null", it says:-

'null' is not declared. 'Null' constant is no longer supported; use
'System.DBNull' instead.

Then, when i replace the word "null" with 'System.DBNull',
it says 'DBNull' is a type in 'System' and cannot be used as an
expression.

So what am i supposed to use for a NULL object?
