I dont understand your question but for me it seems you want a if.

if (datatable.rows.count < 0)
{
// your code
}

check this for more information about if-else:

Sorry if I didn't understood your question properly, tried my best im still a beginner too.

Hi,
i edited your question as par my understanding.

let see there will be two cases

C#

if (datatable.rows.count > 0)
{
   // this code will run if data table has more than 0 rows, means there is at least 1 row in  data table, data table is not empty.
}

C#

if (datatable.rows.count < 1)
{
   // this code will run if data table does not has any data (means empty data table, 0 rows).
}

as you are saying

datatable.rows.count < 0

it means data table has less than zero row. even if a data table is empty still it's row count is zero (0).

so row count in negative number doesn't makes any seance.

Please explain your question by giving some good example, so we can understand.
