How Does DotNet Handle Parametrized Dates Where Programmatic Date Has No Time But Sql Date Has Time

Thought I'd see if Stack overflow is quicker than me testing something while I get a thousand interruptions from other work :)

I'm updating an old VB net application and trying to refactor some of the logic as I go. The app looks for data from a single date across a few tables and writes that view to a file.

Writing the query in SQL I'd get the equivalent of

SELECT * FROM table
WHERE CAST(FLOOR(CAST(table.date AS float))AS datetime) = '15-Jul-2010'

Ideally I'd use

SELECT * FROM table WHERE date=@input

and add a date object as a parameter to a System.Data.SqlClient.SqlCommand instance

Are those two comparable? Will I get the results I expect?
