C# SQL Top as parameter

Trying to parameterize the value of TOP in my sql statement.

SELECT TOP @topparam * from table1  command.Parameters.Add("@topparam",SqlDbType.VarChar, 10).Value = somevalue.ToString(); 

This doesn't seem to work. Anyone have any suggestions?
Just to clarify, I don't want to use stored procedures.
