Question 11

You are developing a new ASP.NET web application that performs complex mathematical calculations for 3D graphics rendering. This application will be used by architects working in the field. As part of the design of the application, users can generate calculations and save the results to a flat file which can be read later. You need to store 20 double-precision floating point numbers to a disk file on the server. You must minimize the size of the disk file to conserve disk space on the server.

Which object should you use to create the file?



The correct answer is BinaryWriter. The BinaryWriter object provides an extremely compact format for data storage to disk. However, remember it does not store the data in a human readable format! In this case, the data is read back by the application and not by a human.
