Answer 1

You created a naming conflict. The Controller class has a File() method and the System.IO has a static File class. Remove the using statement.

using System.IO;  

Then use the fully qualified name when calling the static File class.

System.IO.File.ReadAllBytes()  

File.ReadAllBytes(String) Method
