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

Many thanks for your reply. I am not able to add the assembly file in VS 2017. When i try to use system.io.file; in the using statement; it is not listed.

kindly give your feedback.
Cheers

Hi @SathyanarayananAV ,
File is the name of one of the controllers methods, if you want to reference the File class from System.IO namespace, you need to fully qualify the name.
You just need to change File.ReadAllBytes to System.IO.File.ReadAllBytes.

Best regards,
Lan Huang
