error CS0117: 'System.IO.File' does not contain a definition for 'Encrypt'

I'm writing a mobile application using Microsoft Visual Studio 2008 and need to encrypt a file. I tried to use a File.Encrypt method but it resulted in following error:

error CS0117: 'System.IO.File' does not contain a definition for 'Encrypt'.

How can I cope with this problem?

File.Encrypt does not exist within the mobile .NET runtime.

Try using the ProtectedData class.

The reason it won't work is because File.Encrypt actually calls the native Win32 function EncryptFile(LPSTR path), which won't be present on a mobile device.

My suggestion as an alternative would be to use the encryption algorithms present in the System.Security.Cryptography namespace.
