Is it possible to get byte[] from FileResult?

Question

Is it possible to get byte[] from FileResult in C#?

Koester

If you need the file bytes why not just read the file directly? FileResult is the wrong type to use. – Unsuccessful

@Unsuccessful Well I don't have access to that functionality. I have access to get FileResult only. – Koester

Answer 1

FileResult is an abstract class so that won't be the underlying instance type - assuming the correct overload is used then you should be able to cast it to a FileContentResult

if (result is FileContentResult data)
{
    var content = data.FileContents;
}

FWIW for the sake of code clarity, i think an explicit cast would be preferred in this situation as you'd prefer an InvalidCastException over a NullReferenceException. – Dermatophyte

@YuvalItzchakov I'd like think neither would be preferred :) – Ihram
