I am storing attachments in my applications.
These gets stored in SQL as varbinary types.
I then read them into byte[] object.
I now need to open these files but dont want to first write the files to disk and then open using Process.Start().
I would like to open using inmemory streams. Is there a way to to this in .net. Please note these files can be of any type

Using File. The static File class in the System.IO namespace provides a simple static method WriteAllBytes() that we can use to write all the data from a byte array to a file. => File. WriteAllBytes(filePath, data); public static void SaveByteArrayToFileWithStaticMethod(byte[] data, string filePath) => File.
In order to convert a byte array to a file, we will be using a method named the getBytes() method of String class. Implementation: Convert a String into a byte array and write it in a file.
You can write all bytes to file without using Streams:
System.IO.File.WriteAllBytes(path, bytes);
And then just use
Process.Start(path);
Trying to open file from memory isn't worth the result. Really, you don't want to do it.
