How to paste a byte array into a file c#?

Question

When my program starts, i get the byte array of a file (file a), then i send that byte array to paste it into another file (file b), like creating a copy of my first file.

The Question is, how do i open the "file b" and paste the binary info to create a copy of my "file a"?

Answer 1

You can write a byte[] directly to a file path.

using System.IO;

byte[] byteArray;
string path = @"C:\fileB.txt"

File.WriteAllBytes(path, byteArray);
