Question

I need to convert an .sdf file to a binary file. (I think with streamreader?) Then I need to convert this binary file back to .sdf. How do I do this?

Answer 1

The file itself is already binary, so I’m assuming that you want to read the file into memory as binary. Give this a shot:

public byte[] ReadBinaryFile(string path) {         byte[] data;      using (System.IO.FileStream stream = new System.IO.FileStream(path, System.IO.FileMode.Open))     {         data = new byte[stream.Length];          stream.Read(data, 0, data.Length);     }      return data; } 

If you want to write this byte[] back to the file, do this:

public void WriteBinaryFile(string path, byte[] data) {     using (System.IO.FileStream stream = new System.IO.FileStream(path, System.IO.FileMode.Create))     {         stream.Write(data, 0, data.Length);     } }

Edit

I’ve updated this to encapsulate the logic into two functions.
