Convert music file to byte array c# like matlab

Question

I would like to convert any music file into a byte array and print the result in c# just like in MATLAB.

I tried this;

System.IO.FileStream _FileStream = new System.IO.FileStream(_FileName, System.IO.FileMode.Open, System.IO.FileAccess.Read);
System.IO.BinaryReader _BinaryReader = new System.IO.BinaryReader(_FileStream);

long _TotalBytes = new System.IO.FileInfo(_FileName).Length;
_Buffer = _BinaryReader.ReadBytes((Int32)_TotalBytes);

And the code to print to console:

Console.WriteLine( byteArrayToString(fileToByteArray("Penguins.jpg")) );

where the method's code is:

private static string byteArrayToString(byte[] p)
{
    string result = System.Text.ASCIIEncoding.ASCII.GetString(p);
    return result;
}

When I run this code, console becomes crazy with irrelevant characters, however I would like to have an array like MATLAB's output.

How should I do that ?

Thanks.

FYI, this code can be simplified to File.ReadAllBytes(_FileName)... — Thomas Levesque

And where's the code that prints to the console? You're only showing how you load the data from the file — Thomas Levesque

Code is: Console.WriteLine(byteArrayToString(fileToByteArray("C:\\Users\\Public\\Pictures\\Sample Pictures/Penguins.jpg"))); and the method's code is: private static string byteArrayToString(byte[] p) { string result = System.Text.ASCIIEncoding.ASCII.GetString(p); return result; } — Can

don't post it in a comment, its really hard to read... edit your question instead — Thomas Levesque

If you just want the byte array of any file just do the following:

byte[] byteArrayFile = File.ReadAllBytes(source);
//source is the path to the file

Do you really want characters? If you just want the numbers, build a string with the numbers. I don't know matlabs format, but say for a row vector like [N1,N2,N3]

private static string ByteArrayToString(byte[] p)
{
     StringBuilder sb = new StringBuilder("[");
     for(int i=0; i<p.Length; i++)
     {
          sb.Append(p[i]);
          if (i < p.Length - 1)
              sb.Append(',');
     }
     sb.Append("]");
     return sb.ToString();
}
