A StreamReader is for text  not plain bytes  Don t use a StreamReader  and instead read directly from the underlying stream

Just throw everything you read into a MemoryStream and get the byte array in the end   As noted  you should be reading from the underlying stream to get the raw bytes   var bytes   default byte     using  var memstream   new MemoryStream          var buffer   new byte 512       var bytesRead   default int       while   bytesRead   reader BaseStream Read buffer  0  buffer Length    gt  0          memstream Write buffer  0  bytesRead       bytes   memstream ToArray        Or if you don t want to manage the buffers   var bytes   default byte     using  var memstream   new MemoryStream          reader BaseStream CopyTo memstream       bytes   memstream ToArray

For everyone saying to get the bytes  copy it to MemoryStream  etc  - if the content isn t expected to be larger than computer s memory should be reasonably be expected to allow  why not just use StreamReader s built in ReadLine   or ReadToEnd     I saw these weren t even mentioned  and they do everything for you     I had a use-case where I just wanted to store the path of a SQLite file from a FileDialogResult that the user picks during the synching initialization process   My program then later needs to use this path when it is run for normal application processes   Maybe not the ideal way to capture re-use the information  but it s not much different than writing to reading from an  ini file - I just didn t want to set one up for one value   So I just read it from a flat  one-line text file   Here s what I did   string filePath   Path GetDirectoryName Assembly GetExecutingAssembly   Location   if   filePath EndsWith        temppath             ensures we have a slash on the end filePath   filePath Replace                  Visual Studio escapes slashes by putting double-slashes in their results - this ensures we don t have double-slashes filePath     SQLite txt    string path   String Empty  FileStream fs   new FileStream filePath  FileMode Open   StreamReader sr   new StreamReader fs   path   sr ReadLine        can also use sr ReadToEnd    sr Close    fs Close    fs Flush     return path    If you REALLY need a byte   instead of a string for some reason  using my example  you can always do   byte   toBytes  FileStream fs   new FileStream filePath  FileMode Open   StreamReader sr   new StreamReader fs   toBytes   Encoding ASCII GetBytes path   sr Close    fs Close    fs Flush     return toBytes     Returning toBytes instead of path      If you don t want ASCII you can easily replace that with UTF8  Unicode  etc

You can also use CopyTo   var ms   new MemoryStream    yourStreamReader BaseStream CopyTo ms      blocking call till the end of the stream ms GetBuffer   CopyTo yourArray  ms Length     or  var ms   new MemoryStream    var ct   yourStreamReader BaseStream CopyToAsync ms   await ct  ms GetBuffer   CopyTo yourArray  ms Length

You can use this code  You shouldn t use this code   byte   bytes   streamReader CurrentEncoding GetBytes streamReader ReadToEnd       Please see the comment to this answer as to why  I will leave the answer  so people know about the problems with this approach  because I didn t up till now
