No, it won't, and I've got code to prove it. The function I'm calling returns an allocated array. That means I don't have to allocate it myself. However, I do have to initialize it to null so that it works on the first call.

BinaryReader reader       = null;
FileStream   streamSource = null;
byte[]       fileBytes    = null;

try
{
    streamSource  = new FileStream("c:\\myfile.dat", FileMode.Open, FileAccess.Read, FileShare.None);
    reader        = new BinaryReader(streamSource);

    do
    {
	fileBytes = reader.ReadBytes(65536);
	if (fileBytes.Length != 0)
	{
	    // do something...
	}
    } while (fileBytes.Length != 0);
}

catch (Exception ex)
{
    if (ex != null) {}
    this.m_lastError = 33;
}

finally
{
    if (reader != null)
    {
        reader.Close();
    }
    if (streamSource != null)
    {
        streamSource.Close();
    }
}


In the example I posted, fileBytes will contain one of three thins - a 65536-byte array, and n-byte array (comprised of the last bit of data in the file), or a 0-byte array, indicating no data read from the file (EOF).

In each of those three cases, the array is exactly the length of the retrieved data, and the array is never "null".
