Title Body

Okay the basic idea what I'm trying to do is, converting byte array to something like short or int etc. etc. A simple example might be: unsafe { fixed (byte* byteArray = new byte[5] { 255, 255, 255, 126, 34 }) { short shortSingle = *(short*)byteArray; MessageBox.Show((shortSingle).ToString()); // works fine output is -1 } } Okay, so what I'm really trying to do is, make an extension to Stream class; extended read and write methods. I need help at the following code: unsafe public static T Read<T>(this Stream stream) { int bytesToRead = sizeof(T); // ERROR: Cannot take the address of, get the size of, or declare a pointer to a managed type ('T') byte[] buffer = new byte[bytesToRead]; if (bytesToRead != stream.Read(buffer, 0, bytesToRead)) { throw new Exception(); } fixed (byte* byteArray = buffer) { T typeSingle = *(T*)byteArray; // ERROR: Cannot take the address of, get the size of, or declare a pointer to a managed type ('T') return typeSingle; } } unsafe public static T[] Read<T>(this Stream stream, int count) { // haven't figured out it yet. This is where I read and return T arrays } I feel like I have to use pointers for speed because I will be working on writting and reading data from streams like NetworkStream classes. Thanks for your help! EDIT: And while I try to figure out how may I return T arrays, I've faced with this problem: unsafe { fixed (byte* byteArray = new byte[5] { 0, 0, 255, 255, 34 }) { short* shortArray = (short*)byteArray; MessageBox.Show((shortArray[0]).ToString()); // work
