BinaryReader reader = new BinaryReader(stream); uint value = reader.ReadUInt32BigEndian();
byte[] buffer = new byte[4]; stream.Read(buffer, 0, buffer.Length); Array.Reverse(buffer); uint value = BitConverter.ToUInt32(buffer, 0);This code reads 4 bytes from a stream into a byte array, reverses the byte order, converts the byte array to an unsigned 32-bit integer using the BitConverter class. The System.IO namespace is a package library that provides classes for working with files, directories, and streams in C#.
