At that time, when you wrote down the call to New, the first way of calling it that was presented was to pass a Stream as a parameter. Note the various parameters you have to specify while opening the filestream. In this case, the cached position in the FileStream object and the cached data in the buffer could be compromised.
Open or Create — Open existing file and if file not found then create new file. Notice that this is pretty similar to Example2. Read b, 0, b. This includes setting up various access permissions as well as creation states using enumerations such as FileMode, FileAccess and FileShare.
