Stream object needs to be passed inside the constructor of BinaryReader in order to create its instance. This is a guide to C BinaryReader.

The System. BinaryReader class is used to read primitive. Create a BinaryReader The BinaryWriter constructor has overloaded forms to support a stream and encoding. The following code snippet creates BinaryWriter objects with a stream and character encoding format.

Open fileName, FileMode. Create , ascii ; Reading a Binary File The Read overloaded method is used to write primitive data types to a stream. Generally, I don't really see a possible way to do this. I've exhausted all of the options that the earlier comments gave you, and they don't seem to work.

You could try this:. That's the save button. This works fine, but only shows the '! This cannot be run in DOS-Mode! How are we doing? Please help us improve Stack Overflow. Take our short survey.

In other words, if you open the file in a text editor like Notepad, do you see zeros and ones? When you create a new instance of the BinaryReader class, you provide the stream to read from, and optionally specify the type of encoding and whether to leave the stream open after disposing the BinaryReader object.

If you do not specify an encoding type, UTF-8 is used. This type implements the IDisposable interface. When you have finished using the type, you should dispose of it either directly or indirectly. To dispose of it indirectly, use a language construct such as using in C or Using in Visual Basic.

Initializes a new instance of the BinaryReader class based on the specified stream and using UTF-8 encoding. Initializes a new instance of the BinaryReader class based on the specified stream and character encoding. Initializes a new instance of the BinaryReader class based on the specified stream and character encoding, and optionally leaves the stream open.

Exposes access to the underlying stream of the BinaryReader. Releases all resources used by the current instance of the BinaryReader class. Releases the unmanaged resources used by the BinaryReader class and optionally releases the managed resources. Gets the Type of the current instance.

Creates a shallow copy of the current Object. Reads characters from the underlying stream and advances the current position of the stream in accordance with the Encoding used and the specific character being read from the stream. Reads the specified number of bytes from the stream, starting from a specified point in the byte array.

Reads the specified number of characters from the stream, starting from a specified point in the character array. Reads a sequence of bytes from the current stream and advances the position within the stream by the number of bytes read. Reads, from the current stream, the same number of characters as the length of the provided buffer, writes them in the provided buffer, and advances the current position in accordance with the Encoding used and the specific character being read from the stream.
