How to use C# BinaryWriter Class

C# BinaryWriter Object works at lower level of Streams. C# BinaryWriter Class is using for write primitive types as binary values in a specific encoding stream. C# BinaryWriter Object works with Stream Objects that provide access to the underlying bytes. For creating a BinaryWriter Object , you have to first create a FileStream Object and then pass BinaryWriter to the constructor method .

FileStream writeStream ; writeStream = new FileStream("c:\\testBinary.dat", FileMode.Create);
BinaryWriter writeBinay = new BinaryWriter(writeStream);

The main advantages of Binary information is that it is not easily human readable and stores files as Binary format is the best practice of space utilization.
