c# - BinaryWriter Endian issue

Question

I am using BinaryWriter class to write a binary file to disk. When I invoke the Write method, passing an unsigned short value, it writes it in little-endian format. For example:

bw.Write(0xA000);

writes the value in the binary file as 0x00 0xA0. Is there a way to make BInaryWriter use Big Endian? If not, is it possible to create a new class, inheriting BinaryWriter and overload the Write function to make it write big endian?

Answer 1

You can use my EndianBinaryWriter in MiscUtil. That lets you specify the endianness you want. There's also EndianBinaryReader and EndianBitConverter.

EndianBinaryWriter writer = new EndianBinaryWriter(EndianBitConverter.Big,
                                                   stream);
writer.Write(...);

It doesn't derive from BinaryWriter, for reasons given in a blog post.
