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?

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.

Looks like exactly what I need (although my project is .NET 2.0). I will try it out! Thanks! – Icemanind Oct 08 '09 at 20:37

There's a .NET 2.0 version of MiscUtil which you can download - it should be fine. – Jon Skeet Oct 08 '09 at 20:38
