Question

I want to create a binary file in C#.net – the file should contain some header information
and binary data.

The CFile provides the provision to create a same file in the text mode as well as binary mode.

In C# .net a TextWriter and BinaryFormatter to do this. Is it possible to use a single stream class?

Note : Header information should be plain text.

Answer 1

You could use a BinaryWriter:

using (var stream = File.Create("foo.dat"))
using (var writer = new BinaryWriter(stream))
{
    ...
}
