问题
Is there a library for C# that allows similar functionality to python's struct from the standard library?
One can emulate the struct library quite closely with real aligned structs. But I didn't find yet any way to directly control the endianess in C#'s structs (the C#'s structs seems to be geared more towards COM interop, and less toward general purpose binary packing).
回答1:
The closest equivalent would probably be to use BinaryWriter writing into a MemoryStream, or BitConverter for a one-off conversion of a single value into a byte array.
If you want to control the endianness of that, you can use my EndianBinaryWriter/EndianBitConverter from MiscUtil. One extra feature of my EndianBitConverter is that you can convert into a specific portion of an existing array, which would help you if you wanted to port struct.pack yourself.
