how to realize "#define" macro definition in C#

[xudeutsch]

I have such a block in C++
#pragma pack(push,4)
#define STATE_NULL 0x0000
#pragma pack(pop)

and I need to convert it to C#.

I want to use the "MarshalAs" attribute, but i dont
know which UnmanagedType that hex value belongs to.

Is there another way to realize this convertion ?

thank you very muc

xudeutsch,

You should use a constant for this, like so:

public const int STATE_NULL = 0;

C# does not use pre-processor defines to perform replacement in code, so
you have to use a constant.

Hope this helps.

what about simply

const int StateNull = 0x0000;

thanks, Nicholas and cody.
but as far as i know, the following directive
" #pragma pack(push,4)"
will ensure that: when the data are transferred through
networks to other platforms, the const value "STATE_NULL"
will still be regarded as a 4-byte value in the stack,
namely 0x0000. I dont know whether other statements are
needed or it is default that on every machine this hex value will
be treated as 4-byte. Is that not in 2-byte?

thanks a lot
