Does C# support struct bit definitions?. For example is there a way to
declare a structure like this in c#.

C#

typedef struct
{
    UINT16 SrcPort;
    UINT16 DstPort;
    UINT32 SeqNum;
    UINT32 AckNum;
    UINT16 Reserved1:4;
    UINT16 HdrLength:4;
    UINT16 Fin:1;
    UINT16 Syn:1;
    UINT16 Rst:1;
    UINT16 Psh:1;
    UINT16 Ack:1;
    UINT16 Urg:1;
    UINT16 Reserved2:2;
    UINT16 Window;
    UINT16 Checksum;
    UINT16 UrgPtr;
} DIVERT_TCPHDR

Please help me to set bit positions in c# structure. It is very urgent.

Solution 1

The simple answer is "no" - there is no C# equivalent of C++ bit fields.

However you might want to have a look at this: http://stackoverflow.com/questions/14464/bit-fields-in-c-sharp[^] which does provide a helper class that might assist, with a bit of work.
