C＃是否支持结构位定义 [英] Does C# support struct bit definitions

问题描述

C＃是否支持struct bit definitions？例如，是否有一种方法可以在c＃中声明这样的结构。

 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确认： 1 ; 
 UINT16 Urg： 1 ; 
 UINT16 Reserved2： 2 ; 
 UINT16窗口; 
 UINT16校验和; 
 UINT16 UrgPtr; 
} DIVERT_TCPHDR 

请帮我设置c＃结构中的位位置。这是非常紧急的。

解决方案

简单的答案是不 - 没有C＃等价的C ++位字段。



但是你可能想看看这个： http：// stackoverflow .com / questions / 14464 / bit-fields-in-c-sharp [ ^ ]它提供了一个可能有帮助的辅助类，只需要一些工作。

在 Stack Overflow 一些想法：C＃中的位字段 [ ^ ]。

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

解决方案

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.

At Stack Overflow some ideas: "Bit fields in C#"[^].
